考虑供应中断的多产品供应链鲁棒模型

考虑供应中断的情况,分析了由制造商、主供应商和备用供应商所组成的多产品供应链,采用基于区间分析的Bertsimas鲁棒优化方法来描述销售价格的不确定性,建立了供应链鲁棒模型,并进行优化求解.设计的鲁棒模型能够满足供应链三个主体———制造商、主供应商和备用供应商利润最优的目标,同时可以抵抗一定的不确定性.数值算例结果表明,当销售价格在一定范围波动时,所建立的模型具有鲁棒性.

Robust Model for Multi-product Supply Chain Considering Supply Disruption

A multi-product supply chain consisting of manufacturers, main suppliers and backup suppliers was analyzed with consideration of supply disruption. And Bertsimas' robust optimization method based on interval analysis was used to describe selling price uncertainty. Under the condition of the manufacturer's profit, the main supplier's profit and the backup supplier's profit maximization, the designed robust model could resist certain uncertainty. Numerical results showed that the proposed model is "robust" when the selling price changes within a certain range.
