中文摘要：

嵌入式系统硬件的可靠性是十分重要的,它直接关系到嵌入式系统的质量和寿命。为了对嵌入式系统的硬件可靠性进行分析,利用Copula方法从硬件角度和层面对其进行研究。首先从嵌入式系统硬件的组成层面对其进行抽象定义;然后从组成嵌入式系统硬件的每个功能模块出发,对每个功能模块从软硬件综合角度进行可靠性建模,同时利用Copula函数建立了嵌入式系统硬件的可靠性模型;最后对嵌入式系统硬件可靠性模型的参数进行估计,给出具体的嵌入式系统硬件可靠性计算实例,并将所建立的模型与其他类型的Copula函数进行比较。通过实例化分析和验证结果表明,得到的嵌入式系统硬件Copula函数模型是切实可行的。

英文摘要：

The reliability of Embedded System Hardware （ESH） is very important, which is directly related to the quality and longevity of the embedded system. To analyze the ：reliability of ESH, it was studied on the perspective of hardware using Copula function. At first, abstract formalization of the ESH was defined from composition level. Then reliability modeling of each function module of the ESH was given by considering integration of hardware and software, as well as using Copulas function to establish the reliability model of ESH. Finally, the parameters of the proposed reliability model were estimated, and a specific calculation example by using this proposed model was put forward and compared with some other Copulas functions. The resuh shows that the proposed model using Copula function is effective.
