Abstract
Purpose. Development of the mathematical model of operation of the four-unit station exit signal as a Moor finite discrete automaton. Methodology. The development of the mathematical model of the light signal with four light units as a finite discrete automaton requires the construc-tion of the automaton state graph, to encode the inputs, outputs and transitions of the automaton, to construct sequential equations and to minimize them. Also on the trigger basis, it is necessary to create a memory cell to store the previous state of the automaton. Results. The resulting math-ematical model of the light signal can be used for the testing of the correctness of operation of the MPC systems, which will allow avoiding the occurrence of some dangerous situations during their operation. Scientific novelty. During the work, the mathematical model of operation of the exit light signal with the train and shunting signals as a Moore finite discrete automaton was cre-ated. The practical significance. Due to the obtained model of the light signal, it becomes possi-ble to simulate the operation of signals using computer technology by combining the occurrence of various types of failures at different moments during the train station movements and creating both train and shunting routes. This allows tracking the reaction of the system and the object on failures at the stage of testing and running.
