首先分析了传统的模糊决策理论的不足，提出了一种基于模糊重心的多目标方案决策方法，该方法能利用评测专家所给的模糊区间分，从而既方便了评测专家表达其评测意见，又充分利用了专家的评测意见，因而有利于提高决策的准确性.

In this paper, the shortcomings of the traditional fuzzy decision theory are discussed.A new multiobjective decision method which is called gravity center based decision method is introduced.That gravity center based decision method makes use of the fuzzy interval mark given by evaulation experts to finish plan evaulating, therefore,it is very convenient for evaulation experts to give their evaluation information and the information given by them is used fully. It is of benefit to the trusth and accuracy of the decision.
