中文摘要：

研究了两阶段销售期末存在未售完产品进行回购的服装供应链订货模型。由于策略型消费者的存在,零售商在第一销售阶段原价销售,第二销售阶段降价销售,基于两阶段消费者的不同购买比例建立了关于策略型消费者的服装供应链订货问题的分散决策模型和集中决策模型,分析了两阶段销售及不同回购价格对订货量的影响。通过数值算例发现从零售商、供应商及供应链角度出发的订货量及对应的利润变化关系,认为随着放弃购买比例的增加,最优订货量出现先增加再减少的过程,而利润会逐渐降低;随着回购价格的提高,最优订货量减少,供应商的利润减少,零售商的利润却增加。

英文摘要：

The apparel supply chain ordering model for unsold products in the final stage of two-period sales was studied in this paper. Due to the existence of strategic consumers, retailers sold at the original price in the first phase of sales and sold at the promotion price in the second stage of sales. Based on the different purchase ratio of consumers in the two stages, decentralized decision-making model and centralized decision-making model of apparel supply chain ordering problem related to strategic consumers was established, and the influence of two-stage sales and different repurchase prices on the order quantity was analyzed. The relationship between the order quantity and corresponding profits was found from the perspective of retailers, suppliers and supply chain through numerical example. A conclusion was drawn that as the ratio of abandoning the purchase increased, the optimal order quantity first increased and then decreased and the profits also declined gradually; as the repurchase price rose, the optimal order quantity reduced and the profit of suppliers reduced, while the profit of retailers increased.
