Abstract: The artificial factor is important for effectiveness, reliability and mean life of the stable state of the transport system. The differemtial equation of the state transition has been created in this pqper based on the homogeneous Markov process. The system state probability and measure of reliability has been solved with Iaplace transform. At the end of the paper, we estimate the mean time to failure of the vehicle.

Key words: vehicle state, stable state effectiveness, Markov process, mean time to failure

摘要： 在研究车辆运行状态有效性时,人为因素对系统的稳态有效度、可靠度和平均寿命有较大影响。本文在考虑人为可靠性因素影响下,建立了基于齐次马尔可夫过程的状态转移微分方程,由拉普拉斯变换解出系统稳态概率和可靠度,并估算出车辆平均失效时间。
