摘要
研究了n个独立但不同分布的元件构成的一类并联系统的剩余寿命和平均剩余寿命,即在t1时刻有l个元件失效,第κ个元件的寿命恰好是t2(0≤l<κ<n,0≤t1<t2),系统在t2 时刻仍然工作的条件下并联系的可靠性函数和平均剩余寿命。
This paper investigates a new residual life function and mean residual life function of parallel system consisting of n independent and nonidentically distributed components.Givens that the total number of failures of components is not less than l at time t1,the life of κ th component is t2(0≤l<κ<n,0≤t1<t2),and the system is still working at time t2.
