Flow analysis for concurrent, reactive, real-time systems

Abstract

One of the widely used techniques in software safety analysis is fault tree analysis. The paper discusses the use of flow analysis techniques for supporting fault tree generation from software specifications. Earlier work on flow analysis techniques has focused on sequential systems. We discuss how system characteristics such as concurrency and real time reactive features impact the flow analysis techniques. The paper discusses concepts and algorithms that can be used in performing flow analysis for concurrent reactive real time systems.
