Methods of Knowledge Representation in Knowledge Management Systems for Technological Preparation of Production

The article presents a method of knowledge representation developed for the construction of a knowledge management system (KMS). The starting point of the research is to analyse the stages and decision problems in the technological preparation of production of selected machine elements. In the system there is a symbolic information processing and therefore it has been assumed that knowledge is going to be expressed with the use of symbols. The way of building the symbolic knowledge representation about the structure, based on the identification of geometric features has been characterized. The construction of the technological symbol in knowledge representation about the structure of the technological process of machine parts has been inserted. Associations between these representations in the form of decision rules, which will be stored in the system knowledge base, have been proved. A diagram of building a framework of knowledge representation and an example of record of the decision rules in the structure of the frame.
