A research object is a management process by structural vitality of TCN. The aim of dissertation work is an increase of structural vitality of TCN for providing of their faultless functioning. For the decision of private tasks of dissertation the methods of approach of the systems, theory of vitality, theory of the graphs, simulation and analysis techniques, methods of analysis of operations, were used. So, for development of the system of estimation of vitality at unfavorable influence UI and system of increase of vitality of TCN the elements of approach of the systems were used. For the improvement of methods of the optimal backuping and redistribution of informative streams the elements of methods of analysis of operations were used. In the process of analysis of complex of tasks about conformity to law of maintenance the network of corresponding quality in case of damage of her elements and backer-up of this property was use the elements of theory of vitality. For the reflection of flow diagram of network, and also at the calculation of средневзвешенных sizes of maximal stream the elements of theory of the graphs were used in a network. At system of support of making decision software development in a management structural vitality was use the elements of imitation design and analysis. Scientific novelty of results : 1.Improved method of increase of structural vitality of ТCN on the basis of the structural backuping of attachments with maximal "weight" that is formed taking into account priority of streams, of way of distribution of that use these branches, provides the steady functioning of ТCN and allows to estimate probability of undefeat of functioning of arbitrary pair of knots of ТCN. 2. Improved method of increase of structural vitality of elements of ТКС by support of parameter "mediation", that, unlike existing, allows to take into account the common amount of the used ways, passing through a certain knot on the base of protocols of routing of OSPF, IGRP, EIGRP, that will assist the receipt of more exact meaning of this parameter for providing of necessary level of structural vitality of network. 3. Improved method of increase of structural vitality of ТCN by the redistribution of informative streams of requirements, that, unlike existing, allows to execute the quantitative estimation of capacity of network. 4. The quantitative estimation of vitality of ТCN, the sum of carrying capacities of routes of maintenance of requirements self-weighted on priorities of requirements corresponds the value of that (equal "1") in the conditions of the normal (without UI) functioning of ТCN, is first worked out, the change of value of that in the conditions of UI allows to define the degree of capacity of ТCN. 5. The methods of realization of the system of making decision got further development in a management by structural vitality of ТCN, the use of that gives an opportunity to manage the process of making decision with the purpose of the faultless functioning of ТCN in the conditions of UI. 6. Got further development of control system structural vitality of ТCN on the basis of application of the improved methods of estimation and increase of structural vitality. The practical value of the got results of researches consists in the following. 1. The results of calculations showed that application of the improved method of increase of structural vitality of ТCN on the basis of the optimal structural backuping of attachments provided reduction of labour intensiveness of process on to the 10%-12% comparing to the existent methods. 2. The results of calculations showed that application of the improved method of increase of structural vitality of ТCN by support of parameter "mediation" provides reduction of labour intensiveness of process on to the 8%-10% comparing to the existent methods. 3. The results of calculations showed that application of the improved method of providing of structural vitality of ТCN by the optimal redistribution of informative streams with the use of the worked out quantitative estimation of structural vitality provided the increase of capacity of network in the conditions of UI on to the 9%-12% comparing to the existent methods. 4. In the integrated environment of development of Visual C++ system of support of making decision software is worked out in a management by structural vitality, that will realize the improved methods of increase of structural vitality. 5. Authenticity of scientific results, conclusions and recommendations, expounded in dissertation work, is reasonable the correct use mathematical vehicle and by a design on ECM. The results of scientific researches found practical application in research and educational work of Educational-scientific institute of cold, criotechnologies and ecoenergy the name of V.S. Маrtynovskij to the Odesa national academy of food technologies, in project work of the State enterprise the "Ukrainian research institute of radio and television" (URIRT), that is a main branch institute that is responsible for the scientific and technical providing to industry and coordinates realization of system researches scientific research organizations and enterprises of the special State communication and priv of Ukraine, that confirmed by a corresponding act of introduction.
