Study Of The Information Value And The Information Processing Method In Supply Chain Management Decision

With the development of Supply Chain, the conceptions of modern business management have changed. Information became one of most important resources, as well as capital. It is the time of information. Based on review of papers related with information attribute, the target of this dissertation is to make out the truth of information role in Supply Chain Management (SCM). The key point of the research is about the condition and mechanism of collaboration between the partners in SCM.In the first part, induction is used by the way of review papers about information value. After summary the information attribution in decision process in SCM. A new performance standard is constructed for information quality. Game theory is another methodology used in quantity analysis. Simulation is used to forecast the result of the competition in supply chain also. In the last parts, an example is calculated to show the methodology of information process in contract making decision.The research of this dissertation shows that information is a valuable resource in SCM. The result of the research also shows some new thing beyond former researchers. (1) Gal-Ors proofed sharing information is the best policy in Cournot Model condition. But the search of author proof that both manufacturing and supplier has the intention to keep their cost or sale price information as private information in the competitive environment of multi-level supply chains. (2) Game of information between operators and their manager, who are in a number organization in a supply chain, cause benefit lost in the whole chain when the information is sharing. (3) Price competition never helps core enterprises in different supply chains to reach Pareto dominance. Coordinate is the probably way to find solution of the problem even some facts, such as price flexibility index, manufacture's production ability, inventory quantity and inventory cost. By the method of simulation, it is proofed that the facts as price policy of the core enterprise in supply chain, variation of market constitute and production cost, are the key point to infect the competition about information game in supply chain.It is also found that competition and cooperation based on information used to be a complicated game problem, no matter to supply chain partners or competitors. Any variation in environment and competitor's policy will change the decision of competition or cooperation. A wise manager can use his foresee to build a suitable environment for other member to help each other, and win benefits together. This dissertation set up a computer simulation model to understand the mechanism of competition and cooperation in SCM.
