An OEE Improvement Method Based on TOC
2018 25th International Conference on Mechatronics and Machine Vision in Practice (M2VIP)(2018)
摘要
Overall Equipment Efficiency (OEE) is applied to measure the actual production capacity of equipment, and Theory of Constraints (TOC) is adopted to improve the system production efficiency. In order to obtain the OEE improvement method based on TOC, bottleneck identification model and buffer model are established. Thus, a multi-attribute bottleneck identification model is constructed based on Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) and Entropy Method. In addition, a time buffer model based on the Drum-Buffer-Rope (DBR) theory is proposed. This OEE improvement method can significantly increase OEE of bottleneck equipment. Moreover, due to the optimization of bottlenecks, the system production efficiency is improved. The effectiveness of this method is also verified in a semiconductor package process.
