基于层次和数据流驱动的软件可靠性分配方法

摘要

This paper proposed a software reliability allocation method based on hierarchy and data flow driven to improve the effective of software reliability allocation.The method improved the traditional software importance and complexity measurement model.It defined the architecture abstractly with the system module hierarchy relationship and data flow relationship in the software system development initial phase.It established the reliability factors measurement standards and measurement model,and reliability was allocated based on the measurement model.Finally,it verified the method by the example.The results show that the allocation method is effective and feasible.%为了提高软件可靠性分配的有效性,提出了一种基于层次和数据流驱动的软件可靠性分配方法.该方法对传统的重要度、复杂度度量方法进行改进；针对软件系统开发初期体系结构中系统模块层次关系及模块间数据流关系进行抽象,形成体系结构形式化定义,建立可靠性因子的度量准则及度量模型,依据度量模型对可靠性进行分配.最后结合实例进行了分析和验证,结果表明了该分配模型的有效性和可行性.
