| Abstract: | Based on paper 1],this paper considers some reliability quantities of the repair facility in the two-unit same cold standby repairable system with a replaceable repair facility and delay repair,in which the failure time of unit is assumed to follow exponential distribution,and the repair time and delay time of failed unit are assumed to follow arbitrary distributions,whereas the failure and replacement time distributions of the repair facility are exponential and arbitrary.The generalized busy period of the repair facility is defined,and a new approach to analysis the reliability quantities of the repair facility are presented by using renewal process theory and total probability decomposition. Some reliability results,such as availability and failure number,are obtained. |
| Keywords: | Operations research repairable system delay repair availability failure number generalized busy period |
