摘要

本研究針對晶圓測試廠提出ㄧ套無限產能規劃系統。本系統可分為四個模組：（1）在製品指派模組、（2）批量投料模組、（3）產能堆疊模組、（4）產能平衡模組。在製品指派模組首先收集在製品之資訊，包含測試批目前加工站別、批量數量…等。而後針對主生產排程所設定之需求，依產品之週期時間預估測試批於各加工站開工及完工時間。當在製品之數量不能滿足主生產排程所設定之需求時，便使用批量投料模組進行投料。測試批之開工及完工時間計算完成後，利用產能堆疊模組堆疊機台與治具於各日之產能。若機台與治具各日產能堆疊狀況不平衡時，可使用產能平衡模組來平衡生產資源之產能。
本研究以Visual Basic發展產能規劃軟體的雛型，並根據實際之晶圓測試廠資料加以驗証本產能規劃系統。藉由實驗設計檢驗產能規劃系統之績效，實驗的結果顯示，所發展之產能規劃系統可有效平衡機台與治具負荷不均的現象。

In this research, a capacity planning system is proposed for a wafer probe plant. Four modules are developed: WIP-Pulling Module, Lot Release Module, Workload Accumulation Module, and Workload Balance Module. WIP-Pulling Module is used to calculate the lot start time and the finish time to meet master production schedule (MPS) using WIP information such as current operation and batch size. When WIP quantity is insufficient, Lot Release Module is called. After calculating the lot start time and finish time, Workload Accumulate Module is used to accumulate the workload of machine and jig in each day. If the workload of machine and jig are unbalanced, Workload Balance Module is used to balance these manufacturing resources.
A prototype capacity planning software is developed in Microsoft Visual Basic and industrial data of a wafer probe plant are used to test the performance of the capacity planning system. Based on the design of experiments, simulation results show that the capacity planning system is effective and efficient to balance the workload of manufacturing resources including machine and jig.
