%X The article discusses the development at the design stage of mobile rope complexes of a methodology for the formation of an effective technical and economic strategy for the restoration of critical structural elements of the rope system during scheduled repairs. The technique is based on predicting the kinetics of the probability of failure of the rope system as a whole during its entire life, based on predicting the failure operation of those structural elements of the system whose failure leads to an emergency malfunction of the mobile rope complex. Modeling includes the integration of the Kolmogorov-Chapman system of differential equations, modified due to the need for a discrete change in the probability of failure-free operation of elements to be replaced at the time of scheduled repairs. As a technical and economic criterion for the effectiveness of the rope system recovery strategy, the condition for obtaining the lowest possible total cost of repairs of the rope system throughout the entire period of its operation, while ensuring the average probability of failure-free operation during the entire period of operation was adopted. The formation of this strategy includes planning the schedules, number, time points, volumes and cost of planned repair and restoration measures of the rope system. A description is given of a computer program that implements the developed technique for restoring the operability of a rope system. The results of a test example of calculation in relation to a specific designed mobile rope complex are presented.
