摘　　要：燃气管网系统在发生故障时会影响供气能力,但这是一种可修复的系统,其故障率与系统的可靠性相关。在界定供气可靠度的基础上,根据燃气管网系统的状态变化类似于齐次马尔柯夫过程的特点,探讨燃气管网系统供气可靠性评价的计算模型,并选择某燃气管网进行试算。The ability of gas supply would be affected in the event of failure to gas pipe network system.But this is a repairable system with reliability problems existing.On the basis of defining the reliability of gas supply,the calculation model for reliability assessment of gas supply of gas pipeline system is discussed according to the characteristics that status changes of the gas pipeline system is similar to time homogeneous Markov process,and a trial calculation on a gas network is done by using this model.

关 键 词：燃气管网 齐次马尔柯夫过程 供气可靠度 故障率 维修率
