摘　　要：以搅拌—运输—摊铺系统为例 ,先后建立了高等级路面施工机械化系统的马尔柯夫模型及有效度模型 ,进而对系统处于各种状态下的概率随工作时间的变化、系统有效度随失效率、维修率的变化分别进行了分析 ,最后得出为保证系统能够连续性流水线式施工作业 ,应适当降低各子系统的失效率 。Taking the mixing transport paving system for example,the Markov model and the availability model of construction mechanization system of high grade pavement are established.Then the changes of probability which the system has in every state with the work time and the changes of system availability with the failure rates and repairing rates are analyzed.At last ,the conclusions are presented that the failure rate of every assembly should be reduced and the repairing rate should be raised properly to ensure the continuity and flow construction of pavement for the system.
