摘要

—In this paper, the instantaneous availability models in continuous and discrete time are proposed for the one-unit repairable systems with delay under exponential distributions. Prior to this, error analyses of sampling discrete distributions are given. Then, the numerical solutions for the continuous- time model and the discrete-time model are presented. The comparison of the solutions reveals that with the step length and sampling interval decreasing, the accuracy of the numerical model is much better. Also, in the same accuracy level, less computation time is needed to solve the discrete-time model. Hence, the discrete-time model is more feasible to analyze instantaneous availability. Finally an example is given to describe the application of the results.
