對於目前全球運籌供應鏈體系的運作環境下，企業為了提昇競爭力而擁有多廠區的生產環境已為普遍的現象；面對顧客訂單少量多樣化的需求，將使製造工廠生產的物料項目勢必會大量增加，造成各廠區物料存貨、物料前置時間、產品組合、採購成本、存貨成本、運送成本等規劃因子的複雜度，如何適當運用各廠區之資源情形以滿足訂單的需求量及訂單交期，亦即產品的生產流程是存在替代性。本研究將會投入探討多廠區物料規劃問題，尋求「每一個規劃週期內，不同廠區內需要採購及各廠區間需要互相調撥的產品數量」。 本研究主要在探討LCM 產業於多廠區製造環境下的物料規劃問題，以存貨滿足在多廠製造環境之需求的前提下；規劃多廠的物料規劃及各廠物料相關問題。考慮企業整體的作業成本與各廠的物料庫存數量，在滿足訂單交期與物料採購限制下，使該規劃區間內承接訂單的利潤總和最大，並且提升廠區間資源共用程度。由於企業可能面臨不同的規劃情節，因此將以訂數量多寡、企業規模大小及不同的調撥策略進行測試，結果證明訂單數量多寡在規劃運算上有相當大的影響，而企業採用全域調撥策略將帶來更大的利潤。 The issues of Supply Chain Management of global logistical environment, so many enterprises own multi-site production situation in order to promote itself with an advantageous position. To face the customer requirement is many models and less quantity will be bound to increase the item of manufacturing product and to make planning be more complex of the material inventory at each manufacturing plant, the lead time of purchasing material, product mix, the purchasing cost, the holding cost, and the transporting cost. How to use the resources of each manufacturing plant appropriate for the satisfying production planning, that is to say the production flow that is the existence of substitute situation. The research interests in the material planning of the multi-site to find a good coordination mechanism that is the number of purchasing material and the number of transporting material between different manufacturing factories in per period.The research main presents development of a material planning for liquid crystal module manufacturing in multi-site environment and plans the material issue of the multi-site that uses the stock to satisfy the demand. Consider enterprise's whole framework operation cost and quantity of supplies stock of different factory, under handing in one and purchasing limiting with supplies to delivery date promise to customers, make the profit total that should plan to accept the order in the block largest, and improve interval resources of factory and share the degree.Because enterprises could meet various production environments, it indicates that through the number of orders, the scale of enterprises and the different allocation tactic to test the material planning approaches. The results prove that the number of orders is very influential factor and enterprises adopt the universe allotting will bring more profit.
