Problems solved by technology

However, the situation of preventive maintenance also has a certain relationship with future investment. If only the investment in historical work is used as the basis for cost decision-making, it will lead to errors in the optimization direction of preventive maintenance, which will lead to the overall maintenance cost of the entire equipment life cycle. increase

Abstract

The invention discloses a maintenance cost evaluation method, computer equipment and a storage medium. Through the maintenance cost evaluation method provided by the invention, the overall maintenancecost of the equipment can be accurately calculated, and the calculated overall maintenance cost comprises the overall cost of historical maintenance of the equipment, the overall cost of future preventive maintenance of the equipment and the overall cost of future corrective maintenance of the equipment. The problem that the cost evaluation result is one-sided due to simple statistics generally based on historical input data is solved, the total maintenance cost of the whole life cycle of the equipment can be obtained more accurately, and a more reliable quantitative decision-making basis inthe aspect of cost is provided for maintenance optimization.

Description

technical field [0001] The invention relates to the field of equipment maintenance, more specifically, to a maintenance cost evaluation method, computer equipment and storage media. Background technique [0002] Maintenance refers to the technical activities performed to restore the function of equipment after the technical state has deteriorated or failed. It can be mainly divided into two categories: corrective maintenance. All repair work performed following a breakdown. Preventive maintenance, according to MIL-STD-721B, refers to all activities performed to maintain a specified condition by systematically inspecting, detecting and preventing incipient failures. Maintenance cost control is one of the main contents of enterprise lean management, including two aspects of comprehensive control of preventive maintenance and corrective maintenance. [0003] The current evaluation of maintenance costs is mainly based on the input statistics of historical work, including the l...
