Abstract

Consider a two - echelon repairable INVENTORY system consisting of a central depot and multiple stocking centers. There are two kinds of defectives, both of them must be repaired at central depot. The difference between these kinds of defectives is related to their depot replenishment lead times. The centers provide parts replacement service to customers and the depot fills each kind of center replenishment orders on a FCFS (First Come First for Service) basis defective parts that are received by centers are passed to the depot for repair and depot INVENTORY replenishment. For this system, existing models (for example, METRIC model) usually assume that there is only one kind of defective, and they also assume that the depot replenishment lead times (DRLTs) are i.i.d, which however, does not fit well into the service part logistics system, that motivated this research. Because the DRLTs consist of the sum of repair times, defective return times and transportation times, they are different across stocking centers, which are located globally. We study the impact of such center - dependent DRLTs on system performance. We show that for such systems, using the i.i.d DRLT assumption introduces errors in estimating system performance.
