Object-Oriented Representation of Mixed Models Knowledge in the Design of Electronic Devices in CAD Electra

摘要

At present days a promising direction is the development of information management systems design, allowing to describe the subject area in the form of a set objects. The purpose of this paper is to consider representation models knowledge in expert systems and highlighting the benefits of using object-based -approximate representation of knowledge about the design area radio device. This paper outlines the principles of construction object-oriented knowledge base management systems that would be compatible with existing programming languages with respect to structures representations of managed knowledge and would provide opportunities to integrate them into expert systems operating on the basis of the concept of open systems. It is proved that the most optimal is the separation of knowledge and meta-knowledge complex mixed types resulting from inheritance. At the same time, internal representation of complex objects formed as a result of inheritance, looks like inheritance chains. When working with complex this system automatically searches special links, allowing you to perform operations according to the SQL standard.
