Method for determining the volume of the exchange fund for aggregates for the repair of weapons and military equipment

Abstract

The introduction of an aggregate method of repairing weapons and military equipment (WME) requires solving the problem of justifying the necessary volumes of exchangeable funds (EF) of serviceable units. In most of the work, the task of determining the volumes of the EF units is being solved from the point of view of ensuring the timeliness and timeliness of the repair of weapons and military equipment. In this case, practically no attention is paid to the costs of maintaining such funds, which can lead to their redundancy.In practice, the EF units must meet two mutually exclusive requirements: to ensure the necessary operational efficiency of the WME repair and not be redundant in terms of the costs of its maintenance. In this case, it is necessary to take into account the production capabilities of the repair body for repair and military equipment, and units. In order to take into account these requirements, the solution of the problem of justifying the volumes of the EF units is solved within the so-called system of exchange funds of aggregates.The exchange fund of aggregates in the work is represented as a discrete system with continuous time and a finite set of aggregate states. In this case, the flow of failures of aggregates is assumed to be stationary Poisson.For known parameters of the failure flow of aggregates, this makes it possible to calculate their failure probability. The assumed assumptions about the Poisson flow of applications and the indicative time of their service made it possible to use the apparatus of Markov random processes to solve the formulated problem. The repair body is a multi-channel system with expectation. The approach developed and proposed in the work to determine the volumes of the exchange fund of aggregates makes it possible to calculate the probabilities of the states of the system EF.To optimize the volume of the aggregate exchange fund, the volume of annual expenses for its maintenance is used as an objective function.
