碩士 === 元智大學 === 工業工程與管理學系 === 95 === The production environment of TFT-LCD industry can be divided into three step processes: Array, Cell, and Modular. In addition, there are many process limitations during the backend manufacturing of Cell stage, which is much complicated compare to other industry. For instance, as the long readiness time is required for process workstation with the limitation of considerable lead-time of queue. Thus, it is believed that production capacity can be increased by reducing the frequency of changing product line on equipment, meanwhile, to increase the volume per working order would contribute to the same purpose. The purpose of this research is intend to eliminate the abnormal and limitation of resource control in order to improve the utilization of resource and lower the inventory of WIP and semi-finished as well by implementing the so called “Drum-Buffer-Rope” developed by the theory of constraints into production-site management. In general, it helps to assess the manufacturing capacity of an enterprise, on the other hand, it illustrates the root cause of resource limitation of a firm. In addition, the discussion will demonstrate how a resource restricted workstation drive the schedule of its previous equipment that without constraints on capacity. Thus, we may enable the best manufacturing capability and production arrangement in factory site ultimately via the theory of constraints.
