摘　　要：针对单周期需求不确定下电子零售商和供应商以期望利润最大化为目标的情况,通过数学建模来分析其在3种不同电子商务渠道模式下的最优库存,并求出需求为一般分布时电子零售商和供应商最优库存及期望利润的解析解。进一步通过仿真实验分析Drop Shipping(代发货)服务成本、需求不确定性和库存运营成本水平对电子零售商和供应商最优库存及期望利润的影响,给出电子零售商、供应商以及供应链的最优渠道选择策略。实验结果表明:纯Drop Shipping电子零售商模式在大部分情况下都最优,但对于电子零售商、供应商以及供应链整体来说,其最优渠道选择依赖于实际的运营情景。This paper focused on the e-tailer and the supplier who aimed to maximize their expected profit in a single period under demand uncertainty, analyzed their optimal inventory levels in three different e-commerce channel models through constructing mathematical model, and got the analytical solution of the optimal inventory levels and expected profits of the e-tailer when the supplier with demand was in general distribution. Furthermore, through simulation experiment, this paper evaluated the impacts of Drop Shipping cost, demand uncertainty and inventory operation cost level on the optimal inventory levels and expected profits of the e-tailer and the supplier, and showed the policy of the optimal channel choices of the e-tailer, the supplier and whole supply chain.Experiment results showed that the pure-play Drop Shipping e-tailer model was optimal in most cases, and the optimal choices of the e-tailer, the supplier and whole supply chain were dependent on their actual operating scenarios.
