摘  要:针对当前网络信息系统使用中软件问题突出、缺乏有效的软件系统可靠性指标验证方法等问题,提出了一种构件化软件系统可靠性评估方法及其实施流程。首先,通过系统任务分析和功能分解,确定了软件系统的任务构成和基本系统构件;其次,利用UML活动图建立了软件系统任务执行过程的分层业务流程模型;然后,基于构件测试数据,利用经典的软件可靠性模型、 Markov过程方法和加权平均法对构件化软件系统的可靠性进行了评估;最后,以某网络信息系统为例,开展案例应用研究,对所提出的方法进行了验证,证明了该方法的可行性,为软件系统和网络信息系统的可靠性指标确定和考核提供了技术和方法支撑。In view of the outstanding software problems during the use of network information system at present and the lack of effective software system index verification methods, a reliability evaluation method of component software system and its implementation process are proposed. Firstly, through the system task analysis and function decomposition, the task composition and basic system components of the software system are determined. Secondly, the hierarchical business process model of the task execution process of the software system is established by using the UML activity diagram. Then, based on component test data, the reliability of component software system is evaluated by using classical software reliability model, Markov process method and weighted average method. Finally, taking a network information system as an example, a case study is carried out, and the method proposed is verified, and the feasibility of this method is proved. It provides technical and method support for determing and checking reliability index of software system and network information system.
