数字图书馆云计算平台可生存性定量评估的指标体系

Index System of Quantitative Evaluation for Cloud Computing Platform Survivability of Digital Library

为有效评估数字图书馆云计算平台的可生存性,论文提出了一种定性分析与定量计算相结合的,能系统反映云计算平台可生存性的指标体系,并进行了详细描述和数学模型。分析与验证结果表明,该指标体系具有规范性、完备性特点,对信息系统可生存性的定量评估具有指导意义。

In order to evaluate the survivability of cloud computing platform of digital library, it proposes an index system with qualitative analysis and the quantify calculate, which can present the survivability, formalizes the index system, and gives the mathematical model of index system. Analysis and validation results show that this index system has the features of standardization and completeness, it is significant to quantitative evaluation for information systems survivability.
