급속한 도시화의 영향에 따른 수자원 및 환경문제를 보다 효율적으로 해결하기 위하여 전문가 시스템의 개발 및 적용방안을 제안하였다. 이에 따라 도시유역의 유출 및 수질에 영향을 미치는 주요 매개변수들을 선별하고 민감도 분석 등을 통해 그 거동특성을 제시하였으며, 이러한 특성들을 바탕으로 효과적 매개변수 결정법칙 등을 제안하였다. CLIPS 6.0을 적용하여 ‘사실’과‘규칙’을 기본으로 한 전문가 시스템 ESPE를 개발하였으며, 이를 안양천 유역에 적용하였

This paper intends to develop a Prototype Expert Collision Avoidance System by introducing expert system techniques into the decision block of anti-collision loop. The problem domain of this study is characterized and specified by combining the concepts of anti-collision loop and knowledge -based system for collision avoidance. Domain in knowledge which may originates from the appropriate sources such as the International Regulations for Preventing Collision at Sea 1972, Marine Traffic Laws, and many texts on the subject of anticollision navigation and good seamanship is acquired and formalized into the knowledge-base system using production rule. Finally, a Prototype Expert Collision Avoidance System is built by using the CLIPS, developed by AIS NASA written in and fully integrated with the C language, and some test-and-run results of the system are demonstrated and examined. The author considers the proposed system which is named PECAS to be meaningful as a test bed for a further refined Expert Collision Avoidance System on board the Automated Ship.
