| 摘 要： | 考虑两同型部件组成的并联可修系统,每个部件有两类故障状态,部件故障后修理有延迟,且修理设备在修理故障部件的过程中也可能发生故障.假定部件的寿命和修理设备的寿命服从指数分布,部件发生故障后的修理延迟时间、修理时间和修理设备故障后的更换时间均服从一般分布,利用马尔可夫更新过程理论和拉普拉斯变换工具,求得了系统有关的可靠性指标.

Two Types of Failure Units Paralleled Repairable System with a Replaceable Facility and Delay Repair |
| |
| Abstract: | This paper considers a two-same-unit paralleled repairable system with a replaceable repair facility and delayed repair,in which each unit has two types of failure and will not be repaired at once when it appears one of failures.Under assuming that both the life of each unit and the repair facility's life have exponential distribution,and the repair time,the delayed repair time and the replace time of the repair facility have general distribution,we discuss some reliability problems of the system by using Markov renewal process theory and Laplace transform tool.A series of reliability results of the system are obtained. |
