Talk 1: Optimizing Supply Chain with Reinforcement Learning and Graph NNs
Abstract: Distribution networks are a crucial part of supply chains that often entail highly complex optimization problems. For example, optimizing the transportation cost of multiple kinds of goods over a time horizon with order consolidation requirements is an NP-hard problem. In this presentation, we will explore a distribution problem with such characteristics, called the Shipping Point Assignment (SPA) problem. Inspired by recent advances in combinatorial optimization using reinforcement learning and graph neural networks, we propose a deep Q learning agent with a GNN-based Value Function Approximation to optimize the SPA problem. We compare this agent with other RL-based and deterministic approaches in order to determine whether distribution networks of this kind could be better solved by ML-based techniques.
