MES系統改善方案及其效益探討－以某TFT-LCD公司為例

In the market that enterprise''s management environment changes fast, the application of the information system becomes one of the important keys to improve enterprise''s competitiveness. Especially the constant requisition for immediate transparency of information in the recent years, make the manufacturing execution system (MES) play an extremely important role. MES is extensively applied in the production lines in order to improve production efficiency and get clear production information in the TFT-LCD (Thin Film Transistor-Liquid Crystal Display) industry. Using high speed technology of the computer system, it is easy to collect the information of production and monitor the factory automation and track the on-line status of work in process (WIP). This thesis uses case study way to consider the relative problems of module factory in the TFT-LCD company. According to the actual request of manufacturing, this thesis diagnoses and analyzes the production questions after using MES system in module production lines. The thesis proposes the improvement plans and compares the benefit differences of before and after improvement actions in order to shorten man-hour, save manpower, reduce produce losses and improve the production yield.
