Google Research 发布中段物流实例生成器 MilleMiglia
原标题：MilleMiglia: A realistic instance generator for middle-mile logistics
AI 摘要
Google Research 发布开源 C++ 实例生成器 MilleMiglia，用于生成中段物流（middle-mile）网络的真实基准数据。该工具旨在填补学术界缺乏公开高质量物流数据的空白，因为物流公司通常将网络拓扑和需求数据视为敏感商业信息。MilleMiglia 将中段物流建模为时空图上的多商品流问题，捕捉货物在多个配送中心间换乘、按时间窗同步等复杂约束，代码和文档已在 GitHub 公开。
