Abstract

Problem Statement. Operation of industrial equipment requires its constant maintenance in good condition to keep a given level of quality and safety of operations. In order to systematize maintenance measures and reasonable expenditure of funds, equipment maintenance and repair schedules are developed. Relevance is determined by a need to organize conditions of correct operation, current maintenance, timely repair and revamping of equipment. The aim is to study methods of assessment of damages from failures and downtime of process equipment occurred due to failure to take measures on repair and maintenance and to provide an approximate economic assessment of damages and expenditures. Methods Applied. This paper considers economic factors, which should be taken into account, when developing schedules, and which have an impact on reliability of operation. The paper contains the structure and an algorithm of the calculation of losses related to the manufacturer's costs in case of an accident. The authors also made an approximate economic calculation of the costs directly related to the production equipment, including the damage caused by production downtime, the cost of operation and ownership of the equipment. Result. These calculations were given by the example of the shop for hot rolled sheets at the metallurgical enterprise. Practical Relevance. The result of the research is an assessment of losses from equipment downtime for the period and an example of the selection of the preferred equipment supplier based on an aggregate assessment of the total cost of ownership of the equipment, which contribute to evaluating financial importance of the development of competent maintenance and repair schedules.

Keywords

maintenance, repair, schedule, downtime, losses, costs, cost of ownership, reliability.
