摘要: 软件可靠性是软件质量的一个重要因素,如何提高软件可靠性已成为一个迫切的问题。本文综述了软件可靠性模型的概念和分类,详细分析了J-M模型参数方程的建立及其特性,由对方程根的判定推导出了一个切实可行的方程解法,通过与美国NASA开发的软件Smerfs的实验结果比较,可以看出方程的解法是合理的。

关键词: 软件可靠性, 软件可靠性模型, 参数方程

Abstract: Software reliability is a important attribute of software quality, and it is a urgent topic that how to improve software reliability. This article summarizes the notion and class of software reliability model, analyses the establishment of parameter equation for J-M software reliability model and gets a better way of the equation.The settlement for the equation is rational by comparing to the result of Smerfs in USA NASA.

Key words: software reliability, software reliability model, parameter equation
