    Future Logistical Services from Connected Vehicles: A Case Study at Scania CV AB2017Självständigt arbete på avancerad nivå (yrkesexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    The road based transportation operations are growing rapidly, but the current infrastructure cannot sustain the entire growth. At the same time vehicle utilisation and fill rates are low. Improved efficiency of the operations is a necessary way forward for road based transportation. Parallel to this, heavy vehicle producers are currently improving the efficiency with services accompanying the product that are focused on the driver and the vehicle performance. However, the data from connected vehicles required for these services only entail a small amount of the operational data generated by connected vehicles. The case study aims to answer how to use connected vehicle operational data in order to suggest value adding services in a dynamic road distribution system. The applied methodology is an inductive study with an explanatory approach to map the current and future service offerings of the case company. This knowledge is combined with an exploratory approach with interviews of transport planners and theories of Lean and fleet management. Primarily, it is concluded that the perspective of operational data requires widening. Considering not only driver and vehicle operations but rather the entire transport operation of a company. It is also concluded that value creation with operational data is possible during three phases of fleet management. First, if knowledge about order data is accessible, the planning of transportations can be improved using route optimisation and operations research. Secondly, it is possible to create value during the execution phase, throughless manual supervision and communication by transport planners. Lastly, both the currently used operational data and further data usage can contribute to a better understanding of the performance of a fleet operation and facilitate for continuous improvements during an evaluation phase.

    Principalansvaret för vårdnadshavare: Föräldrars skadeståndsansvar för skada vållad av barn2016Självständigt arbete på grundnivå (kandidatexamen), 180 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Personer under 15 år kan inte straffrättsligt bli ansvariga för brott de begått i enlighet med 1 kap 6§ BrB. Däremot kan en civilrättslig process gällande skadeståndsrättsligt anspråk bli aktuell i princip oberoende av skadevållarens ålder. Huvudregeln är alltså att barn kan bli skadeståndsskyldiga på samma sätt som en vuxen om de anses ha vållat skada. De större utmärkande skillnaderna mellan att hålla ett barn jämfört med en vuxen skadeståndsskyldig är att det görs en så kallad skälighetsbedömning när det gäller barn och även vid bedömning av barns culpa tar man mindre hänsyn till de subjektiva kriterierna. I denna uppsats utreds vårdnadshavarens ansvar enligt 3 kap. 5§ skadeståndslagen som infördes år 2010. Denna reglering innebär att föräldrar kan blir skadeståndsansvariga för skador som deras barn orsakar genom brott samt genom tillsynsansvaret som regleras i 6 kap. 2§ föräldrabalken. Denna paragraf reglerar att vårdnadshavaren skall ge barnet den tillsyn och uppsikt det behöver medhänsyn till ålder, utveckling och övriga omständigheter för att hindra skadevållande handlingar. Skillnaden mellan dessa respektive lagregler gällande att vårdnadshavaren skall anses vara skadeståndsansvarig är att den förra förutsätter att barnet begått ett brott och förutsätter heller ej culpa medan den senare inte gör det.

    Assessment of risk factors and the prevalence of musculoskeletal disorders by QEC and Body Map operational units of the gas refinery in Iran and its Meta-Reflection2016Ingår i: Journal of Health, ISSN 2382-9710, Vol. 7, nr 1, s. 35-50, artikel-id 7Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Introduction: This study aims to evaluate the risk factors and the prevalence of WMSDs disorders using QEC and Body Map techniques in operational units took a gas refineries and its Meta-Reflection.Method and Material: This case study assessed 254 operators in three distinct phases. First, 72 workstation posture was evaluated by using of QEC. Secondly was intended for employees of WMSDs were assessed using by Body Map. After conducting interview with relevant directors, the effectiveness of such studies has been analyzed through Meta-Reflection.Results: Based on results came from QEC survey, the operators’ average scores was %53/8. Moreover, results of Body Map assessment showed that the highest organs of WMSDs were back and knee extrusions (47% and 46% respectively). Also, lack of ergonomics policy and plan within refinery has demonstrated by interviews. Meta-Reflection, on the other hand, showed that because of incomplete learning cycles in the mentioned surveys which only provide WMSDs’ status, workstations’ ergonomics condition, and introduce expert based solutions. Thus, such surveys not only have incomplete study plan, but also have less impact on improving overall health, safety and ergonomics within this organization.Conclusion: This research proves that non-ergonomic conditions result in awkward postures and subsequent physical disorders. Overall, this study has showed a gap from this kind of the work on the learning cycles at organizational levels, a trend should be considered to interactive research work on the workplaces with improved and promoted system ergonomics attitude.

    Enhanced Oil Recovery (EOR) as a Stepping Stone to Carbon Capture and Sequestration (CCS)2018Ingår i: Mineral Economics, ISSN 2191-2203, E-ISSN 2191-2211, Vol. 31, nr 1-2, s. 239-251Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Environmental concerns about carbon emissions coupled with the oil industry’s need to secure additional CO2 for enhanced oil recovery (CO2-EOR) projects have sparked interest in the potential that CO2-EOR may have in jumpstarting carbon capture and sequestration (CCS). However, existing studies on the viability of coupling CO2-EOR with CCS have generally placed more focus on either the engineering or economic aspects of the problem. Most engineering studies focus on the technical aspects of the CO2-EOR project to produce the maximum amount of oil, while simultaneously storing the most CO2 during the production process with the economics as an afterthought, while most economic studies found have focused on a singular aspect of the issue such as impacts of exogenously varying injection rates. Furthermore, modelling efforts have stopped at the end of the productive life of the field. We build a unique two-stage dynamic optimization model, which simultaneously addresses engineering and economic policy aspects, to study the viability of coupling CO2-EOR transitioning into CCS. Our model includes a carbon tax for emissions, which becomes a subsidy for full scale sequestration after oil production has ceased; this allows us to explore the transition from CO2-EOR, our first stage, to sole CO2 sequestration in our second stage for a single field. We maximize the operator’s profits across both stages, while tracking the responsiveness of oil production and total carbon movements to both price and policy changes. We pair our optimization model with a reservoir simulation model, allowing us to mimic actual field behavior, giving our work a more realistic representation of both production and sequestration profiles. Our results suggest that small increases in the level of carbon tax can have large and discontinuous impacts on net sequestration. This stems from the observed transition from limited natural sources of CO2 to more expensive captured CO2 resulting from the implemented policy. With appropriate taxes, total volumes of captured CO2 sequestered across both stages are equivalent to 30 to 40% of the emissions from the use of the oil produced. With the credits oil producers receive from sequestering CO2, which equate to the tax, relatively high carbon taxes incentivize additional sequestration without significantly impacting the supply of oil. This, alongside maintaining a steady stream of profits, is a win-win situation for energy security and the climate.

    A new heuristic to solve the one-warehouse N-retailer problem2010Ingår i: Computers & Operations Research, ISSN 0305-0548, E-ISSN 1873-765X, Vol. 37, nr 2, s. 265-272Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We deal with a multi-echelon inventory system in which one warehouse supplies an item to multiple retailers. Customer demand arrives at each retailer at a constant rate. The retailers replenish their inventories from the warehouse that in turn orders from an outside supplier. It is assumed that shortages are not allowed and lead times are negligible. The goal is to determine replenishment policies that minimize the overall cost in the system. We develop a heuristic to compute efficient policies, which also can easily be used in a spreadsheet application. The main idea consists of finding a balance between the replenishment and the inventory holding costs at each installation. This new heuristic we compare with two other approaches proposed in the literature; the computational studies show that in most of the instances generated the new method provides lower costs.

    Priming vid ordstamskomplettering2020Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Priming är ett sätt att studera hur det implicita minnet fungerar och påverkar oss. I den här studien undersöktes priming vid ordstamskomplettering och hur presenterat ord respektive icke presenterat ord påverkar priming. Syftet med studien var att undersöka och analysera priming vid ordstamskomplettering. Frågeställningen i studien har varit: Vilken inverkan har ett presenterat respektive icke presenterat ord vid priming? Hypotesen var att deltagarna skulle komplettera fler ord från den lista som de har sett än från den lista som de inte har sett. Tolv deltagare var med i studien mellan åldrarna 21 och 28 år. Resultatet från experimentet stödjer hypotesen. SPSS paired samples analysis visade att resultatet var signifikant, vilket stödjer hypotesen att det uppstår priming vid ordstamskomplettering.

    Adaptation to discomfort in personal protective devices: an example with safety helmets1990Ingår i: Ergonomics, ISSN 0014-0139, E-ISSN 1366-5847, Vol. 33, nr 2, s. 137-145Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Discomfort in the use of personal protective devices (PPD) has been one of the chief causes of their non-use. A field trial using industrial helmets was carried out to ascertain whether by training and repeated wearing subjects could experience a significant adaptation to discomfort. Ten subjects took part in the trial in a tropical environment by wearing helmets repeatedly (6 h a day) for one month. Subjective evaluations of discomfort were made at the end of the 1st, 3rd, 5th, 14th and 30th day. It was revealed that complaints of discomfort, viz. hotness, heaviness, bad fit, etc., decreased markedly throughout the 30 day period. Though positive responses of adaptation to discomfort seem to reach an optimum towards 30 days, it is difficult to draw any conclusions on the optimum period of adaptation for each discomfort factor. In relation to inherent discomforts that are extremely difficult to overcome without compromising the protection efficiency of a PPD, the principle of adaptation seems to be a very important facet which has to be developed for an effective PPD programme.

    A head-model reconstruction based upon photogrammetric data from Sri Lankan adult males relevant to the design of headgear1989Ingår i: Journal of Human Ergology, ISSN 0300-8134, Vol. 18, nr 2, s. 199-211Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Due to the large variability in heads and faces in one population, the standard anthropometric dimensions of the head, measured from anatomical landmarks alone, may not suffice for the design of fitting headgear, e.g., helmets. To provide adequate data of the shapes and contours of the head to the designer, appropriate head models sculptured using comprehensive head dimensions, must be developed. This paper describes (a) a procedure of collecting comprehensive anthropometric data of the head using a photogrammetric method and (b) a simple sculpturing technique to reconstruct a head model of the user population

    Body size variability between people in developed and developing countries and its impact on the use of imported goods1989Ingår i: International Journal of Industrial Ergonomics, ISSN 0169-8141, E-ISSN 1872-8219, Vol. 4, nr 2, s. 139-149Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The Industrially Developing Countries (IDC) today, to a great extent, depend on Industrialized Countries (IC) for the supply of most industrial goods. An attempt has been made to ascertain the degree of design incompatibility experienced by users of these imported goods due to differences in the body sizes of people in producer and user countries. A comparative study of variations in body sizes is made from data available in literature and from anthropometric surveys. The results reveal differences in almost every part of the human body. The need for reliable anthropometric data in respect of IDC is stressed. Urgent measures are required to introduce changes in equipment, particularly for the benefit of users in IDC.

    Ergonomics assessment of selected dust respirators: their use in the tropics1987Ingår i: Applied Ergonomics, ISSN 0003-6870, E-ISSN 1872-9126, Vol. 18, nr 4, s. 266-272Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The suitability and effectiveness of four different types of British made respirators were studied with respect to comfort, convenience and fit on wearers in Sri Lanka (a developing country). Objective and subjective assessments were made to evaluate the degree of discomfort and interferences to the use of senses. The study revealed that factors such as breathing resistance, work-rate and activity period affected the physiological responses. The weight of the respirator and the skin temperature had no direct relationship with the cardiovascular stress. Positive-pressure respirators that gave lower face temperatures than negative-pressure masks gave this type of respirator an additional advantage in hot environments. Respirators that restricted jaw movement affected the speech intelligibility of the wearer. Orinasal masks restricted vision more than the other types. The problem of fit was found negligible though head and face dimensions significantly differed between the British and the Sri Lankans. Subjective assessment correlated well with objective tests.

    Ergonomics evaluation of modified industrial helmets for use in tropical environments1988Ingår i: Ergonomics, ISSN 0014-0139, E-ISSN 1366-5847, Vol. 31, nr 9, s. 1317-1329Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Hotness, weight, fitting problems etc., have been found to be the chief causes of the unpopularity of industrial safety helmets in tropical environments in developing countries (DC). Some selected safety helmets manufactured in industrialized countries (IC) were modified to provide extra head ventilation and to reduce weight, in order to make them more acceptable to users in hot environments. The modified helmets were subjected to ergonomics evaluation both objectively and subjectively in the laboratory (in simulated tropical conditions) as well as in the field situation. There was evidence that white helmets had some advantages in comfort, viz. reduction of hotness, compared to the other colours, e.g. red, green etc., when worn in the presence of radiant heat in the laboratory. Ventilation holes provided at the top of the shell seemed to reduce the greenhouse effect within the helmet shell which therefore felt less uncomfortable than a fully covered helmet. Even with a small reduction of weight, such as 45 g in helmets weighing about 350g, the difference in weight was perceived by the wearers. In adapting helmets made in IC for use in tropical climates, head ventilation and low weight perception are important aspects in comfort which need to be considered. In addition to low cost, a harness material suitable for sweat absorption is required. Adjustability and sizing to fit 90% of the user population also needs to be considered in the design and manufacture of safety helmets for people in DC.

    Ergonomics of technology transfer1987Ingår i: International Journal of Industrial Ergonomics, ISSN 0169-8141, E-ISSN 1872-8219, Vol. 1, nr 4, s. 265-272Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    It is beyond doubt that high technology has elevated the standards of living of mankind. The modern technology created and developed to a great extent by Western or developed societies is now in great demand in Eastern and developing societies who are trying to leap-frog towards advancement. But unfortunately, in the transfer of technology, both the giver and the receiver seem to make many mistakes. A technology transferred without considering the ethnic variables in the societies and differences in the climates, has found to cause problems to the acquirer. Due to the basic human factor differences such as sizes of people, physical environment, physical capacities and organizational and cultural differences, a technology which is unadapted has found to be inappropriate, harmful, hazardous and unsuccessful. In the areas of health, working conditions, production and finance, undesirable effects have resulted through haphazard technology transfer, For a successful transfer, it is therefore stressed that technology has to be adapted or modified taking into consideration the technological, anthropological and socio-economic factors of the acquiring population

    Större möjlighet till jämförbarhet inom företag än företag emellan: En kvalitativ studie med 59 unika observationer av svenska företags hållbarhetsrapporter, ur en miljöaspekt2020Självständigt arbete på avancerad nivå (yrkesexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    The purpose of this study was to create understanding for how comparable sustainability reports are. The study has focused on the environmental aspect within the Swedish industry of clothing, footwear and wholesale. A content analysis has been executed, with a selection of 73 companies. After a shortfall there remained 21 companies and the study has performed 59 unique observations. The authors have developed a model to systemize the information collected in the content analysis. The study’s model focuses on four factors that affects the comparability of the sustainability reports. The four factors are guidelines, environmental indicators, measurements and absolute and relative numbers. The study emanated from the stakeholder and legitimacy theory. The theories say that companies should treat their stakeholders equally and that they should sustain a social contract with the community that creates legitimacy.

     

    The study showed that sustainability reports have a relatively high comparability within the companies. The Companies tend to report the same environmental indicators from year to year, which contributes to the comparability within the company. The comparability between companies is slightly lower, which is due to companies reporting information that is considered relevant for their own operations. This results in differences between companies in which environmental indicators are being reported as well as which measurements are used, this affects the comparability negatively.
