| Abstract: | A two different components and two repairmen of a cold standby system with delay repair are studied.Assumed that the working life of components is subject to general distribution,and the delay fault repair time and repair time are exponential distributions. By using Markov renewal process,the Laplace transform and the Laplace-Division ladder transform,the system reliability indices such as the first failure time of system,availability and the average failure frequency are obtained. |
