Assessment of changes in the efficiency of the system of maintenance and repair of equipment in the electric power sector of metallurgy

The problems of evaluating various strategies for maintenance and repair (MRO) of elements of fixed assets of the electric power infrastructure of an industrial enterprise in order to choose the optimal option are considered. The author suggests using three key indicators as criteria for evaluating the effectiveness of the considered maintenance strategy: the amount of costs for the implementation of the strategy, the coefficient of technical readiness of the equipment in question and the amount of maximum risk from the implementation of the strategy. Particular attention is paid in the article to the compliance of the chosen MRO strategy with the current equipment load and performance requirements. The paper considers an example of the application of the proposed methodology to real elements of the power supply of an industrial enterprise. The calculation of the listed indicators is made for a critical element of the energy infrastructure of an industrial enterprise of the metallurgical industry, the failure of which will lead to a halt in the production process of finished products.
