摘要/Abstract

摘要：

用户评分的模糊性、随机性表现出服务质量(QoS)的不确定性是软件即服务(SaaS)最优服务选择研究的难题之一.提出一种基于云模型的SaaS服务决策方法(SDM_CM)以解决上述难题.该方法首先使用逆向QoS云发生器将评分描述的QoS指标转换为云模型描述的QoS指标;接着借鉴多属性决策分析中常用、有效的多属性决策算法-优劣解距离法(TOPSIS),提出基于云模型的SaaS最优服务决策算法.最后,在真实的服务质量数据基础上,验证了该方法的优越性和有效性.

关键词: 云模型, 软件及服务, 用户评分, 不确定性, 优劣解距离法

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-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 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 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.

Key words: cloud model, software as a service (SaaS), user rating, uncertain, technique for order preference by similarity to an ideal solution (TOPSIS)
