摘　　要：为了解决回收量不确定情况下的回收网络设计问题,构建了一个基于模糊规划的逆向物流网络模型。采用三角模糊数来描述回收量,利用模糊统计方法计算模糊参数的隶属度,把模糊机会约束清晰化,从而将模糊规划模型转化为确定性规划模型,采用传统求解算法和LINGO9.0软件求解。以广西逆向物流网络设计为例,选择电视机、电冰箱、洗衣机、空调四种常用家用电器,分别计算模糊隶属度为0.1,0.3,0.5,0.7和0.9时,网络节点的数量、位置和物流量。研究结果表明,当模糊隶属度发生变化时,模型计算的回收量发生变化,网络节点之间的流量也发生变化;仓储中心、拆解中心的位置可能变化,而填埋场的位置没有发生变化。A model of the reverse logistic network was put forward based on fuzzy programming to solve recycling network design problem on condition that the recovery quantity is not certain.The triangular fuzzy number was used in this model to describe the recovery quantity,then fuzzy statistics method was used to compute fuzzy parameter membership,and then the fuzzy constraints are clear.The fuzzy programming model was changed into a deterministic programing model.The model was solved by traditional computation method and operations research software LINGO9.0.Taken reverse logistics network of Guangxi for an example.The numbers and locations of network nodes and the volume of logistics were respectively established when the confidence level was equal to 0.1,0.3,05,0.7 and 0.9 based on the chosen four kinds of household appliances（television sets,refrigerators,washing machines,air conditioning）.The results indicate that the calculated recovery quantity and flows of network nodes change with the varied confidence levels,and the locations of storage centers and dismantling centers may change but those of waste landfills may remain unchanged.
