Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Conceptual Decomposition of an Intelligent Information System With Reference to Existing and Future Technological Solutions P.V. BELYAEV The article deals with the formation of the conceptual composition of an intelligent information system based on the analysis of existing architectural solutions for entry-level information systems. The component composition of the information system based on computer technologies is formulated, the main functions of the components are indicated. Based on the component composition, the file-server, clientserver and web-oriented architectures of information systems are analyzed, the functionality of the components for the listed architectural solutions is evaluated. The degree of automation of information processing when using the specified architectural solutions of information systems is analyzed. A defi nition of the concept of intelligence is given, existing and promising information technologies are indicated, and technical solutions for the implementation of similar components of an intelligent information system are proposed. The functional composition of the components of an intelligent information system is proposed, provided that it is deployed on a similar hardware. Keywords: Information system, information system architecture, information system composition, intelligence, intelligent information system, neural network, knowledge base.
