摘要
模糊数是群决策中常用的决策结果表达形式.研究了模糊群决策结果的可信性评估问题.认为群决策结果的可信性与模糊群决策结果的模糊度和一致度存在强相关,因此,模糊群决策结果可信性评估主要就是对群决策结果的模糊度和一致度的计算,创新提出了基于群隶属函数的模糊度和一致度的计算方法,并给出了基于模糊度和一致度的专家模糊数决策结果综合评价值的计算方法,最后,在此基础上求得专家模糊评估结果的可信度和群决策结果的可信度.
Fuzzy number is commonly used in Group Decision Making（GDM）. Research on the evaluation of credibility of fuzzy result of GDM is done in this paper. There is a strong relation between the credibility of result of GDM and fuzzy degree or consistence of result of GDM. So evaluation of credibility can be done based on fuzzy degree and consistence of result of GDM. A novel method based on fuzzy degree and consistence is proposed. Finally, the credibility of experts and credibility of result of GDM can be available.
