After a report of results about infinite servers queues, essentially on its busy period, a model is built, using networks of queues with infinite servers in each node, to study a two echelons repair system for example of a fleet of aircraft , of shiping or of trucks. The costumers are the failures. And its service time is the time that goes from the instant at which they occur till they are completely repaired. The failures repairs occur in a base or in a remote station. The whole failures detected in the base are repaired there. Some of the failures detected in the station are repaired there and the others in the base. The results referred above allow the determination of a two echelons repair system performance measures. In this application models of Carrillo (1991) and Ferreira (1996) are considered, improved and completed. The theory is illustrated with a numerical example.
