Safety Analysis and Model Transforming in EAST-ADL

Abstract

As architecture modeling becomes the trend in automotive industry, problems are raised regarding the gaining complexity in system design and safety analysis. The current safety analysis requires large amount of manual work and the result is usually unstable. This study follows design research methodology and four artifacts are designed, implemented and evaluated. The outcomes of this research improves the current safety analysis working process by automating the model transformation and controlling version consistency between dependent model aspects. Besides, it also provides the possibility to apply safety analysis in an early stage of the development to reduce the amount of later modifications.
