摘要
在对大型网络控制装置的可靠性检测的研究过程中,由于在使用过程中引入网络,造成控制装置不稳定,用传统的算法进行可靠性检测时控制装置失效率较高,存在检测误差大的问题。为解决上述问题,提出了一种采用MARKOV算法的大型网络控制装置的可靠性检测方法。上述算法融合于层次分析法的理论思想,从控制装置可靠性的角度出发,利用大型网络控制装置失效判据组建大型网络控制装置可靠性模型,用MARKOV算法计算网络控制装置的可靠性状态参数,依据得到的可靠性状态参数,建立大型网络控制装置的可靠性检测矩阵,进而精确的完成了大型网络控制装置的可靠性检测。仿真证明,基于MARKOV算法的大型网络控制装置的可靠性检测精确度高,鲁棒性强。
This paper proposes a reliability detection method for large- scale network control device based on MARKOV algorithm. The algorithm is fused into the idea of analytic hierarchy process（ AHP）,from the reliability perspective of control device. The failure criteria are used to create the reliability model of large-scale network control device. MARKOV algorithm is used to calculate the state parameter of reliability of network control device. Based on the obtained state parameter of reliability,the reliability detection matrix of large-scale network control device is constructed,so as to accurately complete the reliability detection of the large-scale network control device. Simulation results show that the proposed reliability detection method has high accuracy and strong robustness.
