IC 產業的競爭核心在於創新思維與資源整合，自動化、差異化和快速回應市場改變才能降低成本、提昇競爭力；為實現上下游供應鏈智能製造策略，生產規劃與排程必須從傳統的人工作業，轉型為具有決策支援的先進規劃排程系統。
先進規劃排程系統需透過許多管理規劃技術，整體考量企業資源限制，達成供給與需求間的平衡規劃。其中啟發式演算法是近年來求解最佳化組合問題的主流，而IC產業鏈測試廠生產排程是零工式工廠排程問題，具有不同工件、不同優序、不同機台之間排序組合的特性，故擬研究應用遺傳演算法求解IC晶圓針測生產排程的最佳化組合問題，來建構先進規劃排程系統中的自動排程模組。
選擇遺傳演算法是因其具有很好的全域搜尋能力，在演算過程中，可以多點同時搜尋，跳出局部區域最佳解，以求得近似最佳解。本研究內容首先以個案公司重視的交期特性（績效指標），開發以此特性設定之適應度函數的遺傳演算法程式；再探討遺傳演算法程式中各參數如：演化代數、交配率、突變率…等對遺傳演算法之影響，並找出最佳化組合。最後蒐集實驗數據，比較自動排程模組和人工排程結果的差異，驗證以自動排程模組取代人工作業能提高排程績效。

IC industry depends on innovative thinking and resource integration. Automation, differentiation, and rapid response to market changes can reduce costs and enhance competitiveness; in order to achieve supply chain intelligent manufacturing strategies, production planning and scheduling must transform to the advanced planning and scheduling system with decision support.
The advanced planning and scheduling system requires many planning techniques to consider the overall resource constraints of the enterprise, and to achieve a balanced plan between supply and demand. In recent years, the heuristic algorithm is the mainstream of solving the optimal problem. So the genetic algorithm is proposed to solve the wafer test problem, as the job-shop scheduling problem which has different work pieces, different priorities, and different machines.
The genetic algorithm is selected because of global search ability. Multiple points can be searched at the same time, to find an approximate best solution. First, develop the genetic algorithm program of the fitness function (based on the delivery). Then discuss the effects of various parameters in the genetic algorithm program such as generations, crossover rate, mutation rate, etc. Finally, collect experimental data, compare the performance of the automatic scheduling module and manual scheduling results.
