Abstract: In this paper，a minimum weighed distance model of emergency material storage location based on trapezoidal fuzzy numbers is studied.Firstly，the concept and operations of trapezoidal fuzzy numbers are given.Secondly，the model of emergency material storage location with trapezoidal fuzzy number in objective function is set up，and the solution algorithm for this model is presented.Finally，a numerical example shows the valiadity of the method.

摘要： 研究了基于梯形模糊数的应急物资储备库最小加权距离选址模型。给出了梯形模糊数的概念和运算，构建了目标函数中参数为梯形模糊数的应急物资储备库最小加权距离选址模型，提出了求解该问题α-水平最优解的算法，最后通过算例分析说明该方法的有效性。
