Quantification of machine performance through Overall Equipment Effectiveness

Abstract

Overall Equipment Effectiveness (OEE) is a hierarchy of metrics to measure the production machine performance in manufacturing industry. OEE measurement is inspired by the Total Productive Maintenance (TPM) and used as a key machine performance tool which measures availability, performance and quality rate. This study was conducted in a manufacturing company producing a broad range of packaging products. The main issue found relating to machine productivity was where availability shows a significant decrease since the purchase date… Thus, data were collected for 12 months from the corrugator's machine and analysed using Microsoft Excel Software to determine the value of the output table, and presented graphically. The results of this study revealed that availability achieved an improvement of 5 per cent over the world standard OEE of 90 per cent, while the machine performance and quality rate each accounted for 10 per cent and 5 per cent decrease in the ‘Ideal’ value of OEE. Moreover, the comparisons with the ‘Ideal’ value of OEE were an indication level of total productivity improvement.
