摘　　要：考虑碳配额差值对产供销一体化系统中的选址-路径-库存集成问题的影响,构建了嵌入碳配额差值和选址-路径-库存运作成本的非线性整数规划模型,并对模型中的碳配额差值和选址-路径-库存运作成本两个目标同时进行优化;通过对目标函数进行等价处理,设计了基于BFA-PSO的组合优化求解算法;数值仿真结果显示企业可以通过运作层的决策优化,以较小的经济成本获得较大的碳减排绩效。Recent years the great effect of economic activity on environmental degradation has been witnessed. Many policies have been made to control the carbon emissions, and the best-known is the Kyoto Protocol, The carbon emissions are gradually translated into regulations, which will put some press on the supply chain members. For another, some enterprises with social responsibility have engaged in the voluntary emission reduction programs, for example, company such as BP and Nike have took some actions on reducing emissions to improve their public image. However, reducing the carbon emissions of supply chain＇s operations provides a huge opportunity. As we know, location, routing and inventory are the key drives of cost and carbon emissions; the collaboration of them is the focus of this paper. The 3-stage supply chain network consists of plants, potential RDCs, and DCs. The carbon cap CCAP is from the regulatory organization, and the actually emissions are CEL , CER and CE1 from location, routing and inventory, respectively. So the carbon-capped difference （CCD） is CEL ＋ CER - CER - C^CAP . If the CCD is negative, the supply chain members must buy the carbon credit from the carbon market to make up the shortage; else, they can make a profit on the redundant carbon cap. The buying carbon emissions e^＋ and selling carbon emissions e^- must satisfyCEL＋CER ＋CE1＋e^-≤C^CAP ＋e^＋ . When the cap and trade mechanism conducts, the CCD can translate into money. Given that premise, the collaboration of location-routing-inven- tory model is presented. The aim of this paper is to find an optimal decision minimizing the cost and emissions in supply chain operations. The combinatorial optimization BFA-PSO algorithm is presented to obtain the optimal solution of the proposed model. The case study from part of the northeast petrochemical sales company of CNPC has verified the validity and practicability of the model and algorithm. To compare the effect of CCD on the results, the solutions of joint optimization are
