A SHdy on the Development of an Expert System for Chemical Plant Diagnosis Fault -An Object Description System based on Functional Structure-
화학 플랜트의 고장원 탐색 전문가 시스템에 관한 연구 -기능구조에 의한 대상의 지식표현 방법-
Abstract
A methodology for developing an object description system based on functional-structure of chemical plant is proposed. A knowledge base for chemical plant fault diagnosis is also organized in a generic fashion using the heuristic knowledge of human operators. A plant can be seen as a hierarchical set of subsystems. Each subsystem is called a SCOPE. The state of the plant and the behavior of each subsystem is managed by the SCOPES. A computer-based system based on thls methodology and knowledge base has been developed and applied to the subprocess of ethylene plant to evaluate the effectiveness of the methodology.
