考虑自检与修复性维修的可靠性建模及算法研究

System Reliability Modeling and Algorithm Research Considering Self-Check and Repairable Maintenance

由于传统可靠性模型的局限性,本文针对考虑自检和修复性维修的系统中,系统故障发生、检测与修复的时间相关特性,提出了最小割集法、马尔科夫法两种系统可用性建模方法,对具有自检及修复性维修系统的可用性进行分析评估,并对分析结果进行了对比,克服了传统可靠性模型的不足。并使用具备自检与可修特性的产品实际案例用于可用性分析评估,验证了模型的适用性和有效性。

Due to the limitation of the traditional reliability model, this paper focuses on the system of self-check and repairable maintenance, studies the time-dependent characteristics of system fault occurrence, detection and repair, and proposes two modeling methods of system availability, namely, minimum cut set method and Markov method. The usability of the self-checking and re-pairing maintenance system is analyzed and evaluated, and the analysis results are compared to overcome the shortcomings of the traditional reliability model. Finally, a practical product case with self-checking and repairable features is used for usability analysis and evaluation, which verifies the applicability and effectiveness of the model.
