摘要
为了对船舶推进轴系进行可靠性评估,提出了基于灰色马尔科夫过程的船舶推进轴系可靠性评估模型。该方法将船舶推进轴系分为若干个子系统,根据各个子系统在不同状态下的统计数据,将马尔科夫过程与灰色系统理论相结合,建立了船舶推进轴系可靠性评估模型。通过对实际船舶推进轴系可靠性指标的计算和对比,验证了该模型的正确性,从而为制定船舶推进轴系的维修策略提供了理论支持。
To assess the reliability of marine propulsion shafting, an assessment model is established by grayMarkov process. According to the approach, marine shafting system is divided into several subsystems, and thenbased on the statistics of each subsystem the model is built by Markov process combined with gray theory. Theproposed approach has been verified by the statistics data of actual operating marine propulsion shafting system.Therefore, it can provide a theoretical support to make the maintenance strategy of marine propulsion shafting.
