Item type:Publication, Access status: without files , Efficient application of MBSE using reference models: a PGE case study(Curran Associates, Inc., 2017-08); ; ; ; Product engineering has become more and more complex, as there are multiple interrelated elements with high dynamic and variance. To support the work of designers and managers, various methodologies have been proposed in the literature. In this paper, it shall be evaluated how the reuse of information stored in reference models can improve the approach of model-based systems engineering to add value in the design process. Therefore a case study is conducted in the battery development department of the AVL List GmbH. A detailed and quantified evaluation of problems caused by complexity is used to derive specific solutions based on the usage of reference models in a model-based approach. Through this approach a reduction of unnecessary effort by 60 % is estimated showing how the usage of reference models adds value in the design process and is a relevant foundation of methodology development.Publicationtype: Conference Paper61 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Discursive vs. intuitive - An experimental study to facilitate the use of design cataloguesThough shown to be of support to the designer, design method acceptance is still an issue to the design society today. Requirements and concepts in general derived from fundamental learning principles have been developed to enhance learning. This study is an experimental study to collect impressions about design method acceptance based on predefined criteria for facilitated use of design catalogues. Two workshops in sequence were conducted with students of advanced integrated product development courses to teach and train them in design catalogues. The control group applied twice a discursive solution finding process with design catalogues whereas the test group first worked intuitively with the brainstorming method and just in the second stage with a discursive solution finding process. Results have shown differences in the perception of both groups and revealed an improved method acceptance for groups who worked discursively twice. The groups working intuitively first and then discursively claimed that the design catalogues rather restricted their creativity but were considered useful as an additional tool. Implications for enhancing the learning experience could be deduced.Publicationtype: Conference Paper101 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Towards an impact model of modular product structures(2017-08); Modularization of product families affects firms in many ways. Many of them have been investigated in research and observed in industry. But which effect will most likely occur, by which kind of modular product structure it can be achieved and how this product structure affects other life phases is often not clear because the understanding for the whole system of product structures and effects is missing. The aim of this paper is to show the interrelations between product structures and the effects they entail. Hence it provides the desired system view. For the model development the properties and characteristics are defined to be able to differentiate product family structures. For collection of the effects a literature study was undertaken, the effects and their product structural causes are investigated and displayed in a flow chart based visualization, which is divided into product life phases. The value of the paper lies in the provision of a visual model including product structural cause and its life phase effects on a firm which has been missing in literature and is important for decision-making.Publicationtype: Conference Paper92 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Cost based design of modular product families using the example of test rigs(2017-08); ; Companies with a wide range of variety on the markets have to reduce their internal variety for reducing their costs. This can be reached through modular product families, where more than one concept is possible. A decision making based on costs is missing for the choice of the developed concepts. In this Paper an approach for developing modular product structure concepts based on cost is presented. Based on literature review the Integrated PKT-Approach for developing modular product families is adapted for analyze cost, process and product structure for developing and cost prognosis of concepts and modified tools for analyzing cost are explained. This approach is used in a case study for an industry company where three cost-efficient variety optimized concepts were developed. The approach is helpful for developing cost-reduced concepts based on cost analyses and gives a cost prognosis for rating the concepts.Publicationtype: Conference Paper81
