隨著產業製造環境趨向多廠生產,企業逐漸著重於多廠間的整合規劃,本研究探討多廠區製造環境的整體物料規劃問題,針對多廠訂單的分配、各廠區物料需求的展開、跨廠的物料規劃及各廠物料安全存量的設定等物料相關問題,提出一完整的多廠區整體物料規劃模式。 本研究提出之多廠區整體物料規劃模式,包括四個子模式:1. 多廠訂單分配模式:以各廠物料存貨為基礎分配訂單;2. 多廠物料需求展開模式:根據各廠區訂單產品需求,將訂單需求的物料項目與數量展開;3. 跨廠物料規劃模式:利用本研究提出跨廠規劃物料分類方法,分類適用於跨廠物料規劃模式的物料,再針對這些物料進行跨廠物料規劃,得到最佳的物料採購決策與各廠區間彼此物料支援決策;4. 跨廠安全存量設定模式:採用多廠存貨風險共擔策略下的各廠安全存量設定。 本研究發展多廠區物料規劃模式,將協助企業提升多廠區之間的物料備料與生產作業支援能力,有效地配置物料資源,降低各廠區物料存貨,增進企業因應客戶需求變動的應變能力與高度彈性,創造新競爭優勢。
This thesis presents a multi-site integrated material planning model to deal with a sequence of material planning problems for coordinated manufacturing environment. The multi-site integrated material planning model includes four sub-model as following: 1. Multi-site order assignment model: the order assignment principle is based on the material inventory at each manufacturing plant. 2. Multi-site material requirement expansion model: to evaluate the required material items and quantities according to product requirement for each manufacturing plant. 3. Coordinated material planning model: this thesis presents a material taxonomy to classify the materials agree with the coordinated material planning, and then put them into the coordinated material planning model to get the optimal material purchase policy and material transshipment support strategy in each plant. 4. Coordinated safety stock setup model: to setup the necessary material safety stock at each plant under inventory pooling strategy. This thesis develops the multi-site integrated material planning model to deploy material resources efficiently, and reducing the material inventory at each manufacturing plant. The goals help business to enhance the prepare material ability and operation support ability, which could improve business’s flexibility and competitive edge when facing customer’s demand variability.
