大件垃圾资源化与减量化管理的定价决策研究

Research on the pricing decision of resource recovery and reduction management of bulky waste

针对大件垃圾的资源化与减量化处理问题,以制造商和回收商组成的绿色闭环供应链为研究对象,构建了集中和分散决策定价模型并对2种模型进行对比分析,通过理论证明和数值仿真验证模型的有效性。结果表明:随着消费者绿色偏好系数的增加,2种决策模式下的绿色闭环供应链各个最优决策变量均增加。在集中决策模式下,大件产品的绿色度、需求量、供应链总利润要优于分散决策模式下,且回收率明显高于后者,而销售价格低于分散决策模型。

Aiming at the problem of resource recovery and reduction processing of bulky waste,a centralized and decentralized decision pricing model is constructed by taking the green closed-loop supply chain composed of manufacturer and recycler as the research object,and the two models are compared and analyzed.The validity of the model is verified by theoretical proof and numerical simulation.The results show that:all the optimal decision-making variables of the supply chain increase as consumers’ green preference coefficient increases.Under the centralized decision-making model,the greenness,demand and total profit of the supply chain of large products are better than those under the decentralized decision-making model,and the recycling rate is significantly higher than the latter,while the price is lower than the latter.
