Customer demand and planning efficiency in overall equipment effectiveness (OEE)

Overall equipment effectiveness (OEE) is the multiplication of availability, performance and quality which are looking into the losses such as downtime losses, speed losses and quality losses respectively. The study is carried out in an aerospace parts manufacturing company to acquire the time data...

The study is carried out in an aerospace parts manufacturing company to acquire the time data of Autoclave section via the computerized recording system. In this study, planning factor is introduced in OEE and defined as the panel number loaded over the maximum number of panel affordable by autoclaves. This is to promote the optimization of Autoclave usage or the concept of On Time In Full (OTIF). In addition to that, customer demand is also incorporated in OEE through Takt Time. This evaluates Autoclaves with constant and fixed cycle time in varying performance ratio from time to time according to its real performance. This also provides a balance between the over-production issue and high utilization of equipment. The results of planning factor and Takt time incorporation show that curing of Autoclave was not planned up to its maximum capability; and the demand accepted is actually higher than its maximum capacity. After that, the OEE data once obtained is then used for versatile usages such as scheduling or planning of preventive maintenance frequency, examination of customer demand accepted with respect to Autoclave capacity, comparison of performance over the time horizon as well as the evaluation of material losses due to planning of equipment process. Among them the estimation ofbreakdown time (via MTBF) and priority of preventive maintenance on Autoclave is done by analyzing the availability data and the percentage of downtime composition. Another possible usage of OEE data is the calculation of material amount based on the Bill of Material (BOM) and the average of historical quality ratio data. As a conclusion, objectives are achieved since the customer demand is incorporated into OEE,efficiency of planning is examined and versatile usage of OEE value and data are demonstrated.
