    Key requirements in the procurement of future low observablecombat vehicles: a European perspective2018In: Systems Engineering, ISSN 1098-1241, E-ISSN 1520-6858, Vol. 21, no 1, p. 3-15Article in journal (Refereed)
    Abstract [en]

    The aim of this study is to propose guidelines for the systems engineering of future stealth combat vehicles using Low Observable Technology (LOT). A case study approach, based on interviews and document reviews, was used to analyze the systems engineering processes of the SEP multirole armored vehicle and the Visby class corvette respectively. The result is a thorough investigation of what worked in the cases studied, butwith lessons extrapolated into recommendations for future development programs. These will have to deal with an increasingly complex sensor threat and a transformed, multilateral, European procurement environment. The main conclusion is that coherence and traceability between military needs on the battlefield and signature requirements is expected to be particularly challenging. A workflow tailored for requirements analysis in LO combat vehicle programs has, therefore, been derived and is presented here. In addition, themost important enablers for future multilateral development programs involving LOT have been identified as: establishing common best practices, demonstrator programs, an integrated product team approach, and, in line with similar work on combat aircraft, establishing stealth as a key architectural  principle.

    Modeling the impact of surface emissivity on the military utility of attack aircraft2017In: Aerospace Science and Technology, ISSN 1270-9638, E-ISSN 1626-3219, Vol. 65, p. 133-140Article in journal (Refereed)
    Abstract [en]

    An analysis scheme and a mission system model were applied to the evaluation of the military utility of efforts to reduce infrared signature in the conceptual design of survivable aircraft. The purpose is twofold: Firstly, to contribute to the development of a methodological framework for assessing the military utility of spectral design, and secondly to assess the threat from advances in LWIR sensors and their use in surface-to-air-missile systems. The modeling was specifically applied to the problem of linking the emissivity of aircraft coatings to mission accomplishment. The overall results indicate that the analysis scheme and mission system model applied are feasible for assessing the military utility of spectral design and for supporting decision-making in the concept phase. The analysis of different strike options suggests that LWIR sensors will enhance the military utility of low emissive paint, at least for missions executed in clear weather conditions. Furthermore, results corroborate and further clarify the importance of including earthshine when modeling.

    On the Military Utility of Spectral Design in Signature Management: a Systems Approach2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    There is an ongoing duel between military sensor development and developments in signature management. The last decade, with warfare characterized by joint expeditionary operations and asymmetry, has favored sensors. However, on account of the worsening security situation in Europe, there is now also an increasing interest in efforts to increase survivability of own military platforms. Spectral design is one of several promising technologies with extensive research potentially suitable for Low Observable platforms. It involves creating desired spectral optical responses from surfaces, in this case reducing contrast to background, by choosing suitable materials and structures. The challenge to a military decision-maker, faced with inherent uncertainties concerning the future and with limited resources, is how to choose among alternative capabilities, technologies or equipment. Correspondingly, on account of the system character of the signature attribute, researchers in technologies for signature management has difficulties communicating relevant basis for these decisions. The scope of this thesis is therefore to find and analyze patterns in decision situations involving technology or technical systems for military use, and the purpose is to propose conceptual and methodological contributions to support future decisionmaking. The technology focus is on spectral design and the application in focus is signature management of Low Observable military platforms. The research objective is addressed from a military system and capability centric perspective using methods from several disciplines in the military sciences domain. The result is synthesized from four separate studies: 1) on spectral design using systematic review of literature, 2) on military utility using a concept formation method, 3) on modeling for how to operationalize a link between spectral design and measures of military utility using methods of military operations research, and, 4) on cases of systems engineering of military Low Observable platform designs. In summary, the result of the work presented in this thesis is a compilation of related work in military sciences, systems engineering and material optics into a framework to support effective decision-making in relevant contexts. The major contribution to theory is a proposed concept called Military Utility, capturing how to communicate the utility of technical systems, or technology, in a military context. It is a compound measure of Military Effectiveness, Military Suitability and Affordability. Other contributions can be expected to support decision-making in practice; - the so-called Ladder-model is a template for how to quantitatively operationalize the military effectiveness dimension of Military Utility regarding the use of spectral design; - an applied Ladder-model is demonstrated, useful for analyzing the military utility of spectral designs in Low Observable attack aircraft; - a probabilistic framework for survivability assessments is adopted into a methodology for doing the analysis, and lastly; - a generic workflow is identified, from relevant development programs, including decision-situations that can benefit from the adopted methodology.

    Technology Forecast 2012: Military utility of ten technologies: a report from seminars at the SNDC Department of Military Technology2012Report (Other academic)
    Abstract [en]

    Ten technology forecast reports from the Fraunhofer Institute have been reviewed by staff at the Department of Military-Technology at the Swedish National Defence College (Note that there probably are other technology areas, equally interesting, but not included in this study). The task given by FMV was to assess the military utility of the chosen technologies in a time frame from 2025 to 2030, from a SwAF viewpoint.

    The method used was first to make a summary of each forecast report. The technology was then put into one or more scenarios that are assessed to be the best in order to show possible utility as well as possibilities and drawbacks of the technology. Based on a SWOT-analysis, the contribution to SwAF capabilities and the cost in terms of acquisition, C2 footprint, logistic footprint, doctrine/TTP, training, facilities and R&D were assessed. Conclusions regarding the military utility of the technology were drawn.

    We introduce our definition of military utility as being activities that efficiently and with the lowest cost in terms of lives and materiel lead to fulfilment of the mission objectives.

    The technologies were grouped in three classes; technologies with a significant potential, with uncertain potential and with negligible potential.

    The following technologies were assessed to have a significant potential for military utility;

    • Augmented Reality

    • Nano air vehicles
    • Solid State Laser weapons

    In the scenarios studied, Augmented Reality (AR) is assessed to have a positive impact on several SwAF capabilities, especially for C2 and intelligence. AR is a relatively mature technology, applicable in many different branches. There are examples where AR is already applied with great success, e.g. Head-Up-Displays, HUD. The technology has proven its value. However, there are well known drawbacks to the technology such as weaknesses regarding models, increased weight for dismounted soldiers, power consumption etc. There is also a risk that personnel will have problems solving their tasks when AR systems fail, not being used to fighting without supporting systems.

    Nano air vehicles (NAV’s) have been assessed to contribute to a large range of capabilities, primarily intelligence. Their lifecycle cost has been assessed to be low, since development in this area is commercially driven, bringing down acquisition costs. Also, FAA has decided to allow NAV’s in controlled air space from 2015, which is expected to lead to an increase in civilian use of NAV’s. The technology is relatively mature even though there are obstacles concerning suitable materials, energy efficient propulsion systems as well as miniaturized microprocessors and software to control them.

    In the scenario studied, High Energy Solid State Lasers are assessed to have a positive impact on SwAF capabilities to engage targets on surface and in the air. The technology can be used to protect 

    vessels on the surface and thereby increase survivability. The development of SSL in the given timeframe is expected to lower cost per shot and avoid the environmental problems with use of chemical lasers. Neighbouring military powers are expected to use laser weapons in the future, therefore SwAF should monitor the development of the laser weapons technology and develop and purchase adequate countermeasures.

    The following technologies were assessed to have uncertain potential for military utility;

    • Metamaterial cloaking

    • Electromagnetic gun

    • Small satellites
    • Ultra-violet communication

    Metamaterial cloaking, if realisable in the future, is assessed to be firstly implemented in the acoustic spectrum, since manufacturing of small structured cloaks for the shorter wavelengths in the optic and radar spectra is believed to be more difficult. Cloaking of submarines is primarily assessed to increase the survivability against torpedoes having active sonar. The use of cloaked mines could pose a deterring threat, even to advanced amphibious operations against Sweden. The technological development in this area should be closely monitored and compared to existing, maturing techniques for countermeasures and for the development of broad spectrum active torpedoes. The greatest concern is that cloaking will have negative impact on submarine manoeuvrability.

    The electro-thermal chemical (ETC) gun seems to be a first step towards a fully electrical gun such as the rail-gun or the coil-gun. The fully electrical guns have been a work in progress for some decades and there are still remaining challenges both concerning electrical power supply and design materials. When or if, they will be operational is difficult to say.

    The military utility of small satellites is disputed, despite an assessed contribution to several of the SwAF capabilities. The main reason for this is that there seems to be other alternatives which provide the desired capabilities, at a lower cost. Furthermore, the realisability and performance of small productionline manufactured nanosatellites is uncertain. However the scenario has shown that there are benefits to the military utility not met by other resources, e.g. the capability to perform surveillance and reconnaissance in operational areas globally without risking violation of the territorial integrity of other states or the lives of military personnel. Since there is a great interest in the technology area and several programmes are ongoing internationally the knowledgebase is assessed to be significantly better in a five year period. Also, the Swedish in depth study of space exploitation is soon to report.

    Ultra-violet communication has uncertain potential for military utility within the period, but the technology is assessed to have a positive impact on SwAF capability to maintain communications. The theoretical understanding of the area is low It is therefore uncertain if systems can be realized in the time frame. However, if commercial applications are developed, the prospect of military applications might change. In that case UV-communication could be a complement to RF- communication but is not foreseen to replace it. 

    The following technologies were assessed to have negligible potential for military utility;

    • Biomimetic unmanned underwater vehicles (UUV)

    • Automated behaviour Analysis
    • Evolutionary Robotics

    Biomimetic UUV’s could be used for covert surveillance and inconspicuous naval reconnaissance missions at sea or in amphibious missions. Even though the report focuses on fishlike propulsion, the military utility of UUV’s is assessed to be mostly dependent on the development of advanced automation and learning systems. As of now, we assess other existing technologies as being preferable due to lower cost and less complexity. The performance of UUV’s needed for SwAF capabilities are assessed to be far off into the future. Simpler UUV systems could however be used by potential adversaries for monitoring our own base areas and hence the development should be monitored from a protection point of view.

    Automated behaviour analysis may be of some relevance for increased security screening and surveillance. The primary military utility of the technology will however probably be for international activities and to a lesser extent for increased base security in Sweden. Generally the main applications for this kind of technology are assessed to be for civilian use in public spaces and close to high value areas like airports, important official buildings and other similar objects.

    Evolutionary Robotics, here restricted to the sub domain Advanced Robotics, has uncertain potential for military utility within the period. In the scenarios studied the technology is assessed to have a positive impact on a broad range of SwAF capabilities. The area is large and inconsistent comprising sub areas that are assessed to have significant potential, but also those that are believed to have negligible potential or where technological obstacles might retard the development.

    Our evaluation of the used method shows that there is a risk that the assessment is biased by the participating experts’ presumptions and experiences from their own field of research. The scenarios that were chosen do not cover all possible aspects of the technology and their possible contribution to operational capabilities. It should be stressed that we have assessed the ten technologies’ military utility in the presented scenarios, not the technology itself. The chosen definition of military utility clearly affects the result of the study. The definition is believed to be good enough for this report, but could be further elaborated in the future.

    The greatest value of the method used is its simplicity, cost effectiveness and the trade off that it promotes learning within the working group. The composition of the working group and the methodology used is believed to provide for a broad and balanced coverage of the technologies under study.

    Introduktion till Operationsanalys: En antologi med essäer av studerande i militärteknik 20112012Other (Other academic)
    Abstract [sv]

    I ämnesplanen definieras militärteknik som ”den vetenskap som beskriver och förklarar hur tekniken inverkar på militär verksamhet på alla nivåer, strategisk, operativ och taktisk, samt hur officersprofessionen påverkar och påverkas av tekniken.”[1]  En militärteknikers uppgift brukar, utgående från definitionen, uttryckas som att beskriva och förklara den militära nyttan med tekniken. För att kunna göra detta behövs verktyg. Och många av dem kommer från den vetenskapliga disciplinen Operationsanalys.

    Syftet med den här antologin är att introducera studerande i militärteknik på Försvarshögskolan till två av de mest refererade boktitlarna i operationsanalys – Methods for conducting military operational analysis editerad av Andrew G. Loerch och Larry B. Rainey samt Military Operations Research, quantitative decision making av N.K. Jaiswal.

    Kapitlen utgörs av essäer skrivna av studerande på den högre stabsofficersutbildningen med teknisk inriktning, som examinationsuppgift i en fördjupningskurs. Essäerna är till del referat av kapitel i de två böckerna ovan, men kryddade med exempel satta i svenskt sammanhang och med de studerandes egen värdering av metodernas användbarhet.

    A systems approach to stealth on the ground revisited2015In: Target and Background Signatures / [ed] Karin U. Stein & Ric H. M. A. Schleijpen, SPIE - International Society for Optical Engineering, 2015, Vol. 9653Conference paper (Other academic)
    Abstract [en]

    This new security development is expected to increase interest fromNorthern European states in supporting the development of conceptually newstealthy ground platforms, incorporating a decade of advances in technology andexperiences from stealth platforms at sea and in the air. The scope of thiscase study is to draw experience from where we left off. At the end of the1990s there was growing interest in stealth for combat vehicles in Sweden. Anambitious technology demonstrator project was launched. One of the outcomes wasa proposed Systems Engineering process tailored for signature managementpresented to SPIE in 2002.(Olsson et.al, A systems approach…, Proc. SPIE 4718 )The process was used for the Swedish/BAE Systems Hägglunds AB development of amultirole armored platform (The Swedish acronym is SEP). Before development wascompleted there was a change of procurement policy in Sweden from domesticdevelopment towards Governmental Off-The-Shelf, preceded by a Swedish ArmedForces change of focus from national defense only, towards expeditionarymissions. Lessons learned, of value for future development, are presented. Theyare deduced from interviews of key-personnel, on the procurer and industrysides respectively, and from document reviews.

    Förstudie angående DTAG-metodik2010Report (Other (popular science, discussion, etc.))
    Abstract [sv]

    Rapporten utgör slutrapport på FMV beställning ”förstudie angående DTAG-metodik”.

    RTO har genomfört en studie för att utröna hur NATO bäst identifierar och nyttjar eller skyddar sig mot potentialen i s.k. ”Disruptive Technology”, d.v.s. teknologi som på kort tid signifikant förändrar genomförandet av operationer. Sverige har medverkat i studien. Den tillämpning av metoden DTAG (Disruptive Technology Assessment Games) som beskrivs i RTO studierapport är utvecklad till stöd för beslutsfattning på lång sikt, d.v.s. avseende FoT, konceptutveckling, förbandsutveckling- och materielplanering. Idén bakom den här förstudien är emellertid att undersöka möjligheterna att överföra metoden till erfarenhetsanalys och planering i ett kortare tidsperspektiv - med bibehållande av de rapporterade positiva effekterna för erfarenhetsutbytet mellan personal inom försvarsfamiljen av alla kategorier.

    Rapporten inleds med en diskussion och beskrivning av möjliga anpassningar av DTAG för den nya föreslagna tillämpningen. Slutsatsen är att metoden har potential att effektivt återkoppla speldeltagarnas erfarenheter från uppdrag de deltagit i - dels från egen användning av tekniska system och dels från andra aktörers teknologi - till utvecklingen av de materielsystem som bedöms vara i drift inom en tidsperiod av ca fem år. En analys av identifierade styrkor, svagheter, möjligheter och risker leder sedan fram till ett förslag till implementering av metoden och förslag till fortsatt arbete. En positiv bieffekt med att arrangera en återkommande DTAG-aktivitet inom ramen för FHS, i samarbete med FMV och FM, är t.ex. en förbättrad erfarenhetsöverspridning till utbildningen av officerare.

    Förstudien rekommenderar en studie till FHS under 2011 med uppgifterna att:

    • pröva och uppdatera metodramverket till förstudiens DTAG-tillämpning
    • planera och genomföra prov och försök med bemanning enl. förstudiens förslag till organisation
    • genomföra en litteraturstudie och utvärdera den tillämpade DTAG-metoden
    • med andra relevanta metoder och deras tillämpningar avseende: erfarenhetsåtermatning,
    • konceptval och scenariebaserad analys, även i andra domäner än den militära.
    • rapportera skriftligen med rekommendation om implementering av metoden i produktionsledningen av materielprocessen – inkl. lämpliga årliga återkommande tidpunkter för genomförande, m.h.t. rotationer och årliga avvägningar i materielplanen.

    Ett förslag till organisation, aktivitetsplan och en uppskattning av kostnaderna presenteras.

    Effekten av game feel: Hur tillägget av ren game feel påverkar en spelares immersion, jämfört med tillägget av detaljerad grafik, i ett actionspel med kort utvecklingstid2015Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Syftet med detta arbete är att jämföra effekterna av game feel och detaljerad grafik på en spelares immersion. Arbetet är riktat mot korta produktioner och har som mål att redovisa data som gör att spelutvecklare kan göra informerade val vid implementation av funktionalitet och grafik. Tre prototyper skapades för att mäta spelarnas immersion: en med abstrakt grafik, en med detaljerad grafik och en med game feel. Försökpersonernas upplevelse av prototyperna samlades in med hjälp av en webbbaserad enkät. Försökpersonernas svar visar inga säkra resultat men pekar på att försökspersonerna som spelade prototypen med game feel upplevde mest immersion.

    Meningsförändrande innovationer inom industrirobotbranschen: En explorativ fallstudie2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In this thesis the subject innovation and the change of meaning is in focus. The purpose of the study is to present a new dimension of innovation as a change of meaning together with the cases we’ve studied. It is discussed throughout the article if theories of perception and association can affect the organization and its ability to create meaning-changing innovations. The industrial robotics is a market in need of, perhaps, if not other markets but of finding new ground that results in the change of meaning. What happens when you stand at the intersection of main areas in the field of innovation? Is it possible that meaningful change can be found here, amongst radical innovation and industrial robotic arms and it’s technology? Our methods were interviews and prior research complementing the cases we’ve presented. We want to show how meaning can change various dimensions. Together with a perceptual theory and an innovation theory we’ve found out that meaning and innovation can go hand in hand.

    Abstract [en]

    Swedish employers are obliged by law to systematically plan, direct and control activities so that the working environment meets the prescribed requirements. However, evidence indicates that this work is not performed satisfactorily in many schools. This case study aims at mapping out and clarifying how measures towards planning, directing and controlling activities are organized in two public compulsory schools.

     

    The overall purpose of the study is to shed light on elements and conditions that hinder a successful implementation of work environment measures. Our main research questions are: Does the way the municipalities have organized the working environment measures reach the requirements in the law and how controls and follow-ups are performed. Data was collected through the municipalities’ steering documents together with a survey in combination with follow-up interviews with key figures.

     

    Results show that the working environment measures in both schools are organized and performed in similar ways and that the problems reported to a large extent are the same. The unanimous picture shows an organization that is not capable of identifying and handling all important risks. Conclusions from the study indicate that there is a lack of knowledge concerning working environments measures on all levels in the organizations.

    Abstract [en]

    In today’s society, IT-Companies often have a hard time estimating changed requirements. This leads to that the clients’ confidence is negatively affected and is one of the main reasons why this has to be improved. The goal with this study was to find out what the most common problems regarding this issue are in IT-companies that works with agile software development. By analyzing one IT-company through a SWOT- and pareto-analysis the most common problems have been ascertained. The SWOT analysis have been created through interviews with selected employees to get a better understanding of the problems that the IT-company is facing. Furthermore was the pareto-analysis based on a survey that was sent out to many different employees to prioritize the problems. The reason why the survey was sent to different employees was to get a more objective input. The study showed that there was many different problems that needed attention. The most important problems was that the communication towards the client regarding requirements needed to be improved, better communication internally between different departments needed to be established, a method to quickly adapt and estimate change in requirements needed to be implemented and finally a method regarding witch key employees whom need to attend the planning of the program backlog. These problems have then been studied through interviews with other IT-companies and through a literature study. The conclusions that where drawn was that the client needs to be involved and updated through the whole project. Constant monitoring and communication regarding changed requirements needs to be processed and mediated. High standards needs to be set early towards the client in order to obtain as clear an image of the requirements as possible. Many different parties need to attend to the planning process for the program backlog before the start of the project. The client needs to be aware of that changed requirements will arise and that this will lead to that the first estimation may not necessarily be absolute. As long as the client is held up to date as well as participant through the whole project and problems are detected and mediated early, change in requirements should not be a huge problem. This is after all the purpose of being agile.

    In the construction industry, there has been a drop in productivity in recent years, and despite the fact that motivation is a key factor when it comes to create productive work, there seems to be few studies that focus specifically on what motivates the construction worker. The studies that exist actually seem to exclude the great influence of the foreman and impact on the construction worker motivation, which this paper intends to investigate further.

    The aim of the study is therefore to understand what motivates and demotivates the construction worker and understand the role and impact of the foreman on constructions worker motivation. The influence of the foreman on the construction team seems to be non-present in studies and research within the construction industry and therefore, this thesis refers to emphasize this important role.

    The work is performed at the construction company Skanska during the spring term 2015 where the interviews took place with employed construction workers, foremen and supervisors. The study has shown that workers are proud and want to create a quality end product. Standstills and revised planning is common within construction but are obstacles to their creation and a significant demotivator at work. Lack of commitment from other co-workers creates dissatisfaction and irritation, which negatively impacts the overall motivation.

    The position as a foreman requires both extensive knowledge and experience in construction management. As it seems the foreman also should be a people person. The study has shown that the foreman has a major effect on construction worker motivation by scheduling and distribute the work fairly among the workers. It also appears that the foreman has some form of intermediate impact on workers motivation, by adjusting how the worker interprets the external factors that affect their motivation.

    Embracing Blockchain: The Challenges of Collaborative Innovation Within the Financial Industry2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Creating standardized infrastructures for new technologies has become a frequent event in recent years, forcing competing firms to together collaborate in order to develop and mutually agree on a common standard. This is due to technologies such as blockchain (distributed ledger) technology that need interoperability to reach its full potential, making the collaboration aspect crucial for organizations that want to adapt to the technology. Therefore, this study’s purpose is to identify and analyze the challenges of creating such a standardized infrastructure. A case study was used to analyze these challenges, which involved experts of blockchain technology and three Nordic banks connected to the blockchain consortium R3. First, a pre-study took place with the help of blockchain experts, who helped identify potential problems regarding blockchain (distributed ledger) technology. Secondly, a main study was conducted consisting of four interviews with key persons representing the banks, in addition to collecting secondary data via news articles, and press releases. With the help of co-opetition theory and a technical description of blockchain (distributed ledger) technology, an analytical model was developed to support the analysis of the data collection. The analysis focus on aspects of co-opetition drivers, co-opetition capabilities, co-opetition dynamics and blockchain aspects, which were used to showcase the challenges of collaborating on creating a standardized infrastructure. The result of this study highlights the importance of learning and educational aspects, the size of a cooperation and threats from other competing solutions, which generates challenges. In addition to the identified challenges, this study has also contributed to an understanding of how these aspects can come to affect a collaboration.

    Adjusting route charges to increase profit2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Route charges are fees that airlines pay in order to utilize the Air Navigation Services (ANS) of a European state. The fee is based on three values; the weight of the aircraft, the length of the flight, and the state’s specific unit rate. The unit rate of each state is in turn based on the forecasted costs of providing ANS for that state and the amount of traffic forecasted for the year to come.

    This makes for different unit rates for different states, which leads to different costs for flying different routes in the European airspace. A state having costs that are increasing faster than the amount of traffic is increasing will lead to a higher unit rate. A higher unit rate may lead to airlines avoiding the state’s airspace due to higher costs, thus accounting for even less traffic and an increase in unit rate.

    This thesis examines the relationship between unit rate and amount of traffic, and specifically tries to find out how much the unit rate affects the traffic count. This has been done by reading previous papers on the subject, and creating a model to easily present facts found.

    The result of the thesis suggests that states actually profits more by increasing the unit rate rather than actively trying to reduce it. This contradicts the idea of lowering prices always being a good thing. There is a limit to how much the unit rate can be increases however, at which all traffic will choose to circumnavigate the airspace. Finding a good balance between traffic lost and unit rate increased is suggested as the best way to go.

    Möjliga efterträdare till robotsystem 702012Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    For many years, there has been a discussion about the needs to replace missilesystem 70 witha more modern short range air defense unit. The anti-aircraft regiment has prepared a conceptproposal against a possible successor to the current robotsystem. In order to show that thereare other options which can be potential replacements instead of the concept proposal, ananalysis of three quite different launchers is made along certain valuation criteria, which arereflected against the Swedish Armed Forces basic abilities. The analysis is made of three scenariosin order to reflect some of the tasks that a short range air defense has to handle. Thescenarios will also show the advantages and disadvantages of the different units. By the scenariosseven criteria are revealed as extra important to take into account when a new air defenseunit is ordered to be able to solve the expected tasks.These criteria’s are: Multi-Targeting, darkness capacity, performance area, protection of theterrain - camouflage, Small Claims Act, all-weather capability and set up time.

    Thin film metal sensors in fusion bonded glass chips for high-pressure microfluidics2017In: Journal of Micromechanics and Microengineering, ISSN 0960-1317, E-ISSN 1361-6439, Vol. 27, no 1, article id 015018Article in journal (Refereed)
    Abstract [en]

    High-pressure microfluidics offers fast analyses of thermodynamic parameters for compressed process solvents. However, microfluidic platforms handling highly compressible supercritical CO2 are difficult to control, and on-chip sensing would offer added control of the devices. Therefore, there is a need to integrate sensors into highly pressure tolerant glass chips. In this paper, thin film Pt sensors were embedded in shallow etched trenches in a glass wafer that was bonded with another glass wafer having microfluidic channels. The devices having sensors integrated into the flow channels sustained pressures up to 220 bar, typical for the operation of supercritical CO2. No leakage from the devices could be found. Integrated temperature sensors were capable of measuring local decompression cooling effects and integrated calorimetric sensors measured flow velocities over the range 0.5-13.8 mm/s. By this, a better control of high-pressure microfluidic platforms has been achieved.

    Fracture strength of glass chips for high-pressure microfluidics2016In: Journal of Micromechanics and Microengineering, ISSN 0960-1317, E-ISSN 1361-6439, Vol. 26, no 9, article id 095009Article in journal (Refereed)
    Abstract [en]

    High-pressure microfluidics exposes new areas in chemistry. In this paper, the reliability of transparent borosilicate glass chips is investigated. Two designs of circular cavities are used for fracture strength tests, either 1.6 mm wide with rounded corners to the fluid inlets, or 2.0 mm wide with sharp inlet corners. Two kinds of tests are done, either short-term,e.g. pressurization to fracture at room temperature, or long-term, with fracture at constant pressurization for up to one week, in the temperature region 11–125 °C. The speed of crack fronts is measured using a high-speed camera. Results show fracture stresses in the range of 129 and 254 MPa for short-term measurements. Long-term measurements conclude the presences of a temperature and stress dependent delayed fracture. For a reliability ofone week at 11–38 °C, a pressure limit is found at the lower end of the short-term measurements, or 15% lower than the average. At 80 °C, this pressure limit is 45% lower. Crack speeds are measured to be 10−5 m s-1 during short-term fracture. These measurements are comparable with estimations based on slow crack growth and show that the growth affects the reliability of glass chips. This effect is strongly affected by high temperatures, thus lowers the operating window of high-pressure glass microfluidic devices.

    High pressure glass microfluidics for supercritical CO2 with aqueous solutions2016Conference paper (Refereed)
    Abstract [en]

    A microfluidic system is presented to investigate interactions between supercritical CO2 and H2O using high-pressure glass chips. The reliability of these chips at pressures necessary to sustain CO2 in the supercritical phase is dependent of both time and temperature. 130 bar can be kept at 38°C for more than a week. These systems can be used to investigate fluid interaction between supercritical CO2 and aqueous solutions by the addition of pH sensitive dye and high speed absorption light imagining, making it possible to demonstrate acidification is in a multiphase chip. By the addition of integrated temperature sensors, better control of the states of the fluids inside the chips can be achieved.

    Optimization of maintenance system2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This report presents an optimization of the allocation of maintenance resources for Air Navigation Service (ANS) equipment of which LFV is responsible for the maintenance. The purpose the authors have worked after is to research ways of minimizing travelling time linked to maintenance visits for ANS equipment, this report includes the suggestions where the maintenance facilities should be placed in order to minimize the total travelling time. The report describes the problem background and presents the customer, LFV. It includes a chapter on some of the theories used for facility location and routing, and also presents methods for reducing the total travelling time used for maintenance visits annually. The authors have worked with a given set of airports in Sweden. Information about the general work with maintenance as well as the annual demand of maintenance, including the frequency of visits, for each airport included in this project was received by Pär Oberger, the task expert and contact at LFV for this report. A model for facility location based on the p-median model have been created and used when solving the problem, it was written in AMPL and solved with the CPLEX solver. The model was modified with two additional constraints regulating the minimum annual working time and the maximum distance for one-way travelling. The authors deems that a solution with five facilities is better since the benefit of additional facilities, in term of lower total distance, do not compensate for the assumed cost of establishing them.

    Abstract [en]

    The introduction of silicon carbide (SiC) as the semiconductorin gas sensitive field effect devices has tremendously improved this sensor platform extending the temperature range and number of detectable gases. Here we review the recent trends in research, starting with transducer mechanisms, latest findings regarding the detection mechanism, and present new material combinations as sensing layers and smart operation of the field effect sensors enabling one sensor to act as a sensor array. Introducing epitaxially-grown graphene on SiC as gas sensing layer shows the potential of ppb detection of NO2 .

    Radio Frequency Thermal Treatment of Liver Tumours: -Influence of Blood Perfusion and Large Vessels2008Independent thesis Advanced level (degree of Magister), 20 points / 30 hpStudent thesis
    Abstract [en]

    Radio frequency ablation (RFA) is a commonly used minimally invasive method of treating liver cancer tumours which utilises RF current for heating tumour tissue up to a lethal temperature. RF current is generated by a power generator and applied to the tumour by an electrode which is inserted into the tumour either during percutaneous or open surgery.

    RFA is a method that has great advantages compared to traditional surgical resection of tumours due to minimal invasiveness, it can be used for a greater number of patients and enables repeated treatments. Even though there are many advantages coupled to RFA there are still some problems and difficulties associated with the method. One of these problems is the cooling effect from large vessel blood flow within the liver, the so called heat sink effect.

    The aim of this master thesis work has been to develop a theoretical finite element model of RFA within Comsol Multiphysics software. This theoretical model has been used to simulate blood perfusion effects on resulting ablation volume. The effects from different large vessel blood flow parameters has been investigated, these parameters are: blood flow velocity, blood vessel diameter and distance between blood vessel and RF electrode. A factorial design has been utilised to setup parameter levels for the different simulations. A linear- and a second degree regression model has been calculated based on simulation results. The parameter with largest impact on simulative ablation volume and the interaction effects between the parameters were determined from the regression model coefficients. In addition to this has two simulations been performed, modelling perfused- and unperfused liver tissue, in order to investigate the effects resulting from microvascular perfusion.

    The result shows that the parameter with largest impact on simulative ablation volume are the distance, it was also shown that there are a small interactional effects between diameter and distance, where a small distance increases the effect from a varying diameter. Modelled microvascular perfusion was shown to give a decrease in simulative ablation volume. A shortage of this master thesis work is the lack of experimental verification of the developed model.

    Reuse of manufacturing experience in product and process definitions2008Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    Today's manufacturing industry faces hard competition, both in the form of competitor's low cost outsourcing and to reduce labour cost. Increased public consciousness for environmental pollution and stricter government legislation are also drivers for a more efficient product development process and companies competing on the global market must continue to improve there methods and tools to gain an advantage. The company's intellectual properties and the ability to capitalize on experience from earlier projects becomes a key factor when competing on the global market. This thesis work explores the mechanisms for knowledge reuse and suggests methods and tools involved in the product development process to improve the use of manufacturing experience in order to prevent manufacturing flaws to reoccur in new product development programs. The research is carried out in a project funded by the Swedish research agency VINNOVA together with the industry, through the MERA program. The project aims to improve the Digitally Linked Process and has a focus on Experience reuse. An initial research question was formulated to address the problem and guide the research towards a better understanding; "How can experience from manufacturing processes be tied and reused to impact the definition of governing product and process definition?" A study was set up to investigate the current practices and to aid the research in formulating an approach to improve methods and tools for Reuse of Manufacturing Experience (RoME). The study was conducted at two companies, one in the aerospace industry and one in the automobile industry. The "How" and "Why" questions supported a case study approach The study provided a better understanding of the problem and pointed at a number of opportunities to increase the use of manufacturing experience. One of the findings pointed out in the survey was the lack of a working process for preventing recurrence of a bad design in manufacturing. Furthermore, the study revealed a potential improvement in the use of capability data and problem reports that are captured and stored in databases, today more or less solely used in manufacturing. A new research question was formulized as the improvement of the RoME process where set in focus; "How can the process of experience reuse from manufacturing phases be improved to better impact earlier phases in product development?" The current process for finding and accessing process capability data from a Design Engineering perspective were investigated and described as well as the process to retrieve problem report notifications regarding specific design features of a component. The process where found to be both time consuming and tedious, and as a result of that, seldom used by design engineers. Key enablers having a significant impact on the RoME process where identified. The ability to find and access experience captured in the manufacturing phase. The ability to provide data in a context familiar for the receiver in order to facilitate the learning process. An improved process for reuse of manufacturing experience is proposed and includes methods and techniques to target system integration for search and access. A service oriented product life cycle management (PLM) architecture is proposed as a mean to address the topic of finding and accessing manufacturing data. The standard for PLM Services 2.0 provided by the Object Management Group (OMG) and the increased maturity of web service technology provide the possibility to integrate knowledge rich engineering application in a dispersed heterogeneous system environment. The ability to provide data in a context that is familiar to the receiver is addressed by developing a web based graphical user interface (GUI). The web based GUI presents the manufacturing data in a design context where manufacturing process capability data and problem report notifications are presented in a component view. This supports the design engineer when searching for relevant experience from earlier projects by associating the process capability data and problem reports to a specific design feature, e.g. a flange, and how it relate to the manufacturing process. A web based application is developed to demonstrate the concept. The application presents the product assembly (bill of material) together with the manufacturing process activities and corresponding process capability data in the same view, providing a contextual environment that is tailored for the receiver.

    Support for re-use of manufacturing experience in product development: from an aerospace perspective2011Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Globalization, public environmental concern and government legislation are challenging the Swedish industry to be more efficient and increase its efforts in research and in the development of methods and tools for product development and production. Furthermore, the manufacturing industry is changing from producing solely hardware products towards the inclusion of services or soft offers to add more value for the customer. As a result, there are an increased number of stakeholders involved in the early phases of product development that has an interest in the products design and performance during its life cycle. This challenges the way we manage and share experience internally as well as between companies.The intellectual property of a company is a key asset when competing on the global market; hence, the ability to capitalize on experiences from a company’s development processes as well as products in use becomes increasingly important. Also, the European manufacturing industry and the EU commission conclude that the industry has to move from being "Resource-based" to "Knowledge based" to add more value and avoid competing solely on low-cost. It is recognized that an expensive manufacturing solution has a negative effect on a products total life cycle cost and the ability to earn profit. Hence, manufacturing processes is constantly a target for improvement efforts and experience gained in manufacturing has a potentially high impact on design decisions in new projects.The aim of the research presented here is to improve manufacturability and avoid reoccurrence of design flaws in ongoing or new projects. The research has provided a better understanding of the mechanisms for experience re-use and developed methods and tools for feedback of experience from the manufacturing phase back to the earlier phases in the products life cycle. The work has been carried out within two projects funded by the Swedish governmental agency for Innovation Systems and industry. The first project was DLP-E, Digitally Linked Processes with a focus on Experience re-use and the second project was Robust Machining, aiming for more robust machining processes within manufacturing.The research approach has been to combine the design research methodology and participatory action research. These methodologies together with an initial research question have guided the work:RQ: “How can experience from manufacturing processes be tied and reused to impact the governing product and process definition?”Branches within engineering research committed to his area are concurrent engineering and design for manufacturing although this has usually been limited to general rules of thumb and qualitative methods for designers. Recently however, statistical methods such as Design for Six Sigma and other methods for Robust Design are introduced to affect earlier phases of PD to achieve improved manufacturability.Knowledge Based Engineering (KBE), represents a technology that provide the means to capture and automatically re-use engineering knowledge in an engineering design environment. Methods and tools from this area have been used as an initial approach in this research. A functional product perspective puts a focus on the activity where the product is used rather than on the tangible product itself. From an experience feedback perspective, experience is gained during these activities and possibly re-used if there is a learning process.This thesis presents an initial descriptive case study at two manufacturing companies that provided a better understanding of current practices for experience re-use and identified factors that influenced the feedback of manufacturing experience in product development. Based on initial assumptions and the results from the first descriptive study, a theory on the mechanism for experience feedback and requirements on a manufacturing system was formulated in a prescriptive study. A second descriptive study utilized a prototype to identify if the theory was applicable in an industrial environment and if it addressed the factors it was supposed to address. The research has been an iterative process, whereas results from the descriptive studies have influenced new prescriptive studies, delivering methods and tools, which in turn have influenced the ongoing work at the company where the research was conducted.The main contribution from the research is a framework to support re-use of manufacturing experience. The framework decompose the multifaceted task of experience re-use by identifying typical activities involved in the feedback process and categorizing the “elements of experience” in terms of knowledge, information and data. Combined with an engineering process improvement approach, processes are streamlined and value is added to the product. KBE techniques are used to capture and re-use product and process knowledge in an integrated manner. The applicability of the result has been validated in descriptive studies as well as within company improvement efforts.The research supports a frontloading approach in product development by enabling manufacturing experience to have an impact on the design definition in the early phases of product development. As a consequence, the risk for costly re-design later on in a project is reduced.

    A process improvement approach to capitalize on manufacturing experience in engineering design2009In: Design has never been this cool: ICED 09, the 17th International Conference on Engineering Design ; 24 - 27 August 2009, Stanford University, Stanford, California, USA ; proceedings volume / [ed] Margareta Norell Bergendahl, Gkasgow: Design Research Society, 2009, p. 287-298Conference paper (Refereed)
    Abstract [en]

    The ability to capitalize on company knowledge and experience earned in various projects is recognized as key assets in the competition on the growing global market. Methods and tools are constantly evolving, still there is a frustration over repeated design flaws and design engineers has a difficult task to find and use manufacturing experience from earlier projects. This paper outlines a process improvement approach where the engineering process is described andanalysed to find bottlenecks. Examples from other engineering processes are presented along with a prototype of a knowledge application to resolve identified issues with the manufacturing feedback process.Experience and knowledge are closely related, hence a knowledge life cycle explain the different stepswith a "capturing" and "deploying" side.The feedback processes for manufacturing experience is analysed where search & find together with contextualisation of experience data are recognised as key mechanisms. A knowledge application is presented that presents experience data from different repositories in a way that is logic for the receiver. This reduces the lead-time and increase the quality of the feedback process.

    Manufacturing system to support design concept and reuse of manufacturing experience2008In: Manufacturing systems and technologies for the new frontier: the 41st CIRP conference on manufacturing systems / [ed] Mamoru Mitsuishi; Kanji Ueda; Fumihiko Kimura, London: Encyclopedia of Global Archaeology/Springer Verlag, 2008, p. 137-140Conference paper (Refereed)
    Abstract [en]

    Life cycle responsibility for manufacturing companies increases the service content coupled to the product. One consequence is that transferring knowledge gained from all life cycle phases has an even more decisive impact on the definition of the product concept, here referred to as the functional product. The paper focuses on transferring experiences from the manufacturing phase and how to account for these in the design phase. Based on an empirical study at two companies, an automotive and one aeronautical company, current practices were identified. Manufacturing experiences are captured and managed in a manufacturing context whereas the use of experience in the design phase is discussed. Finally a generic approach to support the use life cycle experiences in earlier phases of product development is suggested, where the design and manufacturing case serves as an example.

    Reuse of manufacturing experience to support development of product/service systems2010In: Industrial product-service systems (IPS²): proceedings of the 2nd CIRP IPS² Conference [2010, Linköping, 14-15 April] / [ed] Tomohiko Sakao, Linköping: Linköping University Electronic Press, 2010Conference paper (Refereed)
    Abstract [en]

    The ability to learn from ongoing and previous projects is important for companies to become, and maintain, competitive. Hence efficient methods and tools for both capturing and reusing experience in all life cycle phases of the product is a key enabler to keep and gain an advantage in product development companies. By definition, PSS combines "features" applicable to different life cycle phases, e.g. reusability when disposed, serviceability in aftermarket, manufacturability in manufacturing, etc. The "total offer" must take into account all aspects and coherently map these into a receiver context to support the design engineer in his work. In particular - the design phase is important since both the products, its realization and accompanying services are to a large extent decided in the early phases. This paper presents an industrial case demonstrating the mapping and contextualization of manufacturing experience to provide engineers relevant context when defining and designing the PSS

    A case study of how knowledge based engineering tools support experience re-use2011In: Research into Design: Supporting Sustainable Product Development / [ed] Amaresh Chakrabarti, Bangalore, India: Research Publishing Services, 2011Conference paper (Refereed)
    Abstract [en]

    A manufacturing company’s unique intellectual capital is to a largeextent built on experience from its own product development andmanufacturing processes. Thus, methods and tools to utilize and benefit fromthis experience in an efficient way have an impact on a company’s ability tostay competitive and advance on the global market. Knowledge BasedEngineering (KBE) is an engineering methodology to capture engineeringknowledge systematically into the design system. Hence, KBE tools areconsidered to support experience re-use and improve engineering activities.This paper presents the results from a study where the objective was toinvestigate the support for experience re-use in KBE applications in anaerospace company. A proposed framework is presented to analyze thecapturing and use of experience in a company’s processes identifying gaps andpropose improvements. The study revealed weaknesses in the process steps forexperience feedback which can be used to improve KBE applications further.

    Project: Robust Machining2010Other (Other (popular science, discussion, etc.))
    Abstract [en]

    New generations of environmentally friendly and safe vehicles require manufacturing of light weight materials with higher strength and, as a consequence, tougher machining conditions and increased machining robustness. There is a lack of practical and reliable methods and tools to meet these challenges in the automotive industry. The very complex system of machine tool, fixture, cutting tools and the machined part is almost impossible to model without complementary measurements of the real system at the factory floor in full production. Using Virtual Engineering together with studies of machining processes the project team will assess these challenges.

    Lean implementation in the geriatric care sector in Sweden2015In: International Journal of Six Sigma and Competitive Advantage (IJSSCA), ISSN 1479-2494, E-ISSN 1479-2753, Vol. 9, no 1, p. 56-71Article in journal (Refereed)
    Abstract [en]

    The aim of this research is to examine how lean has been implemented in the geriatric care sector in a municipality in Sweden. The research focuses on implementation experiences and challenges encountered. The research method used is a case study using interviews and observations for data collection. The findings indicate that there are many advantages of lean in the geriatric care sector, such as better communication, organisation and workflow. The lean implementation worked as an eye-opener and created a situation, where the employees realised a great deal of waste in the daily operations. In addition, lean tools helped to reduce the waste. The findings also indicate that there are some challenges of lean in the geriatric care sector, such as the difficulty to create long-lasting lean commitment. A lack of follow-ups, decreasing interest from senior management and lack of a holistic view were the main issues in the case organisation.
