Abstract
Managing replenishment and fulfillment across multiple sales channels requires carefully balancing inventory flow to minimize stockouts and overstocks. Replenishment involves determining order quantity in cycles, while fulfillment focuses on meeting uncertain demand across channels with limited capacity, both posing significant challenges. We address this problem in large-scale networks and propose a decomposition-based Deep Reinforcement Learning (DRL) algorithm. Our framework enhances demand management, scalabilty, and, and efficiency, ensuring robust performance under varying demand conditions.
