Leshchenko O. Improve methods of optimizing the management of infocommunication network based on the methods of catastrophe theory

Object of study: the management of information and communication network. Objective: to improve methods optimize the system control information and communication network. Methods: catastrophe theory, optimization devices and communication systems, linear algebra, calculus of functions of one and several variables, mathematical statistics, mathematical modelling, the theory of optimal control systems. Theoretical and practical results and innovation: performed a systematic analysis of networks and services infocommunications that allows to realize an optimal design of management information and communication network in case of non-linearity and non-stationary network; the features of the application and possible areas of improvement of the monitoring information and communication networks; a comparative analysis of existing research and methods to minimize the objective function, taking into account structure function gradient and Hessian matrix; is proposed for optimal network management, network elements and modes of network elements to use methods of catastrophe theory; the method of constructing the control algorithm infocommunication network under emergency conditions, using catastrophe theory; proved that small changes in the network can lead to different trajectories of the system; algorithms are optimal assessment of network elements in extraordinary circumstances. Degree of implementation: the optimization of the network in terms of operational and technical management of telecommunications networks Ukraine in SE "UNDIZ". Industry - engineering, telecommunications.
