Abstract:

System dynamic (SD) performance reflects the cost in a supplychain. This research investigates a three-echelon manufacturing andremanufacturing closed-loop supply chain (CLSC) constituting of a retailer, amanufacturer and a supplier. Each echelon, apart from its usual operations inthe forward SC (FSC), has its own reverse logistics (RL) operations. We assumethat RL information is transparent to the FSC, and the same replenishmentpolicies are used throughout the supply chain. We focus on the impact on dynamicperformance of uncertainties in the return yield, RL lead time and the productconsumption lead time. Two outcomes are studied: order rate and serviceableinventory. The results suggest that higher return yield improves dynamicperformance in terms of overshoot and risk of stock-out with a unit stepresponse as input. And, when the return yield reaches a certain level, theclassic bullwhip propagation normally associated with the FSC does not alwayshold in CLSC. We also study bullwhip and inventory variance when demand is arandom variable. Our analysis suggests that higher return yield contributes toreduced bullwhip and inventory variance at the echelon level but for the CLSCas a whole the level of bullwhip may decrease as well as increase as it propagatesalong the supply chain.
