考虑消费者剩余的废旧家电回收物流网络稳健优化方法

Robust Optimization Approach for Waste Household Appliance Returned Logistics Network with Consumer Surplus Consideration

为合理设计废旧家电回收物流网络,考虑到消费者剩余对废旧家电交付行为的影响和废旧家电产生量的不确定性,建立了该类网络的稳健优化模型。利用该模型可确定收集点和回收中心的开设位置、各收集点的废旧家电收购价格、各消费者的满意收集点和不同情景下的物流量分配,通过算例验证了模型的有效性。

To get reasonable waste household appliance returned logistics network, considering the influence of consumer surplus on waste return behavior of the consumer and occurrence amount uncertainty of the waste, this paper developed a robust optimization model for this kind of network. With the help of the model, the following items could be acquired, such as robust sites for collection station and return center, waste purchase price for each collection station,favorite collection stations for each consumer, as well as logistics quantities between network nodes for each scenario. Finally, a numerical example verified the validity of the model.
