Saa S Decision-Making Method Based on Cloud Model

A Saa S decision-making method based on cloud model SDM-CM to solve the above difficulties for the first time.

Abstract

The optimal software as a service( Saa S) selection based on Quality of Service( Qo S) is still challenging because user rating with fuzziness and randomness makes Qo S uncertain and decision-making hard. This paper presents a Saa S decision-making method based on cloud model( SDM-CM) to solve the above difficulties for the first time. It includes two main steps:( 1) Converting the rating Qo S criteria to the cloud model Qo S criteria by using the backward Qo S cloud generator.( 2) Proposing a multiple attribute decision-making algorithm based on cloud model,which draws on the effective and common multiple attribute decision-making algorithm( technique for order preference by similarity to an ideal solution,TOPSIS). The last,a set of experiments demonstrate the benefits and effectiveness of our approach.
