Fault Tree analysis of Software-Controlled Component Systems Based on Second-Order Probabilities

Förster, Marc; Trapp, Mario, in Proceedings of the 20th International Symposium on Software Reliability Engineering (ISSRE 09)

Abstract: Software is still mostly regarded as a black box in the development and its safety-related quality ensured primarily by process For systems whose lion share of service is delivered by software, process-centred methods are seen to be no longer Recent safety norms (for example, ISO 26262) thus prescribe use of safety models for both hardware and software. However, rates or probabilities for... more
