Production Machine Maintenance System Design Using Reliability Centered Maintenance

Abstract

One of the indicators in increasing productivity is the level of reliability of production machines. The reliability level of a production machine is determined by the effective and efficient maintenance process of the company. A case study was conducted in a manufacturing company. In the period January until June 2019, the percentage of machine downtime is more than 3.0% (ideal benchmarking downtime for the manufacturing industry). Research carried out using Reliability Centered Maintenance (RCM). It starts with determining critical objects, then identifies each function of the assets, carries out FMEA analysis and calculates the highest risk of each failure mode, calculates proper maintenance intervals for the five highest failure modes, then ends with making a maintenance strategy by considering risk based inspection. This study aims to develop a maintenance strategy model that is better than what is currently used. By applying Reliability Centered Maintenance, machine reliability can be increased by an average increase of 39.34% and the right maintenance strategy can be found. Furthermore, it will get a new framework to become a new maintenance policy for the company.
