中文摘要
      针对一条由一个主导制造商、多个上游供应商组成的供应链,为了尽可能降低制造商采购时的总成本,结合产品的价格、质量、交付三大因素, 以供应商生产能力、供应商数量折扣、供应商与制造商关系维持和制造商的库存能力等为约束条件,综合考虑制造商的采购成本、质量因素带来的销售损失和交付因素影响的库存成本,为制造商建立了多目标的多周期订单分配整数线性规划模型,通过算例对三个目标进行权重分析,通过Lingo17.0得到模型的最优解,为制造商提供一个多周期订单决策的框架。最后,对模型中几个重要的影响参数进行了灵敏度分析,并为制造商与供应商提出了一些参考建议。
英文摘要
      For a supply chain composed of one dominant manufacturer and several upstream suppliers, an integer linear programming model of multi-objective and multi-period order assignment for manufacturers was established, in order to minimize the total cost of the manufacturer when purchasing. The purchasing expenditure of manufacturers, sales loss caused by quality factors and inventory cost affected by delivery factors were considered comprehensively in the proposed model, which combined with three factors of products such as product price, quality and delivery. The proposed model took the production capacity of suppliers, quantity discount of suppliers, relationship maintenance between suppliers and manufacturers as well as inventory capacity of manufacturers as constraints. The weight analysis of the three objectives was carried out through a calculation example and the optimal solution of the proposed model was obtained by Lingo17.0, which provided a multi-period order decision-making framework for manufacturers. Finally, the sensitivity analysis of several important influence parameters in the proposed model was carried out, and some reference suggestions for manufacturers and suppliers were also put forward.
