Abstract

A knowledge based approach has been presented for the safety and reliability analysis of complex systems allowing to identify critical events and event sequences and to model the causes of these events or sequences in fault trees. It has been shown that, in addition to topological information about the system to be modelled, it is necessary also to consider process related information. The elicitation of this process related information is performed by a computer assisted qualitative analysis, making use of knowledge bases containing system/unit knowledge and an event driven reasoning process. The construction of fault trees is then performed by using generic component knowledge (in the form of rules in first order logic and frames), together with process specific knowledge (in the form of rules in zero order logic) into a goal driven reasoning process. The approach will be implemented into an intelligent software tool (STARS: Software Tool for Advanced Reliability and Safety) in which windowing, menus and graphics will be used to obtain an advanced user-interface, and in which analysis capabilities are included.
