Researchers have developed an OR-guided Large Language Model for Allocation (ORLA) designed to tackle complex multi-warehouse inventory allocation problems in e-commerce supply chains. This model integrates automatic generation of problem-model-code (PMC), learning-based formulation selection, and feasibility restoration, using solver feedback to verify and refine operations research (OR) formulations. ORLA demonstrated significant improvements, with its best single formulation enhancing allocation accuracy by 3.4 percentage points and the full framework achieving a 4.5 percentage-point overall improvement across 29 production evaluation batches.
