Abstract


Overall Equipment Effectiveness (OEE) is one of the Key Performance
Indicators (KPI) for measuring the implementation of Total Productive
Maintenance (TPM) in the company. However, over time, OEE evolved
into a system for the analysis of production data with the purpose
of identifying potential areas for improvement and supporting lean
initiatives. OEE progressed from its initial role of a base measure for
efficiency to being a tool for the enhancement of effectiveness. The results
derived from OEE calculations determine the OEE element requiring
improvement. A simulation model was developed to mimic the actual
model and serve as an experimental tool. This research combines the
Taguchi method and the simulation method to acquire the data required
for measuring the characteristics of each OEE element based on multiple
level variations in order to extent the OEE as a key performance indicator
(KPI) for the company. The outcome will reveal the characteristics of each
OEE element. Through these methods, the company will be able to identify
the characteristics of the machine and decide on an appropriate production
line improvement in order to arrive at a significant result. With this OEE
extension, the company is easier to decide for priority improvement towards
better product quality, better product lead-times.
