Abstract

The knowledge engineering approach to reliability analysis J.A.B. Geymayr, N.F.F. Ebecken COPPE/Federal University of Rio de Janeiro, Laboratory for Rio de Janeiro, RJ, Brazil ABSTRACT This paper presents the FTAES system, a knowledge based environment designed for the assessment and measurement of reliability, availability, maintainability and safety of industrial systems using fault tree representation. Object oriented structures are used to represent the problem's domain, production rules, algorithms and database structures are the basic elements of the system. FTAES was structured into an open blackboard architecture in order to allow further inclusion of real time diagnostic modules and automatic fault tree generation. Uncertainty, vagueness and fuzzyness are represented and solved with fuzzy logic approaches. 1 INTRODUCTION Procedural programming has frequently been used to implement algorithms for fault-tree evaluation. However the procedural approach surfers f
