大型机载信息化系统软硬件一体化可靠性鉴定试验方法及其应用

Research on the Integrated Reliability Qualifi cation Test Method and Its Application for Hardware and Software in Large Airborne Information System

针对目前大型机载信息化系统的软件可靠性越来越重要,而传统可靠性鉴定试验无法考核系统软件可靠性,软件可靠性测试无法考核综合环境应力下的软件可靠性,以及软硬件一体化可靠性指标考核的问题,提出了大型机载信息化系统软硬件一体化可靠性鉴定试验方法解决这一问题的设想。该方法综合考虑了传统可靠性鉴定试验和软件可靠性测试的优点,并详细给出一种大型机载信息显示和控制系统的应用实例,充分地分析论证了该方法的可行性和科学性。

Software reliability plays an increasingly important role in large airborne information system, while the traditional hardware reliability qualification test fails in assessing software reliability and the existing software testing methods are considered without the combined environmental stress. To solve the problem of assessing the integrated reliability index of hardware and software in large airborne information system, an integrated reliability qualification test method was proposed. This method possesses the merits of both the traditional reliability qualification test and software reliability testing. An application example of a large airborne information display and control system was presented in details, which was a sufficient analysis and demonstration of the feasibility and scientific nature of this integrated method.
