The Value of Information Sharing in a Two-Level Supply Chain
用分析模型量化两级供应链中零售商与上游供应商共享需求信息的价值，发现当需求随时间高度相关时，信息共享价值很大。
Many companies have embarked on initiatives that enable more demand information sharing between retailers and their upstream suppliers. While the literature on such initiatives in the business press is proliferating, it is not clear how one can quantify the benefits of these initiatives and how one can identify the drivers of the magnitudes of these benefits. Using analytical models, this paper aims at addressing these questions for a simple two-level supply chain with nonstationary end demands. Our analysis suggests that the value of demand information sharing can be quite high, especially when demands are significantly correlated over time.
