Data-Driven Modelling and Optimization in Warehousing: The Order Consolidation and the Pallet Loading Problems

Samir Eldhedhli - University of Waterloo

With the considerable growth in e-commerce and retailing, warehouses are playing a central role in supply chain efficiency. Motivated by an industrial project with a global logistics company and based on real data, we study two practical, yet challenging, problems in warehousing. First, we study the order fulfillment problem in an e-warehouse. Based solely on data, we analyze the picking, order fulfillment, and order consolidation operations. We then introduce and solve the Order Consolidation Problem, a new problem in warehouse operations and parallel machine scheduling. Second, we focus on the Pallet Loading Problem in retail distribution, a generalization of three-dimensional bin packing to include practical constraints such as item support, pallet stability, and load bearing. We propose a new layer-based formulation and an efficient column generation solution approach. We present detailed analysis and comparisons and offer directions for future research.
