In order to increase the efficiency of equipment repair work it is proposed to introduce an insurance fund that performs two functions: accumulation of payments with different frequency and cost for performing various types of repair work; payment of these works if it is necessary. The random risk process is used for the mathematical description of the insurance fund. This approach allowed us to introduce the indicators of efficiency of repair works as resource-cost risk, numerical average operating time and numerical gamma-percent resource which takes into account the fact of unrealized repair works due to lack of financial resources. A modeling program based on the event approach was created to study these indicators. Experiments based on modeling program allowed us to conclude that both risk values and reliability indicators should be preferred the variant when the frequency of payments to the insurance fund depends on the type of repair work.
