摘　　要：针对可信云服务评估问题,提出一种区间犹豫模糊灰色可能关联分析(IVHF-GLRA)决策方法。首先,提出了区间犹豫模糊灰色可能关联系数概念,进而基于Choquet积分介绍了一种非加区间犹豫模糊灰色可能关联测度;此外,提出了一种新的用于测度区间犹豫模糊元不确定性的熵测度公式,并将其用于确定决策准则间的权重系数。在此基础上,发展了一种用于可信云服务评估的区间犹豫模糊决策方法并进行了实例分析,分析结果表明所提方法科学且有效。Aiming at the problem of trusted cloud services evaluation, this paper put forward a method named interval-valued hesitation fuzzy grey likelihood relation analysis （IVHF-GLRA）. Firstly, it put forward the concept of interval-valued hesitate fuzzy grey likelihood relation coefficient, and then introduced a non-additive interval-valued hesitate fuzzy grey likelihood rela- tion measurement based on the Choquet integral. In addition, it proposed a new entropy formula to measure the uncertainty of interval-valued hesitant fuzzy set, and it was used to determine the weight coefficient of decision criteria. On the basis of these, it developed a new method for the evaluation of trustworthy cloud services, and gave an example. The results show that the proposed method is scientific and effective.
