Abstract

An expert system for fault tree analysis J.A. Bogarin Geymayr & N.F. Favilla Ebecken Laboratory for Artificial Intelligence Research f EC/COP f E, Federa/ Z7m%era% o/ ^20 de de Janeiro, Brasil ABSTRACT This paper focuses the knowledge engineering approach in the assessment and measurement of reliability; availability, maintainability and safety of industrial systems under the Fault Tree representation. An object oriented expert system application was developed with the NEXPERT OBJECT environment to perform the different stages of the analysis. Fault tree construction and simplification ,minimal cut set determination and, common cause analysis are described under such methodology. INTRODUCTION Fault Tree analysis is one of the most widely used methods for system reliability analysis. It is a formal deductive procedure for determining the various combinations of component failures and human error
