摘    要:为了解决维修间隔期确定的难题,建立了维修间隔期和总停机时间之间关系的目标函数,以及时间延迟维修模型.根据故障记录数据和预防维修活动的检查数据,采用最大似然法估计有关缺陷发生率和时间延迟分布等参数.在所建立目标函数和估计参数的基础上,计算出最优的维修间隔期.

关 键 词:时间延迟  预防维修  参数估计  模型

Abstract:To solve the problem of determining the preventive maintenance interval of production plant,target function is proposed to describe the relationship between the total downtime and the preventive maintenance(PM) interval,and a delay time model is presented.The model developed is fitted to the maintenance data of recorded failures and the number of defects identified at PM.The parameter values of the process during which defects arise and of the delay time distribution are estimated using the method of maximum likelihood.Based upon the estimated model parameters and target function,an optimal inspection interval of PM is identified.
Keywords:delay time  preventive maintenance  parameter estimation  modelling
