摘要
提出带失效因子的J-M软件可靠性预计模型。先分析了原有J-M软件可靠性预计模型的特性,指出了此模型产生与实际情况差异的原因;基于在测试初期软件出现的错误,对软件失效率的影响大于测试后期出现的错误对软件失效率的影响的思想,提出了带失效因子的J-M软件可靠性预计模型。最后,针对所提出的模型,利用测量的数据进行了实际验算。
A kind of J-M software reliability prediction model with disabled factor is put forwared in this paper. Firstly,the performance of the original J-M software reliability prediction model is analyzed,and the difference between the original model and the real environment is pointed out. Secondly, based on the idea that the influences of error on the earlier stage test on the software disabled rate overceed that on the later,a kind of J-M software reliability prediction model with disabled factor is presented. At last,checking computations are operated on the original and the presented models.
