摘　　要：针对属性权重完全未知且属性值为三角模糊数的多属性决策方法,所求出的所有方案综合属性值所在的区间一般并不是使用同一个属性权重向量,使得所有的方案评价不具有可比性。提出一种基于线性规划和投影模型的区间型多属性决策方法,该方法基于加权属性值离差最大化建立一个线性规划模型,通过求解此模型得到属性的权重,计算各方案的加权属性值在模糊正理想点和负理想点上的投影,进而计算相对贴近度,并据此对方案进行排序,最后,通过高校科技产业风险评价的仿真算例说明了模型及方法的可行性和有效性。According to the attribute weights being unknown completely and the attribute values in multiple attribute decision making method for triangular fuzzy numbers, all the schemes of comprehensive attributes for the values of interval general do not make use of the same weight vector of attributes and make evaluation of all the schemes incomparable. A method is proposed for interval multiple attribute decision making based on linear programming and the projection model. Based on the maximal deviation of weighted attribute values, the method is the establishment of a linear programming model. The attribute weights are obtained by solving the model, the weighted attribute value of each project in the fuzzy positive ideal projection point and the negative ideal point, and then calculate the relative closeness degree. The alternatives are, finally, used to illustrate the feasibility and effectiveness of the model and method through the simulation of the technology industry in college risk assessment example.
