摘　　要：根据船舶的系统特点,在机器设备与人员系统耦合的情况下构造了船舶人机系统的可靠性模型,应用工程学可靠性原理,考虑混合可靠性模型中的本地和远程状态,分别计算了人机系统的可靠度Rs(t)、失效率sλ(t)和系统平均首次故障时间MTTF,并对文中的各子系统的失效率敏感度作出重要性分析。According to the condition of structural characteristics of ships, the authors construct the human-machine system reliability model of ships based on the coupling situation when machine equipment combined with human systems, then consider the local and the long distance situation of the mixed system appling with the reliability principle of engineering science, the authors also calculate the reliability Rs（t）, disabled rate λs（t） and the first average malfunction time MTTF, and make an essentiality discussion to sensitivity of every subsystem＇s disabled rate, this method has provided reference to the total design of the ships system.
