摘要
论述了运用两种NHPP增长型模型进行某测控系统软件可靠性预计的方法,以及它们的数学解析式,并阐明了两者的关系。针对某发射测控系统软件的测试调试过程,初步估计了软件的程序容量,根据所得到的数据,运用两种NHPP模型计算了模型参数的估计值,预测了软件的可靠性水平和需要进行的各项软件测试的时间。
The reliability prediction methods for a system software with two NHPP growth models were discussed. The matematic analysabal equations for the two NHPP models were presented, and the relationship between them was explained. Based on the initial prediction of the program capacity of a system test control software, the predicted values of model parameters were calculated with the two NHPP models, and the reliability level and test time needed for the software were predicted.
