in the article the method of finding the optimal value of the probability of failure-free operation of machine parts with constraints on resources, the characteristics of the structure and economic performance. The algorithm for calculating the total economic cost of failure removal, implemented in the software algorithm block MRM and choosing the best option of manufacturing parts. As an example, the handle of the EC-14, single-bucket excavator. The optimal uptime probability value equal to 0.999 and corresponds to the structure, which is 7% more than the original, but is reduced to 2.2 times the total cost of eliminating failures.
