    On a methodology for component selection in modular branding: An industrial pilot study2014In: Concurrent Engineering - Research and Applications, ISSN 1063-293X, E-ISSN 1531-2003, Vol. 22, no 2, p. 93-105Article in journal (Refereed)
    Abstract [en]

    Performing modularization of a product family with multiple brands is a complex task that must integrate and balance a wide range of contradicting and ambiguous aspects, such as product performance, customer expectations, supplier alliances, and corporate business strategies. Furthermore, decisions on balancing these aspects that also change with time have to deal with a high degree of uncertainty. No general methodology for modular branding has currently been published. A methodology with that aim is proposed and prototyped in a real but anonymized industrial case. The presented task is to select standard original equipment manufacturer engines for six brands of self-propelled walk-behind lawn mowers. Selection is based on a set of calculated utility scores and known costs. The utility of an engine with a certain performance level and set of features is specific to each brand. This article presents a first step in developing a general methodology for modular branding and the organizational learnings of using the proposed methodology in an industrial setting.

    A holistic approach to concurrent engineering and its application to robotics2014In: Concurrent Engineering - Research and Applications, ISSN 1063-293X, E-ISSN 1531-2003, Vol. 22, no 1, p. 48-61Article in journal (Refereed)
    Abstract [en]

    This article details a holistic concurrent design framework, based on fuzzy logic, which is suitable for multidisciplinary systems. The methodology attempts to enhance communication and collaboration between different disciplines through introducing the universal notion of satisfaction and expressing the holistic behavior of multidisciplinary systems using the notion of energy. Throughout the design process, it uses fuzzy logic to formalize subjective aspects of design including the impact of the designer's attitude, resulting in the simplification of the multi-objective constrained optimization process. In the final phase, the methodology adjusts the designer's subjective attitude based on a holistic system performance by utilizing an energy-based model of multidisciplinary systems. The efficiency of the resulting design framework is illustrated by improving the design of a 5-degree-of-freedom industrial robot manipulator. © The Author(s) 2013.

    An integrated design evaluation system supporting thermal-structural iterations1998In: Concurrent Engineering - Research and Applications, ISSN 1063-293X, E-ISSN 1531-2003, Vol. 6, no 3, p. 179-187Article in journal (Refereed)
    Abstract [en]

    In the design of high temperature components, design evaluation often requires an iterative procedure between thermal fluid and thermal structural simulations An integrated computer system providing an iterative environment for the multidisciplinary simulations re quired has been developed. The system supports iterations between thermal fluid and thermal structural simulations using two different commercial simulation packages. Traditionally, fluid and structural analysis have been simulated separately and analysis of coupled prob lems has required special, multidisciplinary simulation packages which are seldom used in early stages of design. Improving the infrastruc ture for data exchange between separate computer applications is one way to significantly reduce the lead time for design iterations. This reduction in lead-time allows multidisciplinary effects to be accounted for in early stages of design. The design system is demonstrated on an exhaust manifold, where the thermal interaction between fluid and structure is of significant importance. The commercial simulation tools have been integrated to demonstrate the effect of automised data flow on design methodology, i.e , de sign iterations. This integration method makes use of existing features in the simulation packages and uses an export file format as the neu tral exchange format. In this way, the integrated system is simple and fast to develop which is preferred in small prototype systems and de velopment project Database integration supports a tighter integration, but requires more development effort. For design systems, where several design tools need to communicate, standardised information management procedures are preferable, following the ideas of the STEP framework.

    Categorisation of geometry users2001In: Concurrent Engineering - Research and Applications, ISSN 1063-293X, E-ISSN 1531-2003, Vol. 9, no 1, p. 15-23Article in journal (Refereed)
    Abstract [en]

    Many companies today use 3D geometry-based product models in engineering design. 3D-models are used from early development stages and stored in CAD databases. They should be regarded as a resource for elimination of rework in downstream activities of the extended enterprise. In order to increase the usage of this already acquired information, complements to existing business processes must take place. The result will contribute to increased integration of the development process and therefore more concurrent engineering. The paper addresses the way in which requirements on Geometry Based Product Information (GBPI) should be decomposed. The decomposition makes it possible to separate and categorise geometry users. The presented methodology is a complement to existing business processes. It makes it possible to map corporate requirements on GBPI, and thus to address these categories in the product development process's different stages. The proposed method is based on key principals of Quality Functions De ployment. The data for the work has been collected from a survey conducted at the Volvo Truck Corporation in Sweden.

    Integrated design and verification system for finite element modelling1993In: Concurrent Engineering - Research and Applications, ISSN 1063-293X, E-ISSN 1531-2003, Vol. 1, no 4, p. 213-217Article in journal (Refereed)
    Abstract [en]

    This paper presents a computer-integrated system for design, manufacturing simulation, and inspection using a coordinate measurement machine (CMM). The work is concerned with the problem of predicting the shape of the container for hot isostatic pressing (HIP) and it focuses on the verification of a finite element (FE) simulation model for HIP. The verification is performed by comparing the simulated geometry of a real component produced by HIP. The geometry of the HIP component is measured by a CMM. The whole process from design and manufactunng simulation to inspection and geometry verification is performed within a computer-aided concurrent engineering (CACE) system. The system is built on both commercial and non-commercial software. The communication between a CMM, a geometnc modelling system, and the finite element simulation codes is developed. The manufacturing of a turbine component to net shape geometry using HIP is chosen as a demonstrator example. The benefits of the presented CACE system are time and cost savings as well as higher product quality.

    Development of product platforms: Theory and methodology2017In: Concurrent Engineering - Research and Applications, ISSN 1063-293X, E-ISSN 1531-2003, Vol. 25, no 3, p. 195-211Article in journal (Refereed)
    Abstract [en]

    There is a trend toward increased customization of goods to satisfy a wide range of customers using product platforms. However, there is an erroneous notion that product platforms can only be used to provide economic viability in production thanks to the reuse of physical components among a family of products. Yet, this is a limited perception of the potential of a product platform. In this article, an object-oriented approach to support the development of product platforms is proposed to increase efficiency through reuse and flexibility of designs among a family of products. Two modes of the platform development process are addressed: platform preparation and platform execution. Platform preparation prescribes the methods needed to model platform objects, using enhanced function-means models and set-based concurrent engineering processes. During the platform execution process, sets of design alternatives can be configured concurrently throughout the conceptual, system, and detailed phases of the platform development. Three cases illustrate how the same approach may be used in different design scenarios: design space exploration and extension, supply-chain collaboration, and configure-to-order. The approach supports system architects and design engineers in making design decisions that propel the platform development work by enabling analysis in stages where designs are immature and evaluating the goodness of the alternatives early. Ultimately, product platforms can be efficiently developed for modularity and scalability to find feasible product variants and meet the needs of a multitude of customers.

    Collaborative multidisciplinary design optimization: A framework applied on aircraft conceptual system design2015In: Concurrent Engineering - Research and Applications, ISSN 1063-293X, E-ISSN 1531-2003, Vol. 23, no 3, p. 236-249Article in journal (Refereed)
    Abstract [en]

    In a product development process, it is crucial to understand and evaluate multiple and synergic aspects of systems such as performance, cost, reliability, and safety. These aspects are mainly considered during later stages of the design process. However, in order to improve the foundations for decision-making, this article presents methods that are intended to increase the engineering knowledge in the early design phases. In complex products, different systems from a multitude of engineering disciplines have to work tightly together. Collaborative design is described as a process where a product is designed through the collective and joint efforts of domain experts. A collaborative multidisciplinary design optimization process is therefore proposed in the conceptual design phase in order to increase the likelihood of more accurate decisions being taken early on. The performance of the presented framework is demonstrated in an industrial application to design aircraft systems in the conceptual phase.

    Implementation of collaborative multidisciplinary design optimization for conceptual design of a complex engineering product2016In: Concurrent Engineering - Research and Applications, ISSN 1063-293X, E-ISSN 1531-2003, Vol. 24, no 3, p. 251-265Article in journal (Refereed)
    Abstract [en]

    This study investigates the performance of the collaborative multidisciplinary design optimization framework and how it facilitates the knowledge integration process. The framework is used to design and optimize an innovative concept of a tidal water power plant. The case study helps to highlight the challenges that may occur during implementation. The result is presented as a modified framework with less implementation difficulties. The improved framework shows significant reduction in design time and improvement in collaborative design optimization for a design team. The geometry of the product is optimized to minimize weight and maximize the power generated by the turbine with respect to some mechanical constraints.

    Functional product life-cycle simulation model for cost estimation in conceptual design of jet engine components2005In: Concurrent Engineering - Research and Applications, ISSN 1063-293X, E-ISSN 1531-2003, ISSN 1531-2003, Vol. 13, no 4, p. 331-342Article in journal (Refereed)
    Abstract [en]

    As functional (total care) products emerge in the jet engine industry, the need for product life-cycle models capable of definition and evaluation of life cycle properties increases, since functional products (FP) includes both hardware and service. Recent life-cycle models are intended for hardware products and mostly handle design and manufacturing knowledge. The aim of this article is to present a design approach that extends the evaluation capabilities beyond classical hardware design and manufacturing evaluation. The focus has been to introduce evaluation of manufacturing and post-manufacturing activities in evaluation of conceptual designs. For this purpose, a model has been proposed to handle the information flow between teams when developing structural jet engine components. A case study, in which the proposed model was used in cooperation with a jet engine component manufacturer, is presented. Aspects concerning design, manufacturing, performance, and maintenance of jet engine flanges were included in the example by means of a knowledge based engineering (KBE)-system coupled to databases and spreadsheets. The model is more suitable than recent work for the development of hardware parts of functional products (HFP), since knowledge from more product development disciplines is included. As the engineer changes the design and directly assesses the life-cycle cost (LCC) and how the changes impact the interface to other jet engine components, more knowledge on the impact of design decisions is available at hand for the engineering designer than without the model

    A knowledge-based master-model approach with application to rotating machinery design2011In: Concurrent Engineering - Research and Applications, ISSN 1063-293X, E-ISSN 1531-2003, Vol. 19, no 4, p. 295-305Article in journal (Refereed)
    Abstract [en]

    Novel rotating machinery design concepts and architectures are being explored to reduce mass, energy consumption, manufacturing costs, and environmental impact while increasing performance. As component manufacturers supply parts to original equipment manufacturers, it is desirable to design the components using a systems approach so that they are optimized for system-level performance. To accomplish that, suppliers must be able to model and predict the behavior of the whole machinery. Traditional computer-aided design/computer-aided engineering master-modeling approaches enable manual changes to be propagated to linked models. Novel knowledge-based master-modeling approaches enable automated coordination of multidisciplinary analyses. In this article, we present a specific implementation of such a knowledge-based master-modeling approach that facilitates multidisciplinary design optimization of rotating machinery. The master-model (MM) approach promotes the existence of a single governing version of the product definition as well as operating scenarios. Rules, scripts, and macros link the MM to domain-specific models. A simple yet illustrative industry application is presented, where rotor-dynamics and displacement analyses are performed to evaluate relocation alternatives for the rear bearing position of a rotating machinery under a ‘fan-blade-off’ load case.
