Abstract

Recent growth in the area of model-based productdevelopment in the automotive industry means that systemmodels in electronic form become increasingly moreavailable as they progressively find more applications inthe course of the development process.Such models,Matlab-Simulink models for example, are currently usedfor simulation, fault injection and source codegeneration.In our work, the utility of such models ispushed further into a hitherto unexplored area that ofsafety and reliability analysis.We propose a design process in which techniques forsemi-automatic safety and reliability analysis of suchmodels are combined with multi-criteria optimisationtechniques to assist the gradual development of designsthat can meet set reliability and safety targets withinpragmatic cost constraints.The proposed process relieson tools to automate some aspects of the design that webelieve could be automated and thus simplified withoutany loss of the creative input brought in the process bydesigners.
