基于动态定价的多周期多目标产品回收网络设计

Design for Multi-period Multi-objective Product Recovery Networks Based on Dynamic Pricing

假定废旧品回收率为回收价格的线性函数,在废旧品供应量预测的基础上,对废旧品回收进行动态定价,且考虑回收中心的处理能力限制和库存成本,以回收网络系统利润最大化和社会效益最大化为目标,建立了多周期多目标废旧品回收网络模型。针对多目标,引入总体满意度,利用LINGO11对算例进行求解。结果表明了在各个周期废旧品供应量剧烈波动时模型的有效性和优越性。

This paper proposes a multi-period and multi-objective product recovery network model, assuming the rate of waste product recovery is a linear function of price, and dynamic pricing for recycling waste products based on the forecast of waste supply. The objective of the model is to maximize the profit of product recovery network and maximize the profit of customers, considering recycling center has processing capacity constraints and inventory cost. For multi-objective, inducing degree of overall satisfaction, and an example was solved by LINGOll, the results verify the effectiveness and superiority of the model when the supply of waste products fluctuates in each cycle.
