Alternative powertrains, automated driving and Vehicle-to-Everything (V2X)-communication impose new requirements for vehicle development. Automotive software (SW), hardware (HW) and Vehicle Electronics combined in Electrical/Electronic architectures (E/E-architectures) play a key role in the paradigm change. An evolution from function-oriented, distributed architectures towards domain-or even vehicle-centralized architectures is expected. Even so, the question of evaluating architecture alternatives based on quality characteristics is unsolved. Then again, measuring an E/E-architecture’s quality and suitability is necessary for developing appropriate, use case specific solutions to support a sustainable transformation. By designing a method to evaluate design alternatives for the E/E-architecture of vehicles, combining different viewpoints and evaluation metrics, a contribution to this transformation can be provided. In this work such a viewpoint-based architecture framework enabling a holistic E/E-architecture assessment is introduced. Metrics substantiating these viewpoints are linked to the model. Finally the proposed procedure is demonstrated in the context of a simplified use case.","PeriodicalId":185183,"journal":{"name":"2022 IEEE International Symposium on Systems Engineering (ISSE)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121822122","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}

Substantial investment has been made in languages and modelling tools for developing models. A key problem is that system architects and engineers work in a multidisciplinary environment in which models are not the product of any one individual. This paper provides preliminary results of a formal approach to specify models and structure preserving transformations between them that support model synchronization. This is an important area of research and practice in software engineering. However, it is limited to synchronization at the code level of systems. This paper leverages previous research of the authors to define a core fractal for interpretation of concepts into model specifications and transformation between models. This fractal is used to extend the concept of synchronization of models to the system level and is demonstrated through a practical engineering example for an advanced driver assistance system.","PeriodicalId":185183,"journal":{"name":"2022 IEEE International Symposium on Systems Engineering (ISSE)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123931985","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}
