Abstract
화학공장의 start-up, shutdown과 같은 비정상조업의 운전지원 시스템으로, 공정내 발생가능한 위험성을 예측할 수 있는 전문가 시스템을 개발하였다. 본 연구에서 취급하는 위험성은 공정장치의 운전전 제약조건과 운전 중 제약조건, 공정내 물질의 혼합, 접촉에 의한 위험 및 일반적으로 발생가능한 위험으로 구분하여 정리하고, 이를 이용하여 위험특성 데이터베이스를 작성하였으며, 공정의 결합구조와 상태의 표현규칙 및 공정내 위험성을 판별할 수 있는 추론기구를 개발하였다. 본 시스템을 구체적인 화학공정에 적용시킨 결과, 공정내 존재하는 다양한 위험형태를 인지할 수 있었다.
An expert system was developed to predict hazardous conditions in chemical plants as an operation-aid system for the automation of unsteady state process operation such as start-up and shutdown. In this paper, hazards in process. By using these groups, Hazardous- Conditions-Data-Base was organized, after that, the methodology to represent process topology and process states was developed. An inference engine was developed for evaluating hazards in process and applied to the practical chemical plant to identify various types of hazards.
