Development of a Semi-Markov Model for Research the Functioning of the Subway Power Supply Network

This article raises the issue of the gap between the process of developing new technologies within the concepts of the Internet of Things and Smart Grids and the process of direct implementation in manufacturing and industrial enterprises. The process of implementing new information technologies lags behind the speed of their development. The process of implementing new information technologies lags behind the speed of their development. And there is also a lack of some intermediate process that would reduce this lag. At the same time, the issue of implementing new technologies is relevant for enterprises of any industry. This article considers the scientific problem of developing a method for increasing the efficiency of multiparameter subway complexes. Improving the efficiency of these systems is necessary in connection with the introduction of intelligent technologies within the framework of new concepts. This article examines the process of functioning and restoration of the “metro power supply network and its monitoring and control system” system. It is proposed to use and develop a semi-Markov model to study these processes. The development of this semiMarkov model allows us to obtain the dependencies of the probability of system recovery on the volume of diagnostic tools, on types I and II errors probability, on the time spent in the state and on the probabilities of transitions between states.
