ABDUL SAMAT, H.; KAMARUDDIN, S.  e  ABDUL AZID, I.. Integration of Overall Equipment Effectiveness (OEE) and reliability method for measuring machine effectiveness. S. Afr. J. Ind. Eng. [online]. 2012, vol.23, n.1, pp.92-113. ISSN 2224-7890.

Maintenance is an important process in a manufacturing system. Thus it should be onducted and measured effectively to ensure performance efficiency. A variety of studies ave been conducted on maintenance as affected by factors such as productivity, cost, mployee skills, resource utilisation, equipment, processes, and maintenance task planning jnd scheduling [1,2]. According to Coetzee [3], equipment is the most significant factor ffecting maintenance performance because it is directly influenced by maintenance ctivities. This paper proposes an equipment performance and reliability (EPR) model for measuring maintenance performance based on machine effectiveness. The model is eveloped in four phases, using Pareto analysis for machine selection, and failure mode and effect analysis (FMEA) for failure analysis processes. Machine effectiveness is measured sing the integration of overall equipment effectiveness and the reliability principle. The result is interpreted in terms of maintenance effectiveness, using five health index levels asases. The model is implemented in a semiconductor company, and the outcomes confirm he practicality of the EPR model as it helps companies to measure maintenance effectiveness.
