| 摘 要： | 提出改进的关于软件产品的软件可靠性增长模型.分析了关于软件产品的可靠性增长原模型的特性,指出了原模型的假设与实际情况不相符的方面;在充分考虑补丁对销售后的软件产品的作用下,将Littlewood对软件模型的思想-即在测试初期出现的错误对软件失效的影响大于后期出现的错误对软件失效率的影响-引入到原模型,并提出了改进的关于软件产品的软件可靠性增长模型.针对所提出的模型,利用测量的数据进行了实际仿真.

| Abstract: | The improvement of reliability growth in software products is put forwared in this paper.Firstly,the performance of reliability growth in software products is analyzed,and the difference between the original model and the real environment is pointedt 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,the improvement of reliability growth in software products is presented.At laster,checking computation are operated on... |
