Therefore a consistent controlling of variants is difficult. This paper proposes the early use of the configurable bill of material [CBOM] to store and coordinate requirements and guidelines. It is demonstrated how requirements and guidelines regarding product and part variance can be translated in the boolean logic of the CBOM. The resulting continuous data can be used to implement a variety of controlling mechanisms.","PeriodicalId":235355,"journal":{"name":"DFX 2019: Proceedings of the 30th Symposium Design for X, 18-19 September 2019, Jesteburg, Germany","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127288837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The chosen scale levels are material. structure and product level and the model layers are reality. physical and virtual models. The challenges of the transferability of boundary conditions will be shown for three research topics. static testing for cylinders. optimization of sandwich inserts and dynamic testing of cabin interior.","PeriodicalId":235355,"journal":{"name":"DFX 2019: Proceedings of the 30th Symposium Design for X, 18-19 September 2019, Jesteburg, Germany","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126728725","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to lack of knowledge. no generalizable effect of the prototype fidelity is available yet. In the presented research project. a reduction approach is investigated with the aim to build up an understanding for the influences on the subjective suitability for use. and thus to enable an objective assessment.

As a result. an increased number of technical changes. known as variations in the PGE model. is observed at a late stage of develop-ment. This is accompanied by the question of what testing activities are neces-sary to verify or validate [V&V] these variations. The focus of the paper lies on the analysis of the G1 challenges.
