Abstract: A qualitative solution to the problems of estimated assessment and further design, control, diagnostics and operation of a technical system, using the example of vehicles, contributes to the formation of professional competence among graduates of a polytechnic university in the specialty 23.05.0 «Land transport and technological means» and the training area 23.03.03 «Automobiles and automotive industry», within the framework of studying special chapters of mathematics. The study of vehicle reliability issues, during the implementation of the educational process, is determined by improving the quality of training specialists in the automotive industry and, as a result, improving the quality and safety of road traffic. The author substantiates the importance of introducing mathematical models based on Markov processes in the course of monitoring and diagnostics of technical systems to predict the reliability criteria of a technical system: the probability of failure-free operation; failure rate and recovery; downtime and continuous operation; average operating time before the first failure; stationary values of the system availability coefficient, etc. The issues of reliability of technical systems were considered by the author in unity with mathematical tools; the formulation and solution of problems was carried out on the basis of graph theory, matrix calculus methods for solving systems of linear algebraic equations, basic theorems of probability theory and mathematical statistics. An algorithm for the implementation of interdisciplinary educational tasks for the control and diagnosis of a technical system is presented; models of technical tasks for the operation and maintenance of vehicles implemented on the basis of Markov processes are listed; a list of specific tasks for a step-by-step study of a technical system is compiled; an example of the compilation and subsequent solution of a system of linear algebraic equations for the case of a stationary value of the probability of states is analyzed.
