Abstract
In Total Productive Maintenance small group activities are interwoven in each other. Overall Equipment Effectiveness (OEE) is one of the most importantpillars of TPM. OEE aims to focus areas that include machines that are operating below standards and to find out the ways for improving efficiency. OEE effectively zero down on the critical causes of downtime, whose main principle lies in maximizing the saleable outputfrom equipments by enhancing productivity in three areas- availability, performance and quality. The scope of our investigation covers over a time period of one year on the shop floor of a reputed automotive component-manufacturing unit for determining the OEEand suggesting means and waysfor improving it. Datafor past one year have been analyzed. The analysis has revealed that there are 98% good components, 2% rework losses, where the nine most common causes were identified for the machine stoppages. The OEE was 65% and the six big losses represent 35% loss of the product time. Based on the findings, it was recommended to implement a TPM to improve the OEE ofthe plant.
