摘要

本研究針對驅動IC晶圓測試廠，提出一個產能規劃之排程系統。針對客戶急件出貨需求，依照拉式生產之模式，依產品的測試時間進行預估貨批於各站點的起測時間與產出時間。當預計產出時間無法滿足出貨需求時，便以執行修正模型，使其初始的預估產出作為生產目標。並將此修訂後的模型所計算出貨批的生產等級，匯入排程系統內執行生產安排。另外每天分為兩次執行修訂模型運作，工廠可依據客戶需求修正後的客戶產出需求日，以及產線實際運作的生產狀況，進行系統模擬，然後將模擬出的延遲貨批給予新的生產等級。使其滿足客戶之急件出貨需求。
本研究以Visual Basic開發之新排程模型，主要分為兩個部分，第一是建立驅動IC晶圓測試的排程模擬模型，並依據案例公司實際的測試資料，加以驗證本研究新排程概念模型系統。第二是提出新的急件生產等級修正模型，配合新排程概念模型系統，來提升急件產品之出貨達成率。
經由實際的資料驗證，以及前後效益分析比較，加以驗證新的排程模型系統對急件出貨的達成率，能夠確實有效的由原本出貨達成率由81.4%提升至84.0%。實驗的結果得知，本研究所發展之產能規劃模擬系統，可有效提供生產排程管理的改善方法。

This study provides driver IC wafer testing factory a scheduling system for capacity planning. The pull production is used to meet the customer's urgent shipment demand, and the start time and output time of each station are estimated according to the test time of products. When the estimated output time cannot meet the shipping demand, the "adjusted model" is executed, so that the initial estimated output is used as the monthly production target. The adjusted model calculates the production grade of the lots and imports it into the scheduling system to arrange the production sequence. In addition, the adjusted model is executed twice a day. The factory can perform a system simulation based on the revised customer output demand date and the actual producing status of the production line, and then rearrange a new production grade for the delayed lots. Make it meet the customer's urgent shipment.
Visual Basic is used on this study to develop a new scheduling model, and it is divided into two parts. First, establish a scheduling simulation model for driver IC wafer testing, and verify the new scheduling concept of this study based on the actual test data of the case company. Second, this research proposes a new urgent production grade adjusted model, and it combines with the new schedule concept model system, to improve the OTD of the urgent lots.
After the actual data verification and benefit analysis, the new scheduling model system can increased the OTD of urgent lots efficiently from 81.4% to 84.0%. The results of the experiment show that “the scheduling system of capacity planning” providing an improvement method for production schedule management.
