研究了修理工可进行多重休假的带有一个冷贮备部件的Gaver并联可修系统.假定部件的工作时间服从指数分布,修理时间和修理工的休假时间均服从一般连续分布.利用向量Markov过程理论和Laplace变换的方法,求出了系统可靠度的Laplace变换,系统首次故障前平均时间的表达式,系统的稳态可用度和稳态故障频度等可靠性指标;此外,还通过数值比较考察了系统参数对系统稳态可用度的影响,并对系统进行了效益分析. The Gaver parallel repairable system with a cold reserve component is studied, in which the mechanic can take multiple leaves.It is assumed that the working hours of the components are exponentially distributed, the repair time and the vacation time of the mechanics follow a generally continuous distribution.Using vector Markov process theory and Laplace The Laplace transform of the system reliability, the expression of the average time before the first failure of the system, the steady state availability of the system and the steady state failure frequency are obtained. In addition, the system is also evaluated by numerical comparison The influence of parameters on the steady state availability of the system and the benefit analysis of the system.
