Methodological questions of formation of the system technical support of information-telecommunication networks

The basic concepts in relation to the object of research are described. It is shown that the formation of the system of technical support (STS) of information and telecommunication network (ITN) is an integrated system problem, acquiringpreconceptual covering of a very wide range of interrelated processes at all stages of the life cycle of ITN. Basic of them are formulated almost in the same sequence as they should be resolved in the course of creation of the STS. Consistently, the stages of research to create an STS, the tasks, and obtained results are described. The analytical model of the functioning of the STS and general scheme of the method of forming the STS are given. It is shown that the mathematical description of the processes of functioning of complex hierarchical systems, such as STS of ITN, is extremely complex and serious problem. Its solution is suggested in two stages: at the first stage, the description is given in the form of abstract mathematical formalization of the process of functioning with the use of set theory (relations on the set between sets and functional maps), and at the second stage, the most important processes in the system, such as repair, maintenance, supply of new technical means, spare parts tools and accessories are distinguished and transition from intuitive concepts to detailed mathematical description of using analytical and probabilistic models is realized. An approximate structural scheme of the STS is suggested. Basic content of the regulatory support of the STS of ITN is justified.
