Management of Material Stocks for Preventive Maintenance of Electrical Equipment

The report presents two models for determining the optimal number of spare parts. In the first model, the task is to determine the volume of spare parts for a given period under the condition of sufficiency, i.e., absence of downtime due to lack of spare parts. The second model makes it possible to determine the optimal number of spare parts to be in stock at the start of preventive maintenance, so that the total costs during the cycle are minimal.
