摘　　要：为了生成自动飞行控制系统软件可靠性测试数据,建立了软件可靠性的测试剖面、环境剖面等概念,提出了基于任务剖面的测试剖面生成技术和由测试剖面生成测试数据的方法,即将输入数据分为系统模式数据和环境数据,并在任务剖面下分别形成系统模式剖面和环境剖面,最后将两种剖面合成为测试剖面;将环境数据分解为控制分量和随机分量,再利用仿真的方法生成控制分量,从而生成复杂关联的测试用环境数据.通过对飞机执行任务的软件测试表明,所提方法能更为准确地描述软件的实际使用情况,其描述方式与硬件可靠性试验较为类似,可作软硬件系统综合的可靠性试验的基础.In order to generate software reliability test data for automatic flying control system software, some new concepts of software reliability including test profile, environmental profile are established. The generating technique of test profile from mission profile and the generating method of test data obtained from test profile are developed, i.e. the input data is classified as the system mode data and environmental data, then system mode profiles and environmental profiles are formed under the mission profile respectively. Furthermore, the two formed profiles are combined as a test profile. The environmental data are decomposed into controlled components and stochastic components, and the simulation method is reused to generate the controlled com- ponents to produce the environmental data for the complicated association test. It is shown that the proposed method can describe the practical cases of software application more accurately with a similar way to describe the reliability test of hardware, and can be regarded as a reliability test foundation for synthesizing hardware and software systems.
