【摘要】 随着软件应用的越来越广泛,计算机软件的可靠性变得越来越重要,据统计,在硬件软件混合系统中,系统失效的主要原因来源于计算机软件的失效,因此,系统中的软件的可靠性是提高系统可靠性的一个重要因素。尽管软件可靠性模型有很多,但是,由于这些模型是建立在一系列难以验证正确性的假设之下,因此限制了这些模型在实际中的应用,造成了软件可靠性参数计算上的困难。本文在提出了一种基于软件功能结构的软件测试数据分组方法,在此基础上,提出了一种基于软件功能问依赖的软件可靠性参数评估方法。更多还原

【Abstract】 According with the widely used of software, the reliability of the software is becoming one of the most important thing. In a system that mixed with hardware and software, the main reason of the system failure is the software failure. A lot of reliability modules have been used to evaluate software reliability, but it is difficult to use these modules correctly and easily because the conditions to theses modules are very difficult be verified. In this paper, a cluster of the test data based on the function structure is put forward, then, an reliability evaluate method on the dependency between the function components of the software is given.更多还原
