摘要
提出了一套软件可靠性衡量体系,重点研究了衡量体系中的软件可靠性建模和软件可靠性评估方法。研究了适用于软件测试阶段的Musa模型以及模型的使用前提条件、模型表示、数据要求和参数估计;同时针对软件可靠性评估的主观性和受多因素影响的特点,提出采用模糊综合评判法进行评估,给出了评估步骤和方法;最后通过实例说明如何进行可靠性建模和评估。
The paper describes a weighed system for software reliability,focusing on software reliability modeling and evaluation.The software model called Musa that is suitable for the phase of software testing and its applying prerequisite are studied,as well as model expression,data requirements and parameter estimation.Because of the fact that the evaluation of software reliability is subjective and influenced by many factors,fuzzy synthetic evaluation is brought forward.The evaluating steps and methods are presented.At last,reliability modeling and evaluation are illustrated by instance.
