嵌入式系统软件可靠性模型的研究

Research on Embedded System Software Reliability Model

针对嵌入式系统中软件和硬件密切相关,都会导致软件故障这一问题,提出了一种考虑硬件相关的软件可靠性模型,并利用MATLAB软件对真实的项目数据进行仿真实验,结果表明:新模型随着测试的进行对实际数据的拟合性能比传统模型好.该模型提供了更准确的软件可靠性估计,能够帮助人们在嵌入式软件早期测试阶段制定出更好的的测试策略.

According to the problem that software and hardware in embedded systems are related to each other, and both can lead to software failures , a software reliability model related to hardware considerations was presented .After the simulation experiment on the real project data using MATLAB software , the new model showed better performance to fit data than the traditional .The model provided more accurate estimation of soft-ware reliability .It can help people to develop better test strategy in the early stage of embedded software testing .
