In the process of software reliability analysis, the combined reliability model is presented, which can improve the suitability of the reliability models to the engineering failure data 在对典型软件可靠性模型进行研究的基础上,为了改善可靠性模型对工程软件失效数据的适用性,提出了组合可靠性模型分析的方法。
In this article, we apply em algorithm to estimating the values of the parameters of nhpp models . the estimating accuracy may be increased by this way . so the result software reliability analysis may be improved by this way too 最后本文应用文献[33]中介绍的em算法于nhpp类模型的参数估计,以提高估计的精度,从而提高软件可靠性分析的精确程度。
Analyzing reliability and components'importance of a sample of computer systems, this paper is focused on software reliability increment as the most crucial component for increasing system reliability effectively, and thus the importance of software reliability analysis and design is illustrated to increase the global reliability of systems distinctly 通过分析案例系统的可靠性和部件的重要度,揭示在软硬件复合计算机系统中软件子系统是系统可靠性增长的重要因素,说明软件可靠性分析和设计技术的研究和应用对系统可靠性的整体提高亦十分重要。
