Analysis of performance and the Overall Equipment Effectiveness (OEE) in a manufacturing company

Abstract

The Overall Equipment Effectiveness (OEE) has become an index of efficiency in terms of the use of machinery, equipment and production resources. It allows entrepreneurs to learn where to look for modest losses, and can be used to eliminate them. The main purpose of determining the OEE is to confront the theoretical use of machinery with the actual one, using a relationship of three main elements: availability, use and quality. The purpose of the paper is to present the experience of the use of the OEE in optimization of production processes in a production company. The most important factor in analyzing the overall effectiveness index of the equipment is choosing the right method for collecting and processing data. The best-known method is filling in of a worksheet by line employees. An analysis was carried out in a production company, determining the SLE production line performance index and using Pareto analysis results, based on data from May 2014 to June 2015. The bestperforming component of the OEE is quality, the value of which has not dropped below 95% over the period considered.
