Optimization of preventive maintenance in production lines: an approach based on reliability statistics

Abstract

The maintenance strategy must be taken from the results required by the organization, that is, aiming to meet the budgeted costs, the defined quality and the production program. Therefore, it is up to this strategy to seek to maximize effectiveness in the relationship: use of resources, costs and useful life. This article aims to define a preventive maintenance strategy for a production line, using RCM concepts, aiming to determine an optimal periodicity for the execution of this type of maintenance activity and consequently the reduction of business costs. Experimental data were obtained from the previously referenced article, linking them to the concepts of Reliability-Centered Maintenance and the Maximum Likelihood Estimator. With this, it was possible to obtain the optimal stop times for preventive maintenance of the studied machines, assuming a ratio of costs of preventive maintenance and corrective maintenance. By following the reliability techniques covered throughout the article, a company's production line can ensure that its assets are running smoothly and that any potential issues are addressed efficiently.
