Abstract: For effectively eliminating the difficulties in the cloud computing deployment plan evaluation caused by the conflict between the attributes of resources and the coordination between user requirements,an interval hesitant fuzzy double compromise evaluation method was proposed.Considering the distinct advantages of VlseKriterijumska Optimizacijia I Kompromisno Resenje (VIKOR) and Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) methods that the former for solving the conflict of indicators and the latter for balancing the positive and negative ideal solutions,based on following the ideas of “overall utility” and “maximum individual regret” of VIKOR,a negative ideal solution based compromise aggregation mechanism was defined with the core of “overall punishment” and “maximum individual reward”.Based on modifying the distance measurement for interval-valued hesitant fuzzy elements,a double compromise comprehensive evaluation method was designed,which could not only reflect the compromise between the overall and the extreme individual indicators,but also cope with the situation that the values and the weights of indicators all were interval-valued hesitant fuzzy.The designed method was used to a practical case of cloud computing deployment plan evaluation,the evaluation results and some comparative analysis validated the adaptability and rationality of the method.

Key words: technique for order preference by similarity to an ideal solution, vlsekriterijumska optimizacijia i kompromisno resenje, double compromise, interval hesitant fuzzy set, evaluation of cloud computing deployment plan
