软件错误及其对工具系统—WPADT的影响

软件错误及其对工具系统—WPADT的影响 SOFTWARE ERRORS AND THEIR INFLUENCE UPON DEVELOPMENT OF TOOL SYSTEM—WPADT 何克清 He Keqing and Xu Renzuo first-author 徐仁佐 在软件工具系统——WPADT的开发过程中, 我们收集了一些错误数据。本文对它们进行了分析,并报导了分析的结果;讨论了在软件开发过程中,收集错误数据的方法及存在的困难问题;定义并计算了WPADT的平均每千条可执行语句行的控制复杂度,并据此得出它与模块大小基本上成线性增长的结论。最后,运用Nelson模型对WPADT的可靠性作了粗略的估计。 Some error data collected during the development of a medium-scale software tool system—WPADT（Wuhan University Problem Analysis Diagram Translator）. An analysis and the results of this analysis are given in this paper. The analysis includes: module size categories, the relationship between module size and proneness of software errors, effort to correct errors, error disribution by error types, etc. This paper analyzed the type of error proneness, the relationship between correcting and proneness of software errors, the relationship between correcting and some specific error types, etc. Besides, this paper discussed the difficulties and the method to collect the error data and analyzed statistically the error data collected during the development of WPADT. Finally, introduced the theory of Nelson’s model and applied the model to the estimation of reliability of WPADT roughly. 1986-02-01 2021-04-01 2
