摘要
研究修理工多重延误休假,且具有三种状态的退化可修系统。假设系统的第一种故障能够"修复如新",且第二种故障"修复非新"。以系统的故障次数N为更换策略,运用更新过程和几何过程相关理论,得出系统的平均费用率和平均维修时间的相应表达式,数值算例验证了所得结果的存在性。
Consider a repairable system with three states and its repairman having multiple delay vacations.It is assumed that the first kind of failure of system after repair can be ＂as good as new＂,the second kind of failure of system after repair cannot be ＂as good as new＂.The replacement policy is considered based on the failure number of the system.The expressions of the average cost rate C（N） and the average repair time R（N） are derived by using geometric process theory and renewal process theory.Finally,the existence of the results is illustrated through a numerical example.
