    State of the art in simulation driven design2013Ingår i: International Journal of Product Development, ISSN 1477-9056, E-ISSN 1741-8178, Vol. 18, nr 1, s. 68-87Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    During the last few decades, and in order to increase product development efficiency, simulations strategies have been developed to guide designers towards better solutions rather than to verify suggested and basically unevaluated solutions. Such approaches are often called Simulation Driven Design (SDD), which is of interest in this review. The objective of this paper is to show the research evolution of SDD and identify the state of the art in SDD methodology. The literature review comprises several hundred references, of which 79 are included in this paper. The results comprise the state of the art in simulation driven design including the history, various definitions, criteria and effects of using SDD approaches.

    Integrated Capture and Representation of Product Information In Computer-Aided Product Development2015Ingår i: ASME 2015 International Design Engineering Technical Conferences and Computers and Information in Engineering Conference: August 2-5, 2015, Boston, Massachusetts, USA., New York: American Society of Mechanical Engineers , 2015, Vol. 1B, artikel-id DETC2015-47299Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper features the implementation and evaluation of a proposed approach for information capture and representation integrated into the existing design environments at two manufacturing companies. A tool has been developed that automatically derives information from the CAD system during design and provides users with the means to capture product information that has previously been documented outside of the CAD system. Product information is managed in a PLM data model and becomes, once stored, the foundation for providing tailored views of information.Feedback from the evaluation shows that the prescribed approach was preferred to the current one and that it would likely provide value to users, both authors and consumers, of product information. This approach can reduce the time required to capture the pertinent product information. However, the primary savings are likely to be indirect as a result of increased consistency, understanding, and the potential (re)use of product information.The approach and tools presented constitute another step toward providing each stakeholder with more efficient, intuitive, contextual, and purposeful support for information capture and representation in computer-aided product development.

    Abstract [en]

    The amount of product and process related information in the engineering industry is large and constantly growing. Methods and tools are therefore needed to effectively leverage the information, ensuring that it is readily available, contextually understandable and usable for the activity at hand. This paper presents findings from two cases performed at manufacturing companies and an approach for how information effectively can be utilized during the development and lifecycle of a product. The approach primarily addresses the lack of up-to-date information, free of redundancies and accessible from the context where it is needed or will be captured.

    Knowledge retention and reuse: supporting engineering decisions in simulation-driven product development2012Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Information exchange is becoming more and more important as modern manufacturers increasingly rely on integrated product development. Research shows that designers may not be aware of existing information or be willing to disrupt their work to search for the relevant information. One part of the answer to issues related to understanding, availability and actual consideration is context. The research trend in knowledge sharing seems to be moving towards integration of additional platform-independent applications and lightweight product representations to accommodate contextual communication, even though findings suggest user reservation to additional applications. The part Computer Aided Design and Engineering systems play in the product lifecycle however continues to expand, as is the concept of Simulation-Driven Design as a means of ensuring downstream product lifecycle consideration. The underlying purpose of the research presented in this thesis is essentially to, enable and ensure awareness, access and understanding of product and process related information, for relevant actors, during relevant activities and within relevant environments.The proposed approach serves to enable, and to an extent ensure, contextual decision support within the early stages of product development, thus increasing the foundation for continued understanding and overall development. The approach has been implemented, and the resulting demonstrator includes but a few examples of how heavyweight technologies can, and to an extent should be used to ensure a better foundation for design decisions. The presented approach is a general way of not only enabling Simulation-Driven Design capabilities, but ensuring that they in fact have the desired impact. Investigations and demonstrator evaluations show that access to supporting tools and relevant information has to be made readily and contextually available. These have to be intuitive, integrated into the environment where they are needed, and ultimately be perceived as a natural part of daily development in order for them to be accepted and used. It is important to realise that the tools themselves are no cure-alls, nor are they replacements for purposeful communication and conscious consideration to all aspects of the product lifecycle. Still, transparency and an educational approach to tool development could be a catalyst, an entry point towards ensuring insight and understanding, so that each actor in turn can act with consideration to the product lifecycle as a whole, instead of just the task at hand.

    Efficient design module capture and representation for product family reuse2017Ingår i: Journal of Computing and Information Science in Engineering, ISSN 1530-9827, E-ISSN 1944-7078, Vol. 17, nr 3, artikel-id 031002Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    New business models and more integrated product development processes require designers to make use of knowledge more efficiently. Capture and reuse are means of coping, but support, techniques, and mechanisms have yet to be sufficiently addressed. This paper consequently explores how computer-aided technologies (CAx) and a computer-aided design (CAD) model-oriented approach can be used to improve the efficiency of design module capture and representation for product family reuse. The first contribution of this paper is the investigation performed at a Swedish manufacturing company and a set of identified challenges related to design capture and representation for reuse in product family development. The second contribution is a demonstrated and evaluated set of systems and tools, which exemplifies how these challenges can be approached. Efficient design capture is achieved by a combination of automated and simplified design capture, derived from the design implementation (CAD model definition) to the extent possible. Different design representations can then be accessed by the designer using the CAD-internal tool interface. A web application is an example of more generalpurpose representation to tailor design content, all of which is managed by a product lifecycle management (PLM) system. Design capture is based on a modular view block definition, stored in formal information models, management by a PLM system, for consistent and reliable design content. It was, however, introduced to support the rich and expressive forms of capture and representation required to facilitate understanding, use, and reuse of varied and increasingly complex designs. A key element in being able to describe a complex design and its implementation has been capture and representation of a set of design states. The solution has been demonstrated to effectively be able to capture and represent significant portions of a step-by-step design training material and the implementation of complex design module through a set of design decisions taken. The validity and relevance of the proposed solution is strengthened by the level of acceptance and perceived value from experienced users, together with the fact that the company is implementing parts of it today

    Abstract [en]

    In order to ensure competitive advantage, manufacturers need to reduce the time and resources spent on development without affecting the quality and performance of the final product. Studies show that designers are likely to change both job and company several times during their career. The loss of experience and expertise implies that new methods for efficient knowledge retention and reuse need to be developed. Results presented in this paper include development and implementation of a previously proposed method suggesting the use of CAD models as carriers of knowledge. The method has been further developed and realised in a three-part demonstrator, each part addressing one aspect of a holistic approach to efficient knowledge retention and reuse. The approach presented here does not require the use of any additional applications during product development and it ensures that the designer has access to necessary information, where and when it is needed. This approach also results in less time spent on documentation, data conversion and information retrieval.

    Supporting engineering decisions through contextual, model-oriented communication and knowledge-based engineering in simulation driven product development: an automotive case study2013Ingår i: Journal of engineering design (Print), ISSN 0954-4828, E-ISSN 1466-1837, Vol. 24, nr 1, s. 45-63Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Modern manufacturers rely increasingly on overlapping activities and frequent, bilateral exchange of preliminary information, adding to the complexity of information exchange and general reuse. The approach presented in this paper relies on a reuse process, embedded in the design environment already used, to avoid disrupting the design process and to increase the foundation upon which decisions are made. The proposed approach relies on Knowledge Based Extensions to commercial CAE systems and 3D CAE models to enable and ensure Simulation Driven Design capabilities and contextual communication within the early stages of product development. The approach has been shown to increase the simulation-driven capabilities in a business-to-business scenario, and in extension, increase the foundation upon which decisions are made and the likelihood of reaching a feasible and optimal final design. In conclusion, a simulation-driven design approach to product development has to be more than enabled to truly make a difference in the development process. Investigation and evaluations show that supporting tools and relevant information must be made readily available, intuitive, integrated into the environment where they are needed and, ultimately, be perceived as a natural part of daily development in order for them to be accepted and used.
