Saif Q. Models and technology of choice of technology funds in the information systems

The thesis is devoted to the solution of current scientific and practical prob-lems of developing new models and technologies of choosing of Technology Structural in the information systems. This classification by featured of information networks and the type of additional equipment reviews the information system of technical energy accounting , maximum use of existing data network company to choose the rational structure of the technical facilities which prompted predefinition of the overall structure using the methods of expert evaluation. Developed graph model considering the peculiarities interface technical facilities. Enhanced the efficiency criterion of choice of the technical facilities based on of the cost criterion. Proposed Phased method choice of the structure of the technical facilities of information systems. Based on the graph models and methods to build information technology that allows get the rational structure of the complex from a technical and technological constraints in the enterprise The proposed model and the technology choice of the structure the technical facilities of information systems implemented in industry and in universities. Keywords: design of the information system, the structure of technical facilities, the Choice of a rational structure, graph model, the cost criterion.
