1、論文題目一,Distribution Resource Planning (DRP) Researching分布式資源計劃研究,What is DRP,In the APICS dictionary, DRP is described as below: The function of determining the need to replenish inventory at branch warehouses. A time-phased order point approach is used where the planned orders at the branch warehous

In the case of multilevel distribution networks, this explosion process can continue down through the various levels of regional warehouses (master warehouse, factory warehouse, etc.) and become input to the mas

3、ter production schedule. Demand on the supplying sources is recognized as dependent, and standard MRP logic applies. More generally, replenishment inventory calculations, which may be based on other planning approaches such as period order quantities or replace exactly what was used, rather than bei

4、ng limited to the time-phased order point approach.,What is DRP (continued),Starting from a demand plan, DRP determines a permissible short- to medium-term plan for fulfilling the estimated sales volumes. The permissible plan determines how and when inventory should be deployed to distribution cente

It produces optimized replenishment plans based on constraints (such as transportation capacities) and business rules (such as minimum cost approach, or replenishment strategies). Finally, the replenishment orders generated by DRP will be convert

The result of DRP is optimal distribution or replenishment decisions, reduced order fulfillment times and inventory levels and improved customer service.,Why do we develop the DRP,An supply chain scenario is described

7、as follows:,論文要求,DRP研究綜述論文一篇 要求引述外文文獻 對目前國內(nèi)外DRP研究現(xiàn)狀和取得成果有系統(tǒng)地論述 提供構(gòu)建DRP系統(tǒng)模型和算法 給出該模型/算法及包含參數(shù)的理論說明,6,第三節(jié) DRP原理及應(yīng)用,一、DRP的概念 二、DRP的原理 三、DRP應(yīng)用,7,一、DRP的概念,配送需求計劃（distribution requirement planning）簡稱DRP，是一種既保證有效地滿足市場需要，又使得物流資源配置費用最少的計劃方法，是MRP原理與方法在物品配送中的運用。它是流通領(lǐng)域中的一種物流技術(shù)，是MRP在流通領(lǐng)域應(yīng)用的直接結(jié)果。它主要解決分銷物資的供應(yīng)計劃和高度問

8、題，達到保證有效地滿足市場需要又使得配置費用最省的目的。,8,二、DRP的原理,DRP主要應(yīng)用于兩類企業(yè)。一類是流通企業(yè)，如儲運公司、配送中心、物流中心、流通中心等。另一類是具有流通部門承擔分銷業(yè)務(wù)的企業(yè)。這兩類企業(yè)的共同之處是： 以滿足社會需求為自己的宗旨； 依靠一定的物流能力（儲、運、包裝、搬運能力等）來滿足社會的需求 ； 從制造企業(yè)或物資資源市場組織物資資源。,9,二、DRP的原理,圖10-1 DRP原理圖,訂貨合同,提貨單,市場預測,社會需求文件,生產(chǎn)廠資源文件,庫存文件,DRP,訂貨進度計劃,送貨計劃,10,三、DRP應(yīng)用（1）,表10-2 DRP需求與庫存處理邏輯表 物流中心B 供
