Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Intelligent Systems’ Software Design Under Ontologies’ Control (on the Example of Integrated Expert Systems) G.V. RYBINA, A.A. SLINKOV A new approach to intelligent systems’ software design under ontologies’ control is considered on the example of the integrated expert systems’ (IES) construction, the development of which is carried out on the basis of further development of the problem-oriented methodology and intelligent software environment of the AT-TECHNOLOGY workbench by integrating the ontological approach and methods of intelligent planning and management of the development of IES with various architectural typology. Special attention is paid to the analysis of the problems of the transition from automation to the intellectualization of design processes for applied IES. The description of the basic components of the intelligent software environment model is presented with an emphasis on expanding one of the components - the technological knowledge base through the development of an applied ontology of typical IES architectures and the implementation of interaction with an intelligent planner. Keywords: integrated expert systems, problem-oriented methodology, AT-TECHNOLOGY workbench, intelligent software environment, intelligent planner, technological knowledge base, ontology model, standard design procedure, reusable components, software design.
