Forecasting Dock Door Congestion in Warehouse Logistics: An Integrated Forecast–Optimization Framework—Extended Abstract

Dock door congestion is an essential and persistent concern within the realm of outbound warehouse logistics.The inability to accommodate outbound vehicles at the loading docks, especially during peak hours, disrupts internal warehouse operations, leads to bottlenecks, and contributes to substantial additional costs and delays.This paper addresses the critical issue of dock door congestion by proposing an integrated forecast-optimization framework for its prediction and management.The framework uses advanced forecasting methods and optimization techniques to increase warehouse throughput, boost operational efficiency, and predict potential congestion events using historical and real-time data.It combines two proven methodologies, maximum entropy bootstrap (MEB) and ensemble learning via bagging, with scenario-based stochastic optimization.This hybrid approach significantly improves upon traditional models by capturing the complex, non-monotonic components and multi-seasonality inherent in warehouse throughput data.Through a detailed realworld case study, we demonstrate how the proposed approach can accurately predict the number of trucks that can be serviced within specific time windows.This information is crucial for making operational decisions, such as whether to expand the warehouse.The approach can be generalized beyond the specific case study and offers valuable insights for any logistics or supply chain operation requiring the integration of stochastic optimization with predictive modeling.
