基于层次分析法的云服务可用性评价方法

An Evaluation Method for Cloud Service Usability Based on Analytic Hierarchy Process

面向云服务可用性评价的多准则决策问题,提出了一种基于层次分析法(AHP)的云服务可用性评价方法.首先,梳理了近年来国际标准化组织和国内外学者针对云服务可用性研究的相关成果;其次,结合云服务可用性的各种特性和子特性,以及企业的最佳实践,提出了度量方法;最后,将AHP引入云服务可用性评价,保证评价结果的科学性.实验结果表明,通过对影响云服务可用性的特性和子特性进行层次划分,以及对各类影响因素度量方法的合理设置,有效地提高了云服务可用性评价的标准化水平和准确性.

To solve the problem of multi-criteria decision making for usability evaluation of cloud service,an evaluation method for cloud service usability based on analytic hierarchy process (AHP) is proposed.Firstly,research achievements related to cloud service usability of international organizations for standardization and scholars at home and abroad are sorted and analyzed. Then,measurements of characteristics and subcharacteristics are proposed considering the definitions of them and the industry best practices.Finally,AHP is introduced into the evaluation process to ensure the scientificity of the evaluation result.Experiments show that the method can be used to improve the standard level and accuracy of usability evaluation of cloud service by hierarchical division of characteristics/subcharacterisitics and relative weight setting.
