针对可信软件可靠性定性评估问题,将云模型理论与GB/T16260中软件可靠性度量指标相结合,提出了一种基于云模型的软件可靠性度量模型。模型根据可靠性度量指标提取样本信息,通过云发生器生成云模型,运用合并云算法将多个属性云合并为一个综合云模型,使用带权重的欧氏距离云决策算法确定综合云模型的可靠性等级。通过某安全关键软件验证,该模型能够更加客观、真实地反映软件的可靠性。
This paper combined the cloud model theory and the software trusted reliability measurement of GB/T16260 ac- cording to the problem drawn from software trusted reliability. And it proposed a software trusted measurement model based on cloud model. This model can draw the sample information from the index of reliability measurement. It can generate cloud model through cloud-generator and merge the comprehensive cloud model from cloud algorithms of various attributes. The level of reliability can be confirmed from cloud decision algorithm based on Euclidean distance. The reliability of software can be re- flected more subjectively and truly through the tests of some safety software.
