Background. The existing organization of the planning and management of TC RTS has a number of disadvantages: the diversity and the stochastic nature of the impact of operational factors on the RTS lead to the fact that at the same time or the duration of the operation objects have different actual state, in this connection, the operating time or calendar life does not characterize uniquely the TS of the object during operation; maintenance in the operation of RTS is carried out with the obligatory combination of the time and place of the established types of THE same name and frequency, all the composite parts of the equipment without taking into account their operational and technical characteristics; low maintainability of equipment, leading to significant costs for the period of exploitation; the need to maintain the indicators of combat readiness of the RTS at a given level in terms of reducing material, time and labour costs.
. Main goal: to develop a mixed system of control of technical condition (TC) radio equipment (RTS), the distinctive feature of which is a comprehensive approach to solving the problem of technical maintenance (THAT) of the RTS to determine the scope of preventive maintenance (OL) through the application of selected methods of management of the vehicle and algorithms to predict the frequency and scope of PR in which the expense is minimal and the probability of  failure is not lower than required.
Methods of solution
. Mathematical calculations are carried out using methods of probability theory and mathematical statistics, methods of integral and differential calculus, the analytic hierarchy process, method of group account of arguments, singular spectrum analysis, principle of optimality of Bellman.
Results. It justifies the approach based on representation of the studied SP Z(t) in the form of canonical decomposition V. S. Pugachev. To obtain an analytical description of the investigated SP and reproduction of many of his implementations were carried out experimental investigations to assess and predict TC RTS. Based on the results of the research developed a comprehensive methodology THE RSBN-4N. The experiment measured the prediction parameters of the RTS, members of the RSBN-4N, when performing monthly maintenance, IT-1, with the purpose of obtaining estimations of probability characteristics and prediction of TC products. The analysis of the measurement results of the prediction parameters during TM-1 and check on the backgrounds of their normal law of distribution of random variables. So, when the degrees of freedom r=2 hypothesis can not be accepted – ( ; χ2=176,99). With this in mind, the second stage involved additional data on measurements carried out in conducting monthly maintenance. The re-inspection was performed using the χ2 criterion and by evaluation of skewness and kurtosis based on the results of the 10 products included in the RSBN-4N with different operating time. The test results confirmed the hypothesis of normality of the distribution of measurement results. To solve the problem of predicting the TC of the product in the third stage of the algorithm, allowing to consider values of a particular implementation and to obtain on this basis the implementation of the a posteriori SP.
. Developed a mixed system of the technical state of RTS, the distinctive feature of which is a comprehensive approach to solving the problem of maintenance of RTS that allows for point-in-time multiple of the period, to define the scope of PR through the application of selected methods of management of the vehicle and algorithms to predict the frequency and scope of PR in which the expense is mi nimal and the probability of failure is not lower than required. The basis of constructing methods are the relationship between management models of the technical state of RTS, the modernized method of forming a mixed system of management of the vehicle based on the decomposition of RTS, algorithms to predict the frequency and scope of PR, test, and evaluate.
