Effect of Preventive Maintenance on the Production Line Machines and Systems Reliability: Case Study

Abstract

The aims of this study are to introduce the appropriate preventive maintenance to the production line machines at the company to increase their reliability and reduction the shutdown, and to obtain more safety. Mean time between failure, mean down time and availability are investigated as the best indicators to generally evaluate all type of maintenance. Pareto diagram and Effect-Cause techniques both have been used for identifying where and what are the problems in the production lines. The big and serious way that the company staff was using was maintenance of run to failure. Many solutions in this paper are introduced to the company to follow the proper preventive maintenance. After one year monitoring to those production lines, their productivity increases by 15.47% and the reliability becomes high.
