초록

대규모 플랜트에서 조업자 안전훈련 모델의 전제조건은 조업에 관련된 다양한 위험의 상세분석 및 지식표현으로 얻어진 운영절차의 범용성과 정확성이다. 본 연구에서는 조업절차의 생성을 위해 인공지능 플래닝 기법을 고려하여 조업자의 일반행위와 조치행위 그리고 기술용어 등을 분류하고, 지식의 공유 및 재사용을 고려하여 플랜트의 운영과정과 관련된 조업행위 및 용어의 확장을 지식표현 온톨로지 형태로 정의하였다. 또한 조업의 일반적인 행위의 구체화를 위해 Hierarchical Task Network (HTN)기반의 행위계획을 적용하여 목표와 실행이 가능한 수준까지 분할하여 여러 상황에 따른 절차를 생성하도록 설계하였다. 이후 실제 보일러 설비의 사례연구를 통해 조업조건과 운전상태 그리고 장치들 간의 운전목적에 따라 구성설비의 역할을 분류하고, 비상정지절차를 생성하였으며, 제안한 방법의 실제 플랜트 적용 가능성을 확인하였다. 체계적인 지식표현에 기초한 지식베이스 구축은 일반적인 플랜트 운영절차 및 조업자 안전훈련 시나리오의 생성에도 활용이 가능할 것이며, 향후 자동생성 등에도 활용될 수 있을 것으로 판단된다.

The preconditions of the usefulness of an operator safety training model in large plants are the versatility and accuracy of operational procedures, obtained by detailed analysis of the various types of risks associated with the operation, and the systematic representation of knowledge. In this study, we consider the artificial intelligence planning method for the generation of operation procedures; classify them into general actions, actions and technical terms of the operator; and take into account the sharing and reuse of knowledge, defining a knowledge expression ontology. In order to expand and extend the general operations of the operation, we apply a Hierarchical Task Network (HTN). Actual boiler plant case studies are classified according to operating conditions, states and operating objectives between the units, and general emergency shutdown procedures are created to confirm the applicability of the proposed method. These results based on systematic knowledge representation can be easily applied to general plant operation procedures and operator safety training scenarios and will be used for automatic generation of safety training scenarios.
