通过预测-聚类框架提升外卖配送实时调度效率
A Short-Term Predict-Then-Cluster Framework for Meal Delivery Services
- 先预测需求分布,再基于地理和约束条件动态聚类
- 在欧、台两地测试中准确率与效率均优于传统方法
- 适合需应对需求波动的即时配送与城市物流系统
微配送服务为按需城市物流提供有效方案,但其成功依赖高效的实时配送与车队管理。按需外卖平台需基于对全城需求分布的前瞻性洞察优化实时运营。本文提出一种短期预测-聚类框架,采用集成学习方法进行点值与分布预测,融合滞后输入以捕捉需求动态。引入约束型K均值聚类(CKMC)与迭代约束强化的连通性约束分层聚类(CCHC-ICE),根据预测需求与地理邻近性生成满足用户定义操作约束的动态聚类。欧洲与台湾案例研究显示,该方法在准确率与计算效率上均优于传统时间序列方法。聚类结果表明,引入分布预测能有效应对需求不确定性,提升运营洞察质量。仿真研究表明,短期需求预测可支持如闲置车队再平衡等主动策略,显著提升配送效率。该框架通过处理需求不确定性和操作约束,为实时运营优化提供可行动洞察,适用于其他按需平台化城市物流与出行服务,促进可持续高效的城市运行。
原文摘要 · Abstract (English)
Micro-delivery services offer promising solutions for on-demand city logistics, but their success relies on efficient real-time delivery operations and fleet management. On-demand meal delivery platforms seek to optimize real-time operations based on anticipatory insights into citywide demand distributions. To address these needs, this study proposes a short-term predict-then-cluster framework for on-demand meal delivery services. The framework utilizes ensemble-learning methods for point and distributional forecasting with multivariate features, including lagged-dependent inputs to capture demand dynamics. We introduce Constrained K-Means Clustering (CKMC) and Contiguity Constrained Hierarchical Clustering with Iterative Constraint Enforcement (CCHC-ICE) to generate dynamic clusters based on predicted demand and geographical proximity, tailored to user-defined operational constraints. Evaluations of European and Taiwanese case studies demonstrate that the proposed methods outperform traditional time series approaches in both accuracy and computational efficiency. Clustering results demonstrate that the incorporation of distributional predictions effectively addresses demand uncertainties, improving the quality of operational insights. Additionally, a simulation study demonstrates the practical value of short-term demand predictions for proactive strategies, such as idle fleet rebalancing, significantly enhancing delivery efficiency. By addressing demand uncertainties and operational constraints, our predict-then-cluster framework provides actionable insights for optimizing real-time operations. The approach is adaptable to other on-demand platform-based city logistics and passenger mobility services, promoting sustainable and efficient urban operations.
