Information Sharing with Multiple Customer Segmentations In this paper, the benefit of information sharing is examined in a twostage supply chain with a maketostock manufacturer and two competing retailers facing a threesegment market. Each retailer has its own loyal customers and competes for the other two segments, namely stockpiling and switching. In addition, there exists a market uncertainty which can be forecasted by the two retailers. The retailers consider whether to share the forecasts with the manufacturer, who, in turn, decides whether to fully disclose the received information. In this context, three information sharing scenarios, including no information sharing, and information sharing with either nondisclosure or disclosure, are considered. By using a simulation method, the values of information sharing, the differences of manufactureru0027s total profits in these scenarios, are determined. In addition, the impacts of various factors on the magnitude of information sharing benefit are explored and the managerial implications of these results are also elaborated.

This paper aims to improve the accuracy in forecasting market demand and reduce inventory by studying the impact of information sharing strategies on inventory and revenue at all levels of the supply chain, by establishing a system dynamics model that analyzes the capability of information sharing to reduce the expected inventory of suppliers and retailers, and by examining the impact of information sharing on demand forecasting accuracy and inventory stability. Results show that the strategy of information sharing combined with setting the buffer inventory can better improve the performance of the fresh produce supply chain.
