DHL's routing suite cut bid costs by over $117M in 2.5 years
DHL built an integer-programming toolbox that prices and routes huge delivery bids, lifting its win rate and cutting costs.
DHL Supply Chain
那一手
DHL Supply Chain North America competes for contracts by promising to move customers' freight more cheaply than rivals. Its planners had to route fleets, decide what to outsource, and price bids, combinatorial problems involving up to nearly a million packages, done largely by hand.
With Ohio State University, DHL built TNO, a four-module integer-programming suite covering routing, outsourcing, pooling, and bid pricing. Analysts run all modules to build proposals, set fleet sizes, and position resources for existing customers.
Over 2.5 years since 2020, TNO produced over $117 million in estimated savings for DHL and its customers, contributed a 20% win-rate increase, and cut CO2 emissions by at least 0.1 megatons. Win rates on bids generated with TNO ran roughly 15% to 60%, with more than 20% generated after 2020.
为什么管用
- Routing and outsourcing are coupled; optimising them together beats local fixes.
- Accurate cost models mean DHL bids only on profitable work.
- Faster bid preparation lets analysts explore more scenarios.
- The tool captured expert logic, so winning bids became repeatable.
可以搬走什么
When every bid is a routing puzzle, the company that solves it fastest and cheapest wins more contracts. Optimisation tools turn a cost centre like bid preparation into a revenue engine.
后来呢
DHL was named a 2023 Franz Edelman Award finalist for TNO, with INFORMS citing savings of more than $98.6 million per year and $116.5 million in total past savings; the system remains in daily use for bidding and positioning.
