摘要

TFT-LCD產業的生產環境可分為Array、Cell及模組等三階段製程，相較於其他產業更為複雜，且Cell段後段製程中又有許多製程上的限制，例如機台生產需要很長之整備時間且又有等候時間的限制，因此若能減少機台換線次數並放大加工批次，就可獲得更大之產能。
本研究目的想藉由限制理論發展而出的限制驅導式之派工法則導入現場管理，一方面評估公司最大的產能，另一方面則了解公司限制資源的產生點，協助公司將限制資源管控與異常消除，以提升限制資源至最高利用率，也使公司在製品的存貨降至最低，最終使現場排程上有最好的安排，並探討如何以產能受限機台驅導前一加工站的非產能受限機台之派工，以使限制理論生產排程發揮最大的功能。

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.
