现代科学证明,决策者在作决策时不可避免地要涉及大量的模糊问题,采用模糊思维方法进行决策是决策者的一项必备能力。所谓模糊思维,首先就其思维的对象而言,是关于模糊事物的理性认识。越是复杂多变的事物,模糊思维发挥作用的可能性越大。模糊思维的逻辑基础是模糊逻辑,使用模糊概念判断和模糊推理进行思维。其次,就其思维的方法而言,虽然不像精确思维那样可以作精确的定量化、完全形 Modern science has proved that decision-makers inevitably have to deal with a large number of ambiguous issues when making decisions. Using fuzzy thinking to make decisions is an essential capability of decision-makers. The so-called fuzzy thinking, first of all, the object of thinking is the rational understanding of fuzzy things. The more complex and changeable things, the greater the possibility of fuzzy thinking. The logical basis of fuzzy thinking is fuzzy logic, the use of fuzzy conceptual judgments and fuzzy reasoning thinking. Second, as far as the method of thinking is concerned, though not precisely quantifiable as precise thinking,
