基于随机网络的平均维修保障服务时间分析

摘要

The paper establishes the maintenance support process model under different support forms taking advantage of stochastic network modeling method in stochastic project analysis.It analyzes maintenance waiting time and maintenance waiting probability,establishes the mean maintenance support service time analysis model of maintenance entity.Finally, it applies the method to accompanying repairing process, and analyzes its mean maintenance support service time.%利用随机网络建模方法在随机工程项目分析中的优越性,建立了不同保障方式下的维修保障过程模型.重点对网络活动中的维修等待时间和维修等待概率进行了分析,利用随机网络的解析算法,确定了维修力量的平均维修保障服务时间分析模型.最后将该方法应用于伴随修理过程,对其平均维修保障服务时间进行了案例分析.
