Examining Some Key Issues of the Maintenance Organisation from the Point of View of the Operator and the Manufacturer

Abstract

An important fundamental question of maintenance organisation after the selection of maintenance systems is the determination of maintenance cycle times. With the help of the cycle time, it is possible to determine how often the most exposed parts and lubricants have to be replaced. The replacement of components or lubricants can be expensive, but performing these activities at the appropriate time will increase the reliability of the machines. With more frequent maintenance, the number of unexpected failures can be reduced, along with the resulting costs, while maintenance costs will also increase. The paper analyses how to determine the maintenance cycle time to the minimum of both of these cost components. The rest of the analysis deals with the analysis of the strategy of the manufacturer if it is in the interest of performing maintenance and repairs done. A further objective of the study is to determine the impact of the cost increase of unexpected failure resulting from maintenance failure on the minimum of the total cost.
