Object of research - process of the control and diagnosing of functioning of management devices of digital switch systems. An object of research - models and a method of increase of reliability of devices of management of digital systems of switching with use of typical packages of diagnostic programs. The purpose of research - increase of reliability of devices of management of digital systems of switching on the basis of perfection of methods of their control and diagnosing with the help of typical packages of diagnostic programs. Research receptions - a method of the system analysis, a method of modelling, probability theory and mathematical statistics, methods of research of operations, the theory of mass service Practical value of the received results - use of the developed method of increase of reliability of devices of management of digital systems of the switching, based on use of typical packages of diagnostic programs and techniques of their choice from set existing will allow to increase readiness of devices of management of digital systems of switching up to 25 % at the certain initial parameters, and also it is essential to lower time and economic expenses for development of the software of the control and diagnosing of devices of management of digital systems of switching. The received results allow to prove requirements to reliability of the monitoring system and diagnosing, hardware and the software of devices of management of digital systems of switching and a choice of typical diagnostic programs at a stage of their designing and manufacturing. Scientific novelty of the received results - the method of increase of reliability of devices of management of digital systems of switching is developed on the basis of use of typical complete sets of diagnostic programs; analytical dependences for a rating of probability of non-failure operation of microprocessor systems to first failure are advanced; models of functioning of managing devices of digital systems of switching with two version the software with the account unequalreliability versions of the software with an opportunity of restoration system after refusal; for the first time complex models of process of the control and diagnosing of devices of management of digital systems of switching which take into account influence интенсивностей refusals, failures and restoration as hardware, and software on readiness of managing devices of digital systems of switching are received and allow to choose on these parameters typical diagnostic programs. Results of dissertational work are realized - by Ukrzaliznyza Central administrative board of automatics, telemechanics and communication in digital system of switching Meridian-1; in educational process of the Ukrainian state academy of a railway transportation; in research work, authorized the Ministry of Defence of Ukraine.
