摘要
Safety architecture patterns provide knowledge about large scale design decisions for safety-critical systems. They provide good ways to avoid, detect, and handle faults in software or hardware. In this paper we revise existing architectural safety patterns and organize them to build up a pattern system. We add Goal Structuring Notation diagrams to the patterns to provide a structured overview of their architectural decisions. Based on these diagrams we analyze and present relationships between the patterns. The diagrams can also be used to argue about a systems's safety, which we show with an example.
