Dynamic reliability: towards an integrated platform for probabilistic risk assessment

Abstract

Abstract Dynamic reliability methods are powerful mathematical frameworks capable of handling interactions among components and process variables explicitly. In principle, they constitute a more realistic modeling of systems for the purposes of reliability, risk and safety analysis. Although there is a growing recognition in the risk community of the potentially greater correctness of these methods, no serious effort has been undertaken to utilize them in industrial applications. User-friendly tools would help foster usage of dynamic reliability methods in the industry. This paper defines the key components of such a platform and for each component, provides a detailed review of techniques available for their implementation. This paper attempts to provide milestones in the creation of a high level design of such tools. To achieve this purpose, a modular approach is used. For each part, various existing techniques are discussed with respect to their potential achievements. Issues related to expected future developments are also considered.
