For the factory, the most important thing is the “Production Efficiency”, the less cost with higher value. Therefore, the inefficient products will increase the cost and affect the manufacturer performance. A manufacturer should know the product performance and identify the products with poor product efficiency. It can be the basis for a factory to examine, analyze and improve the products. Meanwhile, it can also help a factory to decide if they should suspend poor efficient products, replace them with new products or adjust the product combination. The main purpose is to increase the product performance and competitiveness. This study use the “Data Envelopment Analysis”(DEA) which can handle multiple inputs and outputs, a performance evaluation methods, to do the production efficient analysis and the ranking of TFT-LCD factory’s products. To achieve efficient evaluation of the fairness and objectivity, in the index weight set using a Common Weight limits concept and the limits to join the Data Envelopment Analysis CCR model. In efficient ranking point of view, it abandons the Common Weight, a single efficient ranking method, but using “Decision Making Unit”(DMU), the cross efficiency ranking purpose, to be the ranking based method of most efficient self-evaluation. By Common Weighting and Cross Efficiency Advantages concepts, it calculated the efficient value of each DMU and sorted them by rank scoring design. That will help to identify the inefficient products produced by the TFT-LCD manufacturer. This study finally uses actual historical data of TFT-LCD manufacturer in Taiwan( referred to as A Company). It verified this study really can effectively help the TFT-LCD production plant to make the right production decision.
