Purpose of the study. The aim of the research is to substantiate the analytical provisions of engineering management of the state of independent elements of plant engineering. The practical result will be the formation of the initial provisions of Smart-technology of engineering management to change the state of independent elements of plant engineering. Research methods. The methodological basis of the work is the generalization and analysis of known scientific results regarding the engineering management of the state of independent elements of plant engineering, and the use of a systems approach. Analytical method and comparative analysis was used to form a scientific problem, determine the purpose and set research objectives. The main provisions of the theory of systems engineering, methodology of systems analysis, theory of matrices, differential calculations and research on the theory of graphs, the theory of Markov processes, Bernoulli's theorem was used to create analytical models. The results of the study. The article considers the solutions that allowed substantiate the differential equations that characterize changes in the state of agricultural machinery in the complex of plant engineering, similar to which in the theory of Markov processes is called equations of reproduction and death. The analytical paper uses the ergodic property of Markov processes, according to which the existence of a limit or established regime of stationary probabilistic process of changing the state of agricultural machinery in the complex of plant engineering systems is established. The article considers the probability models of changes in the state of agricultural machinery in the aggregate of plant engineering systems, which tend to the limit values and do not depend on the initial distribution of . The solution of these models for the regime, we can find the probabilities of , where , of all possible states of agricultural machinery in the aggregate of plant engineering. This was used to determine the level of technical readiness of agricultural machinery. According to Bernoulli's theorem, it is established that with increasing number of experiments, namely state transitions in the analyzed case, the frequency of the event converges in probability with the probability of the event, and for the regime. Conclusions. As a result of research: - new scientifically sound technical and technological solutions and developments were obtained, which are aimed at substantiating the analytical provisions of engineering management of independent elements of plant engineering, which will serve as the starting point of Smart technology of engineering management. - it was confirmed that the intensity of recovery, in addition to the number of faulty agricultural machinery in the structure of crop production technologies, also depends on the nature of faults and the type of troubleshooting, and the type of engineering management tools. - the analytical provisions for determining the relationship between the coefficient of technical readiness of agricultural machinery, the reliability of agricultural machinery and the power of engineering management in the structure of crop production technologies are substantiated. Key words: restoration, coefficient of technical readiness, agricultural machine, reliability, system engineering.
