Filed: 1990-10-25
Abstract: PURPOSE:To improve the performance of a scheduling type expert system by finding a knowledge, which should be deleted or have the application range reduced, out of knowledges stored in a knowledge base as the knowledge contradicting the corrected scheduling result and deleting or correcting this knowledge. CONSTITUTION:A restrictive condition that a corrected job is a knowledge applied to the expression of jobs as constituting elements of knowledges and contradicts the corrected scheduling result is searched in a scheduling result 13 from a knowledge base 12 to search a knowledge as the correction object. If a pertinent knowledge is found in knowledges stored in the knowledge base 12 at the time of this knowledge search, the restrictive condition is obtained as a candidate of knowledges which should be deleted or have the application range reduced. After this candidate is presented to a user to confirm it, the knowledge is deleted from the knowledge base 12 or its application range is reduced. Thus, the performance of a scheduling type expert system 1 is improved.
