Abstract: The paper studied the research status of fuzzy multi-attribute decision on the complex phenomenon.Furtherly,the fuzziness and randomness of language information and their impact on the alternatives have become the focus of current research.So,a set pair cloud multi-attribute group decision method was presented with cloud model and SPA to solve these problems.Then the method was used for the study of “new rural energy development and utilization” to establish the renewable energy development model,and the corresponding solutions was given.Finally,a active result was got with the fuzzy two-tuple linguistic analysis to compare the experimental,which shows the method is rational,effective and practical.
