Abstract: 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.

Key words: operation management, closed-loop supply chain, operating strategy, robustness, uncertainty
