【正文】 庫存浪費和資金占用。這條鏈上的節(jié)點企業(yè)必須達到同步，協(xié)調(diào)運行，才有可能使鏈上的所有企業(yè)都能受益。它直接關(guān)系著供應鏈 成本 的高低和服務質(zhì)量的好壞。目前在實踐中，主要存在幾個方面的問題： 1.“鏈”上各企業(yè)仍然缺乏供應鏈管理的整體觀念 雖然我們知道供應鏈的整體績效取決于各個供應鏈上的節(jié)點的績效，但是從客觀上說，各個部門又都是各自獨立的單元，都有各自獨立的使命和經(jīng)營目標。 在供應鏈 中，各個供應鏈節(jié)點企業(yè)之間的需求預測，庫存狀態(tài)，生產(chǎn)計劃都是供應鏈管理的重要數(shù)據(jù)，這些數(shù)據(jù)分布在不同的供應鏈 組織 之間，要做到有效地快速響應用戶需求，目前許多企業(yè)的信息系統(tǒng)并沒有很好地集成起來，當供應商需要了解用戶的需求信息時，常常得到的是延遲的信息和不準確的信息。供應商管理庫存策略是指一種在用戶和供應商之間的合作性策略，其基本設(shè)想是力圖通過集成供應鏈上各節(jié)點企業(yè)的庫存控制職能，從而達到降低整體庫存費用的目的。 聯(lián)合庫存管理是解決供應鏈系統(tǒng)中由于各節(jié)點企業(yè)的相互獨立庫存運作模式導致的需求放大現(xiàn)象，提高供應鏈的同步化程度的一種有效方法。多級庫存控制的方法有兩種：一種是非中心化（分布式）策略，另一種是中心化（集中 式）策略。中心化控制是將控制中心放在核心企業(yè)上，由核心企業(yè)對供應鏈系統(tǒng)的庫存進行控制，協(xié)調(diào)上游與下游企業(yè)的庫存活動。s high inventory phenomenon. Supply chain management mode gives inventory control the following four new features: 1. The supply chain management can be exposed in the process of enterprise inventory control potential problems and crises, strengthen the inventory control degree chain management can effectively reduce the social inventory levels, reduce inventory control costs The formation of the supply chain, the requirements of various aspects of the supply chain to make optimization, establish good cooperation relationship that promote rapid product circulation, reduce social inventories, avoid inventory waste and capital to take up. 8 chain management benefit to the enterprise from the physical inventory control to inventory control change, realize the goal of informatization inventory control chain management ensures that the enterprise inventory control of flexible and rapid response capability under the environment of supply chain management, enterprise inventory are optimized, the whole supply chain the extra, dazed inventory have hit bottom, with the change of market demand, the enterprise can make a quick reaction, adjustment of product or to change strategy, effectively evade the operating risk of an enterprise. Second, under the environment of supply chain management inventory control problems Although from the macro theory, under the environment of supply chain management inventory control pared to the traditional management of inventory control have many advantages, but the whole supply chain after all is by many single enterprise form, in practice, since each enterprise on supply chain management understanding different, to own enterprise profit level concerns exist, and even some enterprise goal of independence and supply chain the overall target of abhorrent wait for a variety of causes, in actual use under the environment of supply chain management inventory control theory and method, unavoidable also can reveal many practical problems. At present in practice, there are several main aspects of the problem: 1. chain on each enterprise still lack of supply chain management of overall concept though we know of the whole supply chain performance on all nodes on the performance of the supply chain, but objectively, each department and are independent units, all have their own independent mission and business objectives. Some goals and supply chain of the overall aim is irrelevant, the more likely is the conflict. The behavior of its own free will inevitably leads to low efficiency of the whole supply chain. 2. Not accurate delivery state data when the customer orders, they want to make sure when can you deliver. Waiting for the delivery process, also may order to delivery status is changed, especially when delivery is delayed after. Many firms have not timely and accurate delivery of order of the delay modify data provided t
