Errors may occur in the information received by a manufacturer from the retailer. There are two types of information errors: transmission error that occurs in the transmission of information from the retailer to the manufacturer, and source error that occurs in the data observed by the retailer. This paper studies the value of information sharing in the presence of either or both types of information errors. In particular, when information is shared, the manufacturer may use both the shared demand information and the retailer's order quantity to make decisions, or it may rely solely on the shared demand information and disregard the retailer's order quantity when forecasting demand for the future. We analyze the values of information sharing for both settings, and characterize the lowest forecast error information sharing strategy for the manufacturer. Our results suggest that transmission error and source error have significantly different impacts on the value of information sharing and the manufacturer's optimal strategy.

制造商从零售商处收到的信息可能会出现错误。有两种类型的信息中的错误的：传输错误发生在的信息从零售商制造商的传输，以及源误差这发生在零售商观察到的数据中。本文研究了在存在一种或两种类型的信息错误时信息共享的价值。特别是，当信息共享时，制造商可能会同时使用共享的需求信息和零售商的订单数量来做出决策，或者在预测未来需求时可能仅依赖共享的需求信息而忽略零售商的订单数量。我们分析了两种设置的信息共享值，并描述了制造商的最低预测误差信息共享策略。我们的结果表明，传输错误和源错误对信息共享的价值和制造商的最优策略有显着不同的影响。
