A Model For Selective Information Sharing

With the development of electronic technology and the Internet, it's becoming more possible to realize information sharing in the supply chain. On the basis of the situation, there have appearing many papers which are discussing about the information sharing. Most of the papers emphasize two aspects: some papers are focusing on the influence of the information sharing and calculating how much cost can be save by using information sharing, while the others stress the importance of how to complete information sharing. All the theory has produced a great deal of benefits in western countries. The development of theory has also improved the management of the supple chain, such as VMI, which is used as the inventory policy to save the suppler chain's cost.In recent years, some Chinese scholars have also made lots of achievements in the information sharing on the base of foreign research. Some of them proved that the information sharing is useful to reduce the bullwhip effect which is misuse of the information in the supply chain, and they also studied some game theory problems in the information sharing,. We should indicate the exact influence of information sharing in the supply chain in the near future. As a system, the key problem is how to use the information to improve the running of the supply chain, given that you have known the impact of information sharing.This paper studies a selective information sharing model on the basis of other researchers' thesis. The selective information sharing is a model that a supplier can only get information from only one of the retailers. The information may contain stock data, sale data or product scheme, which formed the base of the suppler chain's decision. In the model, the sharing-information retailer shares the same stock policy with the no sharing-information ones. The main purpose is to sustain the supple chain in a lowest cost. Under the research, we conclude the fact that influence the cost of the supply chain most, and further more, help the enterprise to make a decision accordingly.We use the Product Cycle theory together with the statistic data of the sale to help the suppler to dispatch goods. It is hard for us to make a decision just using the statistical data on the market, because the in most time the data is complicated. According to the analogy of statistical date of the...
