| 摘 要： | 软件可靠性模型是评估软件可靠性的重要工具，由于受一些不为模型所控制的随机因素的制约，软件可靠性评估结果中往往含有大量的误差，给工程应用带来许多困难。在对现代计算机应用系统的故障特征、软件可靠性模型的机理及引起误差的因素进行深入分析的基础上，提出了一种误差分析法，并用之校正软件可靠性模型的评估值。

| Abstract: | Reliability model is an important tool used to estimate the reliability of software. However, because of some random factors, which are not discussed in these models, models can not estimate software reliability accurately. And of course, model application in industry is barred. This paper first discusses the failure characteristics of modern computer application system, the fundamental method of software reliability models and random factors that cause deviation, then presents a useable approach to analyze deviation and assist software reliability estimation. |
