Intelligent interface for data base interrogation by making use of fuzzy sets and possibility theory
The main need of the analyst working on safety assessment of high risk process plants is for reliability parameters for the components involved in the process. The existing reliability parameter sources (data collections available in the literature, component event data banks supplying statistical estimates) are fairly heterogeneous. They adopt different classifications for the same component type or use different attributes to characterize components and failure modes. In recent years attention has been dedicated to representation of information by fuzzy sets and possibility theory. This paper describes a Reliability Parameter Estimation System (RPES), the purpose of which is to supply component reliability parameters to be used in safety/reliability assessments. This system is still in the definition phase; the work reported here intends to design its basic features and capabilities.
