With the development of science and technology and improvement of material , the reliability of industry products becomes increasingly higher . some life tests result in few or no failures . in such cases , it is difficult to assess reliability with traditional life tests which only record time - to - failure 现有可靠性理论对产品进行可靠性评估,须依据产品的失效数据进行,然而,随着产品的可靠性越来越高,寿命越来越长,在允许的时间内很难获取足够的失效数据。
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。
Along with the deeper study on the reliability testing and testing equipments , varieties of testing methods and fail data emerge as the times require , naturally the former analytic method would probably not satisfy us when the condition changes . the inapposite statistical arithmetic would clag the development of reliability technology undoubtedly 在电器可靠性技术领域，随着对电器产品可靠性试验及其装置深入的研究，各种不同的试验方法及不同类型的失效数据应运而生，继续沿用以往的失效数据分析方法将可能不会得出令人满意的结果，因此能否寻找出适合的数理统计方法将是制约可靠性研究的一个瓶颈。
