A linear programming model is proposed to find the solution of the top optimization weight vector and a decision making method is determined by the comprehensive fuzzy expectation value of plans.
针对只有部分属性权重信息,而属性指标表示形式多样的多属性决策问题,给出了把属性指标表示为梯形模糊数的方法；并提出了通过一个线性规划模型求解最优权重向量,把方案的综合模糊期望值,用以确定方案的优劣次序的决策方法最后,通过实例表明了该方法的实用性和有效性。

Considering the error in survey data,this paper presents a bi-level programming model with fuzzy expected value model as upper-level,which objective is minimum difference between estimated and measured link flow,and a user equilibrium assignment model as lower-level by taking link counts as fuzzy number.
考虑调查数据存在的偏差,将路段流量视为一个模糊数,在此基础上构造一个OD反推的双层规划模型,其上层为一模糊期望值模型,即以路段计算流量与实测流量的偏差模糊期望值最小为目标;下层为用户平衡分配模型。
