Data-Driven Predictive Framework
The research employed a meticulous methodology, starting with data cleaning and preprocessing of real-world Meituan delivery data. Key steps included: handling missing timestamp values, removing unaccepted orders, and enriching data dimensions through feature engineering (e.g., geographic block partitioning, predicted delivery speed, density levels, delay levels, peak hour indicators). To address significant class imbalance (5.78:1 ratio of on-time to late deliveries), a random undersampling strategy was implemented.
Seven models were evaluated: Logistic Regression, Decision Tree, Random Forest, Stacking, LightGBM, DNN, and 1D-CNN. Hyperparameter optimization was conducted using Random Search, with the F2 score as the primary evaluation metric, emphasizing Recall to minimize the cost of undetected delays.
Superior Performance with Stacking Ensemble
The study found that the Stacking ensemble model, following undersampling and hyperparameter optimization, significantly outperformed other individual models in terms of both predictive accuracy and robustness. Specifically, Stacking achieved a Test set F2 score of 0.4862 and a Recall rate of 0.7675, demonstrating its superior ability to correctly identify delayed deliveries compared to deep learning models like DNN and 1D-CNN, which showed strong generalization but slightly lower F2 scores on this tabular dataset.
Hyperparameter tuning notably improved Recall rates across all models (2% to 20% increase), emphasizing its role in managing complexity and enhancing generalization. Undersampling proved more effective than oversampling (SMOTE) for the Decision Tree, as synthetic samples could introduce noise and exacerbate overfitting for tree-based models on this specific dataset.
Unpacking Misclassification Patterns
Error analysis revealed distinct patterns. For samples with closer proximity between rider and merchant ('md_sender_recipient'), the Stacking model tended to produce False Negatives (missing actual delays), likely due to misjudging short delivery times as manageable. Conversely, for moderate to long distances, False Positives were more common, possibly because the model underestimated actual travel distances with parallel deliveries, solely relying on Manhattan distance. This highlights the need for more nuanced distance metrics.
Temporal analysis showed a higher proportion of False Positives during peak hours. This suggests the model was overly aggressive in predicting delays during busy periods, leading to resource wastage. Addressing this 'peak period aggressive' bias through weighted adjustments for sensitivity could further optimize the Stacking approach.

Case Study: Meituan's Enhanced Operational Efficiency
By integrating the predictive delay classification model, Meituan can empower its riders with intelligent decision-making support for order acceptance. Riders can assess tardiness risk in real-time, reducing personal penalties and improving job satisfaction. Furthermore, the platform gains enhanced capabilities to proactively manage delivery expectations, notify customers of potential delays, and optimize resource allocation.
This directly translates into improved user satisfaction, reduced customer service load, and more efficient resource utilization across the delivery network. The model's ability to differentiate between "fast", "normal", and "slow" regions allows for dynamic adjustments in estimated arrival times, fostering greater transparency and reliability in food delivery services.
