Symbolic Representation of Production Knowledge in the Development of Knowledge Management Systems

Abstract

This paper presents the method of symbolic knowledge representation used for building of knowledge management system in technological production preparation of machine elements. The method is based on symbolic processing of information in the system, and the resources of knowledge were expressed through symbols. Symbolic representation of constructional forms of machine elements to load input data for designing has been elaborated. The designed structure of a technological process has been written in a symbolic way. The description of a technological operation is made according to the method of building of the symbol of an operation that allows to generate the technological process of machine element. Relations between obtained representations are described using decision rules. These rules are stored in the frame structure. With this knowledge, representation is a possible division of the decision problem for partial tasks.
