Assessment of the resource-cost risk when organizing repair works of complex robotic equipment

Abstract

This study discusses an approach that assumes the existence of an insurance fund that performs two functions: it accumulates payments at various intervals to perform various types of repair work, and then it pays for these works as needed. A mathematical description of the organization of repair work for robotic equipment is proposed to be carried out on the basis of a random risk process that describes the state of the insurance fund. This approach allowed us to introduce the concept of resource-cost risk, which allows to quantify the effectiveness of repair work in terms of their financial support. For his research, a simulation program based on the event approach was created. Experiments using a simulation program led to the conclusion that, from the point of view of reducing the resource-cost risk, the excess of income over expenditure must be done at the expense of the initial annual value of the insurance fund. Some conclusions and statements are logically obvious, but the analysis by the method of simulation modeling allows one to substantiate them quantitatively.
