Research On Purchase Strategy Of "Double Pallet System" In Supply Chain

Management is to find equilibrium among the limited human resources, funds and materials. The management of supply and demand is to find equilibrium in the links of the whole supply and demand. In the equilibrium system of supply and demand logistics, supply chain is based on the competition of quality, cost and time, esp. under the circumstance that information of supply, production and sale are not corresponded with each other. The goals of supply, production and sale are conflict. Other uncertain factors: delay in logistics, uncertain demand, members of the supply chain, such as: suppliers, technology and management of the corn companies, etc. Taking all these into consideration, logistics supply and demand equilibrium is essential to promote the performance of supply chain from the point of view of supply chain. Consumers pull the reserves and plans push it. The applied force between them determines the supply and demand equilibrium. If demand is greater than plan, there are not enough reserves. Goods can't be delivered in time. If plan is greater than reserves, overstock will be resulted. Therefore, reserves are essential to keep supply and demand equilibrium and purchase strategy undoubtedly plays an important role in reserves management. To be specially, the goal of the supply chain management is to maintain equilibrium and make feasible plans that are easy to be carried out and quick in response so as to get outstanding achievements, in the process of social production, material circulation and product exchange that involves suppliers, producers, distributors and customers, in the attempt to get minimum cost, best service, minimum reserves, shortest period and the highest quality of logistics.Scholars at home and abroad have done many researches and discussions on the problems mentioned above, esp. on the functions and principles of the reserves and the influence of uncertain factors of management on purchase strategies and policies of reserves management. They have formed many mathematic frameworks (that can be used as guidance) for example, the mathematic framework that can predict safety stock when demand period is not certain or when the order is not fulfilled. All these provide a solid theoretical foundation for managers. However, in the process of management, this framework is weak in practice. Because it is hard for every managerto manage and control purchase and reserves by following strictly the framework when there is fierce competition of quality (quality of product and service, environment protection), cost, time (timely supply and service) and when many uncertain factors and time for response are considered. So in practice it is not generally used. Mathematic framework is only a prediction based on material used in the previous period, available sale information and some calculations of material needed in a certain time. So such a prediction has a tolerance. Based on these theories and the practice in a company, this thesis will focus on the problem by discussing purchase strategies of"double-plate pattern"applied in supply chain to find a pattern that is practical, acceptable, having theoretical foundation. And at the same time it is familiar to purchasers, managers of logistics and suppliers."Double-plates"system has the feature to"pull"all the information needed by the supply chain. The"pull"of the"double plates"can carry all the information needed by the supply chain. The supply chain will be in the state of having no"crack"in the"chain joints". It is just like a transmission chain whose speed can be changed freely. When the steering wheel (demand of sale) speeds up, the"double plate"on the"supply chain"will accelerate accordingly, and vice verse. In the strategic process of sale, production, supply and control of reserves, this can ensure that materials will be timely provided and material supply will follow strictly the pace of production. In this way reserves are both reduced and pushed.
