A Two Stage Tandem Repairable Remanufacturing System with Work-In-Process (WIP) Inventory Control

Abstract

This paper deals with an unreliable remanufacturing system involved in the processing and remanufacturing of WIP inventory. While processing the items to be recycled, the system may become out of order followed by a two-stage tandem repair. The system capacity K is assumed to be finite. As soon as the items start entering the system and queue up to seek service, the server takes some start up time to activate and then waits to serve until the N items of WIP inventory are accumulated. Once the system becomes full, further arrival of items is not allowed until the queue length decreases to a prespecified level F. The time dependent behaviour of the system is analysed using Runge-Kutta 4'" order method. To explore the system's effectiveness, the model formulated has been tested numerically.
