摘要
针对目前软件可靠性不易评估的特点,建立一种基于马儿可夫链的软件可靠性评估模型。该模型在软件运行流程图的框架下,利用一定的统计学方法,使用线性代数方法来计算软件运行流程中各个状态的概率,建立软件可靠性评估模型,从而计算软件的可靠性;最后,利用软件设计时的判别准则来判断软件是否符合需求。
There are still a lot of difficulties in the reliability assessment of software currently. In this paper, a software reliability assessment model based on Markov chain is developed. In the framework of the software running flowcharts, the probability of each state in the running process of the software is calculated using statistical methods to establish a reliability evaluation model. With this model, the reliability of the software was calculated. Finally, whether the software meets the requirements is determined based on the software design criteria.
