摘要
针对考虑顾客有限"碳行为"偏好的选址-路径-库存联合优化问题,引入环保度系数作为碳排放量的特征向量,在低碳产品加价率存在的情况下,刻画了顾客有限"碳行为"偏好和市场逆需求系数对低碳产品需求量的影响,构建了选址-路径-库存系统中考虑有"碳行为"偏好的联合优化模型,并分析了顾客行为偏好对企业收益的影响。使用基于NNC的多目标求解方法,对考虑成本和碳排放的双目标问题进行处理并得到一组Pareto解集,数值实验证明了产品环保度、顾客有限"碳行为"偏好对企业运作方案和收益水平的影响。
The optimization of supply chain network considering both cost and emissions is a hot topic now.However,the traditional researches mostly focus on the trade-off among economic cost,customer service and others.In this paper,a supply chain network model considering the cost and emissions of location,routing and inventory is designed.Also,the consumer environmental behaviors（CEBs）are incorporated.CEBs not only affect consumers＇ willingness to pay premium prices for low carbon emission products,but also the overall demand for low carbon emission products.Specifically,it＇s assumed that the price premium for eco-friendly product is px=pθ2x.Where pis the price of the normal product,pxis the price of the ecofriendly products,andθxis the green level coefficient of products.The demand function describes as dx=d＋τθx-λpx.Where dxis the demand of the eco-friendly products,dis the initial demand without considering CEBs or a premium for greener products,τis the consumers＇ environmental preference for low carbon products,λis the market inverse demand coefficient.The contributions of this research can be listed as follows.First,a multi-objective model is constructed,which provides a trade-off between costs and carbon emissions.The NNC method is used to solve the model,and then a Pareto optimal set can be obtained.After that,the revenue function based on the Pareto solutions is proposed.In the computational experiments,the model is tested by the data from the Northeast Chemical Sales Company of CNPC.The obtained Pareto optimal curve provides a portfolio of configurations for decision makers.Then,the same technique can be used to obtain the revenue curves from different carbon emissions.Hence,the unique optimal revenue levels and the relevant decisions can be acquired.Finally,the sensitivity of the case study was analyzed.We are interested in the effects of CEBs on the demand and revenue in a three-level supply chain.The results show that more positive CEBs result in greater demand and higher revenue.Also,it＇s observed that the pricing of low carbon operations is critical.Therefore,enterprises should make marketing efforts to strengthen consumers＇ environmental preferences.Companies should support their claims to consumers and ensure the degree of CEBs before implementing their carbon emission reduction policies.
