We consider a supply chain comprising a manufacturer and a platform, where the former sells its products through an offline channel and the latter. The platform has two operational modes, namely the marketplace and reselling modes. Platform power refers to the platform's ability to increase the market size, while network effects concern the platform's effect on the offline channel. Consumers may return dissatisfied products brought from the platform within a return window. Without artificial intelligence (AI), the optimal production quantities in both the marketplace and reselling modes increase (decrease) with the platform power under low (high) network effects. The optimal profit of the manufacturer in the marketplace mode increases with the platform power and the direction may be positive in the reselling mode. With AI, the optimal profits of the manufacturer in the two modes always increase with the platform power. Comparing the cases with and without AI, we find that using AI in the marketplace mode increases (decreases) the manufacturer's profit under low (high) network effects. And using AI in the reselling mode increases (decreases) the platform's profit under low (high) network effects. With and without AI, the marketplace mode cannot coordinate the supply chain, while the reselling mode can. We also extend our work by considering several cases to check the robustness of the results.

我们考虑一个由制造商和平台组成的供应链，其中前者通过线下渠道销售其产品，后者通过线下渠道销售其产品。该平台有两种运营模式，即市场模式和转售模式。平台力是指平台扩大市场规模的能力，网络效应是指平台对线下渠道的影响。消费者可以在退货窗口内退回从平台带来的不满意产品。在没有人工智能 (AI) 的情况下，在低（高）网络效应下，市场和转售模式下的最佳生产数量会随着平台力量的增加（减少）而增加（减少）。市场模式下制造商的最优利润随着平台力的增加而增加，在转售模式下可能为正方向。有了人工智能，两种模式下厂商的最优利润总是随着平台力的增加而增加。比较使用和不使用 AI 的情况，我们发现在市场模式下使用 AI 会增加（减少）制造商在低（高）网络效应下的利润。在转售模式下使用 AI 会增加（减少）平台在低（高）网络效应下的利润。无论有没有人工智能，市场模式都无法协调供应链，而转售模式可以。我们还通过考虑几个案例来扩展我们的工作，以检查结果的稳健性。在转售模式下使用 AI 会增加（减少）平台在低（高）网络效应下的利润。无论有没有人工智能，市场模式都无法协调供应链，而转售模式可以。我们还通过考虑几个案例来扩展我们的工作，以检查结果的稳健性。在转售模式下使用 AI 会增加（减少）平台在低（高）网络效应下的利润。无论有没有人工智能，市场模式都无法协调供应链，而转售模式可以。我们还通过考虑几个案例来扩展我们的工作，以检查结果的稳健性。
