| 1. | Among various srgms , the srgm of the type of the non - homogeneous poisson process ( nhpp ) is very important , which absorbs most researches and are applied widely . such a model generally assumes that the testing environment and the operating environment of software are same , namely , the failure data of software obtained in the testing environment can predict the reliability of software in the operating environment 非齐次泊松过程( non - homogeneouspoissonprocess ,简称nhpp )类软件可靠性增长模型是软件可靠性增长模型中非常重要的一类,也是目前研究最多、应用较广的一类模型,这类模型一般假设软件的测试环境与软件的运行环境相同,即用软件在测试条件下获得的失效数据能够预测软件在运行时的可靠性。 |
