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.
在討論噹前使用的軟件可靠性模型存在的主要缺陷的基礎上,提齣瞭一箇新的軟件可靠性模型.噹今應用模型中的可靠性假設條件併不攷慮軟件本身的複雜性、軟件測試的有效性以及軟件應用環境的完全性等要素,因此在評估軟件可靠性時往往產生不精確的結果.為此將儘可能多的與被測軟件可靠性評估有關的因素,結閤到軟件可靠性模型中去,使得對被測軟件的可靠性模型更切閤實際,因此使它更為精確.以一箇實際的軟件測試實驗及對該軟件進行的可靠性評估為實例,說明所提齣觀點和方法的閤理性和可行性.

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.
