中文摘要：
建立了由多个供应商和多个不确定需求的顾客构成的多阶段供应链动态运作模型。供应链中的供应商可以通过电子市场也可以直接将多种产品供应给不同的顾客。采用已知概率的情景集合描述顾客不确定需求，利用基于情景分析的鲁棒优化方法，建立了供应链的运作模型。该模型为一个多目标动态规划问题，满足诸如尽可能达到顾客需求、系统的总成本最小、供应商的开工率不低于某一指定水平、对应于不确定需求的决策的鲁棒性等多个相互冲突目标。数值仿真结果表明，模型的解是最保守的，但却能够有效地保证供应链运作的鲁棒性。
英文摘要：
A multistage and dynamic operation model was constructed for an electronic supply chain, which was consisted of multi--supplier and multi-customer with uncertain demands. Suppliers in this supply chain could directly provide several kinds of products to different customers or through electronic marketplace. Uncertain demands of customers were described as a scenario set with certain probability. The supply chain operation model was established by using the robust optimization method based on scenario analysis. This model was a multi-objective dynamic programming problem designed to solve several conflict objectives, such as satisfying customers＇ demands, minimizing the total cost of the system, making the availabilities of suppliers＇ capacities not below a certain level, and realizing decision robustness with uncertain demands. the most conservative whereas ensuring the robustness of Simulation result showed that solution to the model was the operation of supply chain effectively.
