摘　　要：利用区间二次规划方法确定模糊综合评判中评价因素的模糊权向量 ,它的原理是 :以区间的概念为基础 ,利用区间相离度公式计算使主观偏好值与客观偏好值的总差距最小的权向量就是所求的评价因素的模糊权向量。This paper studies how to derive the fuzzy weight vector of evaluation factors in the Fuzzy Comprehensive Evaluation by means of Interval Limited Square Programming. The principal is that,on the base of the conception of Interval Number,the vector,which,by computing the deviation degree formula, makes the distance between the subjictive preference numbers and the objective prefrence numbers the shortest is the fuzzy weight vector we want. This algorithm is simple and objective gist is stronger.
