Research On The Optimization Of Multisupplier-Single Manufacturer-Multiretailer Supply Chain

With the changes of market environment, the uncertainty and individuality of the user's needs increasing, product life cycle becoming more and more shortened, product structure becoming more and more complicated, market demand becoming more and more difficult with assurance, The management mode of supply chain arise at the historic moment. In the environment of supply chain management, the optimization of inventory plays a critical role in reducing supply chain cost, improving the competitiveness of supply chain. Seeing that the researches of supply chain at present concentrate mainly on some parts of supply chain, while, seldom study it as a whole, from the systematic, dynamic characteristics of supply chain, the paper, from the characteristics of supply chain system, constructs the systematic model frame of the joint inventory based on two-stage supply chain management in systematic views. First of all, the paper optimizes the borders of supply chain inventory system. a set of index sign system of synthesized evaluation for cooperative partner is established, analytical hierarch process and fuzzy evaluation are assembled as the method of evaluating cooperative partner on supply chain ,the borders of the inventory of the post and telecommunication apparatus company's have been optimized with the index sign system of synthesized evaluation and the method for cooperative partner established above. Consequently, The supply chain inventory is a complicated system, however the system dynamics honored as the policy lab is the solution of this kind of problems. Consequently, the paper constructs the system dynamics model of joint inventory based on two-stage supply chain with the thinking of supply chain management and the method of system dynamics. It is indicated that the model is rational, effectual through the test of the model. Then, thinking of the current situation of the inventory of the post and telecommunication apparatus Company's, some meaningful conclusions have been drawn through the simulation and the optimized analysis of the model established above: the optimization of the structure elements of inventory is the prerequisite of the optimization of inventory system, is also the key for joint inventory model to be realized. It is indicated that the joint inventory mode is far superior to the traditional inventory mode; the Expected volume of inventory is the main variable that is often used controlling inventory system. Finally, the paper proposes one's own imagination further to the paper.
