To improve the accuracy of the evaluation and predicting of software reliability , this paper researches on the influence of the difference of profiles on the evaluation of software reliability by starting with the difference between the operating profile and the testing profile 实际上软件的测试剖面和运行剖面是不同的,即测试可靠性和运行可靠性是有区别的。为了提高软件可靠性评估和预测的精度,本文从研究软件运行剖面和测试剖面的差异入手,研究剖面的差异对软件可靠性评估的影响。
Furthermore , this paper provides several forms of failure ratio in the operating phase taking the difference between the testing profile and the operating profile into account according to the concepts of the testing reliability and the operating reliability , then analyzes theoretically the difference between the testing reliability and the operating reliability based on the changing trends that the failure of decreasing and first increasing and the decreasing of the failure ratio , and makes a research on the influence of the two types of reliability on the software releasing time 在此基础上给出了考虑测试剖面与运行剖面差别的几种运行阶段失效率的形式,然后根据失效率递减的和先增后减的变化趋势,从理论上分析了测试可靠性与运行可靠性的差别,研究这两种可靠度对软件发布时间的影响。绝大多数软件可靠性增长模型都假设软件故障服从同一种分布。
Firstly , this paper discusses the difference between the testing profile and the operating profile , obtains the testing ratio of coverage in the testing phase and the testing ratio of coverage in the operating phase according to practically measured data , thereby describing the difference between the testing profile and the operating profile quantitatively with the testing ratio of coverage 本文首先根据测试可靠性和运行可靠性的概念,重点讨论了软件测试剖面和运行剖面的差别,应用实测数据验证得到软件测试阶段测试覆盖率与运行阶段测试覆盖率,从而以测试覆盖率量化说明了测试剖面与运行剖面的差别。
