摘要
模糊多属性决策中,决策者对于不确定性不同的偏好,会产生对模糊数不同的排序,因而会导致不同的决策结果。为此,在考虑决策者对于不确定性的偏好特性后,给出了决策者的不确定偏好模糊效用函数,并在此基础上提出了一种模糊数的比较和排序的新方法。通过具体的算例,说明了这种方法正确性。
According to the issue that most multi-attribute decision making problems do not reflect the effect of decision maker's subjective preferences on decision results, this issue is studied by transforming decision fuzzy numbers into utility fuzzy numbers based on utility theory and uncertainty analysis theory. A new fuzzy multi-attribute decision making method is suggested. Numerical illustrations prove that mis method is effective.
