摘　　要：针对闭环供应链中销售渠道结构的最优选择问题,考虑市场需求和回收品质量水平的不确定性,以总利润最大化为目标,构建了政府差别权重补贴下四种销售渠道结构闭环供应链系统的四个平均总利润模型。首先运用模糊机会约束规划(FCCP)法将模糊约束等价变换为清晰对应式,然后采用粒子群优化(PSO)算法和遗传算法(GA)对模型算例进行对比求解,最后对参数进行了灵敏度分析。结果表明,上述两种算法的差值比率最大为0.018%,表明两种算法均未陷入局部最优解,验证了算法的效度和模型的信度。企业可以根据潜在需求的不同置信水平制定最优回收、生产和销售策略,选择最优的渠道结构并逐渐提高总利润。Aiming at the optimal choice of sales channel structure in the closed-loop supply chain,considering the uncertainty of market demand and quality level of recycled products,four average gross profit models for the closed-loop supply chain system with four sales channel structures under the government differentially weighted subsidy were constructed with the objective of maximizing the gross profit.Firstly,Fuzzy Chance Constrained Programming(FCCP)method was used to transform the fuzzy constraints into clear corresponding expressions equivalently.Then,Particle Swarm Optimization(PSO)algorithm and Genetic Algorithm(GA)were used to solve numerical examples of the model comparatively.Finally,sensitivity analysis was performed on the parameters.The results show that the maximum difference ratio of the above two algorithms is 0.018%,indicating that both algorithms do not fall into the local optimal solution,which verifies the validity of the algorithms and the confidence of the models.Enterprises can formulate optimal recycling,production and sales strategies according to different confidence levels of the potential demands,choose the optimal channel structure and increase the gross profit gradually.
