Methods and models of information network structure synthesis and analysis in period of life cycle

The program-technical complex of information networks is considered in the paper aiming at the creation of the system of models and methods, which makes it possible to determine the optimum composition and structure of the information network program-technical complex of various stages of life cycle. During the investigation system analysis, mathematical programming, selection theory, probability theory and mathematical statistics, imitation modelling have been used. As a result the complex of descriptive and normative models and methods for various stages of life cycle have been substantiated in frameworks of the united approach. The non-formal methods, supporting the search region expansion have been developed as well as methodology of the analytical-imitation model application. The program systems, taking it possible to make the substantiated decisions in the creation of information networks and its reconfiguration have been elaborated. The calculation of the composition and structure of program-technical complexes has been held.
