  System dynamic (SD) performance reflectsthe cost in a supply chain. This research investigates a three-echelonmanufacturing and remanufacturing closed-loop supply chain (CLSC) constitutingof a retailer, a manufacturer and a supplier. Each echelon, apart from itsusual operations in the forward SC (FSC), has its own reverse logistics (RL)operations. We assume that RL information is transparent to the FSC, and thesame replenishment policies are used throughout the supply chain. We focus onthe impact on dynamic performance of uncertainties in the return yield, RL leadtime and the product consumption lead time. Two outcomes are studied: orderrate and serviceable inventory. The results suggest that higher return yieldimproves dynamic performance in terms of overshoot and risk of stock-out with aunit step response as input. And, when the return yield reaches a certainlevel, the classic bullwhip propagation normally associated with the FSC doesnot always hold in CLSC. We also study bullwhip and inventory variance whendemand is a random variable. Our analysis suggests that higher return yieldcontributes to reduced bullwhip and inventory variance at the echelon level butfor the CLSC as a whole the level of bullwhip may decrease as well as increaseas it propagates along the supply chain.
