基于云模型的SaaS决策方法
SaaS Decision-Making Method Based on Cloud Model
摘要
Abstract
The optimal software as a service (SaaS) selection based on Quality of Service (QoS) is still challenging because user rating with fuzziness and randomness makes QoS uncertain and decision-making hard .This paper presents a SaaS decision-mak-ing 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 QoS criteria to the cloud model QoS criteria by using the backward QoS cloud generator .(2 ) Proposing a multiple attribute decision-making algorithm based on cloud model ,which draws on the effective and common multiple attribute de-cision-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 .关键词
