摘　　要：在讨论当前使用的软件可靠性模型存在的主要缺陷的基础上,提出了一个新的软件可靠性模型.当今应用模型中的可靠性假设条件并不考虑软件本身的复杂性、软件测试的有效性以及软件应用环境的完全性等要素,因此在评估软件可靠性时往往产生不精确的结果.为此将尽可能多的与被测软件可靠性评估有关的因素,结合到软件可靠性模型中去,使得对被测软件的可靠性模型更切合实际,因此使它更为精确.以一个实际的软件测试实验及对该软件进行的可靠性评估为实例,说明所提出观点和方法的合理性和可行性.The major weaknesses of the software reliability models currently used are discussed and a new software reliability model is proposed.For the time being,the assumptions that software reliability measurement do not deal with the complexity of most software,the effectiveness of test suite and the complete operating environment,resulting in inaccuracy or even incorrectness in evaluating the software reliability.The central idea of the strategies proposed is to incorporate as many influence factors such as complexity of the software under test as possible so as to make the software reliability models more adequate and accurate towards the real situation.Results from substantial experiments have shown the rationality and usefulness of the new model proposed.
