Description

<p>This paper deals with modeling and analysis of information sharing in collaboration among firms and its application. Especially, we focus on the role of information sharing in the demand forecast and the quality control of finished goods. At first, we extend the basic model of demand forecast and related information sharing scheme between a retailer and a manufacturer. The result shows that the information sharing decreases the inventory, but we see also the cost of information sharing may cancel the effect. Secondary, we consider the information sharing in the production and testing of finished goods as a selection of contract between maker and supplier, and then analyze the effect in the form of profit on both sides. Moreover, the model is extended to include the change of environment in the market, and we employ the dynamic programming to obtain the optimal solution. As a result of simulation studies, the selection of optimal contract lead the maker and supplier to better common reward level.</p>
