符合工廠物料需求之不確定為物料管理中的一項重要任務，透過物料轉運策略來降低工廠之風險為改善工廠缺料情況和減少供應鏈成本的重要方式之一。本研究之目的為探討在不同前置時間，一個共同物料倉儲中心與多家工廠之情況下，當工廠面臨缺貨狀況時，多餘物料的工廠如何以轉運的方式提供物料給缺貨工廠，以降低工廠缺貨之風險，進而維持該工廠之生產效率。本研究使用模擬方法模擬多工廠在不同前置時間下之物料轉運策略，透過有效的物料轉運配置來降低缺料工廠之風險和存貨水準。經過物料轉運策略之輔助，結果顯示在相同前置時間與不同前置時間下，策略TBAPRI可以幫助工廠有效改善缺貨情況並提升工廠面臨需求不確定之處理能力，此外，經實驗證明，如果轉運成本大於缺貨成本達到一定程度時，則不適合轉運（NLS）。

Meeting unstable demands is a crucial task for material supply chain management. Risk pooling through lateral transshipment has been proven as an effective logic to improve material supply and to reduce total system costs. The purpose of the study is to analyze transshipment strategy using simulation techniques with different lead times of material supply. A central warehouse with multiple manufactures is analyzed in the research. To eliminate imminent shortage, materials are transshipped from manufacturing plants that have sufficient supplies to the others that starve for materials. Strategies for deploying materials including priority and quantity are investigated. Three scenarios with different material lead times, demands, transportation costs, and tardiness penalties are studied. Simulation results show that TBAPRI is the most profitable transshipment strategy to improve material shortage and system costs. In addition, the research identifies that pooling risk through lateral transshipment is not advantageous when transportation cost is much higher than tardiness penalty.
