设计了一类由一个制造商和一个供应商构成的同时具有再分销、再制造和再利用的闭环供应链,废旧产品的回收及再处理均由制造商完成。建立了该供应链在顾客需求不确定环境下的多目标鲁棒动态运作模型。采用具有已知概率的离散情景描述顾客需求的不确定性,利用基于情景分析的鲁棒线性优化方法建立供应链的运作模型。设计的数值算例的结果验证了运作策略的鲁棒性。
A class of closed-loop supply chain with one manufacturer and one supplier is designed, in which re-distribution, remanufacturing and reuse are considered synthetically. The manufacturer is in charge of recollecting and re-disposal the used products. A multi-objective robust dynamic operating model for the supply chain under the circumstance of uncertain customers ; demands is established. Uncertain demands are described as a scenario set with certain probability, the supply chain operating model is constructed by using the robust linear programming method based on scenario analysis. Results of a numerical example verify the robustness of the operating strategy.
