摘　　要：基于人们对事物选择处于犹豫不决时,易受他人选择的影响而产生从众选择的行为特征,分析直觉模糊数的犹豫部分对得分函数和精确函数的影响,通过累加和极限方法,定义直觉模糊数的累积得分函数和累积精确函数,进而提出一种基于新得分函数和精确函数的模糊多属性决策方法.This paper puts forward that the degree of hesitance will probably play a very important role in the score function and accuracy function by considering that decision-maker easily produces herd behavior when he hesitates to make a decision.Therefore,accumulated score function and accumulated accuracy function are defined based on deeply excavating the degree of hesitance by using the method of accumulation and limit.Finally, a new method for handling multi-criteria fuzzy decision-making problems under the intuitionistic fuzzy environment is presented.
