| Abstract(in English) | The two-echelon repair system is a type of multi-echelon repair system. The maintenance facilities in the system are divided into two types. A failed item is assigned to one of two-repair facilities depending on the degree of failure and the situation. We propose an availability evaluation model of a two-echelon repair system with limited repair capacity considering the common-cause failures. It is an approximation method based on the METRIC model and an iteration method. The system in a base is a k-out-of-n system composed with identical components. The occurrence of a common-cause failure is considered to the arrival of demand that follows a compound Poisson process. We perform numerical analysis for the model to compare the availability of the proposed method to that of Monte Carlo simulation and verify the accuracy. |
