Postponement strategy is one of the effective strategies to increase the supply chain's responsiveness to productrnvariations while information sharing strategy is a type of inter-organization's coordination that the participantsrnshare useful information among them to improve the chain-wide performance. One recent finding onrnpostponement is that it can improve the demand information quality: the quality of demand forecast isrnimproved as the forecasting point moves closer to the production period and more information is gatheredrnduring the delayed period. Meanwhile, sharing demand information in supply chain has been shown to improvernthe accuracy of estimating demand parameters. Since these two types of strategies affect demand parametersrnin different ways, it is valuable to analyze the combined impact of these two strategies, called informationrnshared postponement strategy, on improving the supply chain performance. This paper studies the combinedrnimpact of place postponement and various information sharing strategies on reducing information distortionrnand provides an illustration of how these two strategies affect the demand parameters simultaneously. Thernresult shows that place postponement, combined with demand information sharing strategy, may perform betterrnon reducing information distortion than that of place postponement alone, whether it is better than information-rnsharing alone conditionally depends on lead-times before/after postponing among the participants in the chain.
