Walmart uses AI software to plan the most efficient routes for its delivery trucks, figure out how to pack trailers to minimize wasted space, and cut unnecessary miles from its logistics network. Walmart says this eliminated 30 million unnecessary miles and avoided 94 million pounds of CO₂ emissions. The company now sells this same routing technology to other businesses as a commercial software product.

Walmart developed its route optimization system internally over several years. It won the Franz Edelman Award, given by the Institute for Operations Research and Management Sciences to recognize impactful real-world applications of operations research. On March 14, 2024, Walmart Commerce Technologies commercialized the system as a software-as-a-service (SaaS) product called Route Optimization. For last-mile home deliveries, Walmart also runs an End-to-End Agentic Workflow — a multi-agent AI architecture where specialized digital agents continuously make micro-decisions about route assignment, driver availability, and order sequencing. A Dynamic Delivery Window System replaces fixed delivery time promises with real-time estimates updated to the minute as conditions change.
