📝 摘要(中文)
应急管理援助项目,如救援物资分发,对于向受影响社区提供必要的供应至关重要。然而,这些项目在面对不确定的地方需求和供应动态时,往往在地方中心的网络中独立运作,导致服务的不一致性。为此,本文提出了CoRe-MARL,一个基于递归多智能体强化学习的合作框架,通过将每个中心视为一个智能体,学习再分配策略,以改善服务并缩小服务差距。该框架利用递归网络捕捉动态变化的供需关系,并通过多智能体近端策略优化(MAPPO)实现集中训练和分散执行。实验结果表明,CoRe-MARL在不同轨迹下表现出色,能够有效提升服务质量,尤其是在服务最差的中心。

📄 摘要(原文)
Emergency management assistance programs, such as relief distribution, are essential for delivering necessary supplies to affected communities. However, these programs operate in a decentralized network of local centers that face uncertain local demand and supply dynamics, resulting in inconsistent avail- ability of local services. Redistribution of supplies among these local centers reduces these imbalances, but the centers often make decisions independently, with limited information and disrupted transportation. This study develops CoRe-MARL, a cooperative multi-agent reinforcement learning (MARL) framework, by formulating a decentralized partially observable Markov decision process (Dec-POMDP). We treat each center as an agent that learns a redistribution policy to improve the service in the worst-case region and reduce the service gap across regions while protecting network-wide service. We incorporate a recurrent network that captures evolving supply and demand dynamics without direct observation, while multi-agent proximal policy optimization (MAPPO) enables centralized training and decentralized execution (CTDE). We evaluate the framework in a simulated environment with diverse trajectories, where exact dynamics are not observed by actors and the MAPPO critic. We compare the recurrent MAPPO with the recurrent independent PPO (IPPO) and a local only heuristic, and find that MAPPO reduces the service gap across local centers and enhances service for the worst-served center while maintaining competitive network-wide service. The recurrent MAPPO also shows consistent performance across diverse trajectory patterns, demonstrating its ability to adapt to evolving dynamics. The findings demonstrate the capability of cooperative learning for decentralized redistribution and improving equitable service under uncertain and evolving dynamics.
