Towards an Integration of Standard Component-Based Safety Evaluation Techniques with SaveCCM

摘要

To deliver complex functionalities in a cost effective manner, embedded software should ideally be developed with standardized interoperable components. At the same time, most of these embedded systems must be demonstra-bly safe and reliable. This paper aims to extend SaveCCM, a modelling language for component-based embedded systems, with standard safety evaluation models. Based on this extension, failure and hazard probabilities can be estimated early in the development process and can be used to check if a system can fulfil its safety requirements. The procedure of the safety evaluation is demonstrated with the case study of a computer assisted braking system.
