需求不确定环境下闭环供应链的鲁棒运作策略设计

建立了顾客需求不确定环境下一类同时具有再分销、再制造和再利用的闭环供应链动态运作的鲁棒优化模型。该闭环供应链由一个制造商和一个供应商构成,废旧产品的回收及对废旧产品的再处理均由制造商完成。闭环供应链的运作是动态的且满足诸如供应链成员之间协调、各成员运作收益最大等多个目标。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。设计了一个数值算例,其结果验证了运作策略的解鲁棒性和模型鲁棒型。

Robust Operating Strategy Design for a Closed-Loop Supply Chain under Circumstances of Uncertain Demands

Under the syntheticall consideration of re-distribution,remanufacturing and reuse,the dynamic operating model for a closed-loop supply chain is established. The closed-loop supply chain is composed of one manufacturer and one supplier,in which the manufacturer is in charge of recollecting and re-disposing the used products. The operaton of closed-loop supply chain is dynamic and meets multi-objectives such as coordination between members,maximum profits of each member. 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. A numerical example is designed,its result verified the solution robustness and model robustness of the operating strategy.
