The Wholesale Is The Leader In Supply Chain Inventory Mode, Basing On Pull Replenishment

With the development, the competition between supply chain and supply chain has already become the mainstream in market, which concentrates on the rapid reaction speed and integrated costs in supply chain, and it focuses on this indicator-the supply chain inventory. The wholesale companies were ignored because of the development of the enterprises integration, while people forget the needs of small and medium manufacturing enterprises those do not have built marketing channel for the wholesales, who also ignores the action of the wholesales about becoming the bridge, reducing transaction costs and coordinating.Therefore, for this supply chain model-"manufactures - wholesales - retails", this paper establishes a supply chain inventory control model which is leaded by the wholesales (Referred to "W-SCIM"), basing on the theory of the pull replenishment. The model take the traditional wholesales, whose competitiveness is the relatively weak, as the research object. The wholesales manage themselves’inventory directly and retails’ inventory indirectly by the way of the replenishment. So that the traditional wholesales shift to the logistics functions, truly playing its role of market regulation in the supply chain. This paper provides reference for the wholesale business adapting to environmental change and completing the transition under the new situation.To achieve the above purpose, the paper mainly studies two aspects. firstly, the paper mainly further quantitative researches the relationship between the demand fluctuations and the multiplication factor, basing on TOC, in the determined lead, and namely, the mean is negatively correlated with the multiple factor when the standard deviation is unchanged and the standard deviation is positively correlated with the multiple factor when the mean is unchanged. Finally, the paper shows a specific numerical relationship among the mean, the standard deviation and the multiplication factor, so the enterprise in the supply chain set up an appropriate amount of dynamic inventory buffer; Secondly, the paper establishes a two inventory control model. using logical thinking and mathematical model, so that the supply chain nodes enterprises are associated each other, and whose inventory is consistency dynamic managed..Finally, the paper compared with the traditional inventory managed model and the "W-SCIM" model, basing on the pull-replenishment, using the numerical simulation methods, taking the stock rate and the inventory turns as a model quality measure. The results show that the "W-SCIM" model, basing on the pull-replenishment is significantly better than the traditional inventory control, in the same order costs, about the out of stock rate and the inventory turnover.
