Abstract

The growing interest in life extension for power plant components and the need to enhance accuracy and reliability of damage assessment encourage the use of innovative computer techniques such as artificial intelligence and expert system technology. The problem of estimation and management of residual lifetime of steam headers is approached from a knowledge engineering viewpoint. The suitability of artificial intelligence to deal with the domain problem and the adopted methodology are shown with reference to the prototype of ARTIC expert system. The paper describes how the complexity of the domain problem can be handled successfully by the tools which the proposed technology makes available. Lastly, the architecture of the expert system and the features of the problem solving methodology are presented, as they result from the knowledge engineering approach to the problem. The difficulties of the elicitation stage are pointed out.
