Abstract

화학공장의 운전절차 자동 합성은 공장 안전을 향상시킬 뿐 아니라 설계 비용을 줄여 주지만 기존 방법들은 조작에 의한 공정상태의 변화를 모사하는 방법, 운전목표 달성에 필요한 조작과 중간목표의 선택 방법에 많은 한계를 가지고 있다. 따라서 본 연구에서는 목표사이의 복잡한 상호작용으로 인한 조작선택의 어려움을 해결하고 공정지식을 보다 효과적으로 표현하기 위해 필요한 제약조건 전파 기반의 통합 프레임워크를 제안하였다. 제안된 방법론은 중간목표사이의 상호작용이 매우 심한 공정에 적용하여 그 유효성을 입증하였다.

The automatic synthesis of operating procedures for chemical plants improves plant safety and reduces design costs. However, the existing operating procedure synthesis techniques have limitations in simulating a change of process states by the operation and selecting operations and subgoals needed to achieve the operational goal. So in this study, we have proposed the integrated framework based on constraint propagation to resolve problems about operation selection due to subgoal interaction among subgoals and to effectively use the process knowledge. The proposed methodology has been successfully applied to the process with serious subgoal interaction.
