Optimization of the number of repair personnel of the enterprise using the theory of queuing

Abstract

This article addresses the optimization of maintenance personnel at a wood processing facility. The organization of equipment maintenance in one of the workshops is described, along with an analysis of statistical data on equipment breakdowns and repair work execution. The proposal involves the utilization of a closed queuing system to model the process of repair execution. Based on research results, an application has been developed to calculate key system parameters and assess the efficiency of its operation. The optimality criterion considered is a metric that accounts for the reduction in the production output due to equipment downtime and the labor costs of maintenance teams. The results of calculations determine the optimal number of maintenance personnel for the enterprise's workshop. The proposed methodology can be applied to evaluate the effectiveness of production equipment repair operations.
