A GERT-based analytical method for remanufacturing process routing

Abstract

This paper presents a GERT (Graphical Evaluation and Review Technique)-based analytical method for uncertainty management of remanufacturing. Four GERT-based stochastic remanufacturing process routing (RPR) models are first proposed. A remanufacturing system that consists of various process flows is then analyzed, where the probability of and the time associated with individual process are estimated. Finally, the method is demonstrated through the remanufacturing of used lathe spindles, and validated by Arena simulation.
