1) Failure times and frequency
故障频次
2) first-time fault
首次故障
1.
Some concepts such as reliability, first-time fault, average life-span and crowed number,are derive.
在此方法中,只要确定了系统的首次故障平均时间θ和故障密度的众数θmax,就能确定系统可靠度的两个特征参数λ和m,从而确定可靠度的具体表述。
3) failure number
故障次数
1.
Supposing that the repair after the system failure is not "as good as new",we consider replacement policy based on the failure number for the system,by using renew pro.
假设系统每次维修后均不能"修复如新"时,以系统的故障次数为更换策略,通过更新过程和几何过程理论,求出了系统经长期运行单位时间内期望效益的明显表达式。
2.
The expected failure number during a given(0,t ] and the stead-state failure frequency are studied,and some important reliability results are obtained.
考虑一种新型的可修系统,即修理设备可以修理的单部件系统,通过引入“广义修理时间”的概念,在假定部件的寿命服从一般分布的条件下,通过适当的假设,讨论了系统的瞬时可用度和稳态可用度,以及(0,t]时间内系统的故障次数和稳态故障频度,得到了一些重要的可靠性结果。
3.
In the paper, the stochastic process of the failure number is studied in following the line of modelling the dynamic equation for the failure number on the basis of the distribution of the failure time.
依据设备故障间隔期的概率分布，研究了设备故障次数的随机动态变化过程，建立了随机性分析的递归方程，并进一步研究了基于设备故障次数及其概率的最小费用周期更新模型，还采用一个模拟例题做了基本验
5) minor failure
次要故障
6) gradual failure
渐次故障
