基于环型复杂度的一种判断程序可靠性的统计方法

A Statistical Approach for valuating Reliability of Software Based on the Loop Complexity

软件的可靠性是软件质量的一个重要技术指标。该文采用软件蓝图描述软件结构,进而给出了基于程序图的环型复杂度的计算方法。在此基础上,建立起一个软件可靠性模型。最后通过一个例子说明了如何应用这个模型,通过潜在错误的检测和环型复杂度的计算,对软件的可靠性作出预测。

Reliability of software is one of important technical parameters for evaluating quality of software.In this paper,after introducing blueprint to describe software structure and deriving an approach for calculting loop complexity of program diagram,a model of reliability of software is established.By testing a practical software system this paper explains how to apply this model to evaluate the reliability of software by finding out potential faults and calculting loop complexity.
