Abstract:Aimed at the decision-making problem of cloud computing adoption, a new Multi-attribute group decision-making(MAGDM) approach is proposed. First, this paper argues that cost, as well as TOE factors (Technology, Organization and Environment) should be considered for cloud adoption decisions; Second, the method of standard and mean deviation is applied to determine the unknown attribute weights, and the weights of the decision makers will be determined by using the improved TOPSIS (technique for order preference by similarity to an ideal solution) method; Finally, based on the LWAA(linguistic weighted arithmetic averaging) operator, calculate the comprehensive evaluation value and upper and lower limited value.Through compared with the calculated value and upper, lower limited value to identify whether the firm is suitable for the adoption of cloud computing. A numerical example is given to illustrate the usefulness of the proposed approach
