Development of a preventive maintenance schedule and evaluation of overall equipment effectiveness in a selected garment factory: a case study

Abstract

Manufacturing industries around the world spend a lot of money on buying new equipment to increase production but a little is done to get hundred percent outputs from the machine. However, because of increased competency levels and demand of quality products at lower costs, buying latest equipment is not a solution unless it is fully utilized. Therefore machine maintenance and in general implementing an appropriate maintenance strategy has become increasingly important for manufacturing companies to accomplish these requirements. Preventive maintenance schedule system has become one of the effective maintenance strategies to ensure high machine reliability since it is regarded as an integral part of total productive maintenance. Performance evaluation is the most important aspects in the field of continuous improving of the production process and overall equipment effectiveness (OEE) is one of the justified performance evaluation method that is popular in the manufacturing industries to assess the machine’s effectiveness and performance. In this concern this research work has been conducted in a selected readymade garment factory to study and develop a preventive maintenance schedule system. From the comparative study of OEE analysis it has been found that downtimes are decreased and production increased in preventive maintenance schedule system. Based on the obtained result maintenance management have been suggested to maintain the preventive maintenance schedule system to maximize their productivity and minimize their overall maintenance cost.
