摘　　要：基于模糊可能性理论,研究了2-型模糊供应链网络设计问题。考虑到运输费用和顾客需求的不确定性,我们用2-型模糊变量来刻画,建立了2-型模糊环境下的期望值供应链网络设计模型。当2-型模糊变量相互独立且服从三角分布时,我们将原模型转化为等价的确定模型。等价模型是一个0-1混合整数参数规划,因此可采用Lingo软件求解。最后,我们通过数值例子演示所提建模思想。实验结果证明了所建模型的有效性。This paper studies the type-2 fuzzy supply chain network design problem on the basis of fuzzy possibility theory. Because of the uncertainty about the transportation costs and the customers＇ demands, we characterize these parameters by type-2 fuzzy variables and build a supply chain network design model with expected value criterion under type-2 fuzzy environment. When the type-2 fuzzy variables are independent and triangular distributions, we can convert the original model into its equivalent model, which is a mixed-integer parametric programming model. Finally, we present an example to illustrate the modeling idea presented in our paper. The computational results verify the effectiveness of the proposed model.
