逆向物流流量不确定闭环供应链鲁棒运作策略设计

考虑一类同时具有再分销、再制造和再利用的闭环供应链在逆向物流流量不确定环境下的运作问题.采用具有已知概率的离散情景描述逆向物流流量的不确定性,利用基于情景分析的鲁棒线性优化方法建立该闭环供应链的多目标运作模型.设计了一个数值算例,其结果验证了运作策略的鲁棒性.在该算例基础上,分析了逆向物流流量的大小对闭环供应链系统运作性能的影响.

The operation for a class of closed-loop supply chain with re-distribution,remanufacturing and reuse under the envirnment of uncertain reverse logistics flow is considered.Uncertain reverse logistics flow is described as a scenario set with certain probability.A multi-objective operating model for this closed-loop supply chain is established by using the robust linear programming method based on scenario analysis.The results of a numerical example verified the robustness of the operating strategies.Based on the numerical example,the impacts of reverse logistics flow to the operating performance for closed-loop supply chain are analyzed.
