模糊集重心法在综合评价中的应用

综合评价是各类宏观管理的重要手段，但是实践中存在下述困难１）按决策集最大隶属度定级常和采用其他方法的排序结果产生矛盾，说明现有的数学模型存在缺陷；２）模糊数学等级划分的模糊性和人们的习惯认识上的绝对性发生冲突，如何取得统一？模糊决策集重心定级法可以从根本上解决这些问题。

Application of Fuzzy Set-gravity Method for Synthetic Evaluation

Fuzzy synthetic evaluation is an important means for various macroscopic managements. However some difficults are existed in practice. 1) The class of evaluation result which is determined according to maximum membership degree of decision set frequently contradict with ordering result using other methods. It shows that defects exist in available mathematic model. 2) Fuzziness of classes in fuzzy mathematics conflict with absolute idea in people's habit. How to seek ulity? Fuzzy set\|gravity method should be advanced to solving these problems once for all.
