동력전달용 치차설계 전문가 시스템 개발연구(I) -치차파손의 원인과 대책의 진단-
Development of Expert System For Designing Power Transmission Gears(I) -Diagnosis of the Causes and Remedies of Gear Failures-
초록
본 연구에서는 동력전달용 치차설계 전문가 시스템을 구축하기 위한 일단의 연구로서 먼저, 치차의 시험중 또는 사용중에 일어나는 파손에 대하여 파손의 원인탐 색과 대책수립을 위한 전문가 시스템을 개발한다.
An expert system is developed which can diagnose the causes and remedies of the failures of power transmission gears. The basic components of the expert system are knowledge base, inference engine, and working memory. The knowledges in knowledge base are classified into the knowledges for determining the failure types and for diagnosis of causes and remedies of the failures. The former is represented hierarchically into the main category of eleven groups by rules and the sub category of twenty four groups by facts, while the later is represented by facts according to the each group of knowledges. In the inference engine some considerations are implemented, i.e., the backward chaining method and depth first search to determine the category of the failures, the meta-knowledges to shorten the search space, the certainty factor to evaluate the reliability of result, and the unification strategy to diagnose the causes and remedies of the failures. The working memory is established to hold the results during inference temporarily. In addition, knowledge acquisition facility, explanation facility, and user interface are included for the usefulness of user. This expert system is written with the PROLOG programming language on IBM-PC compatible computer operated by MS-DOS and be executed alone.
