USPS uses transportation modeling to reduce transportation costs
ILOG announced that the United States Postal Service (USPS) has realized over USD 5 million in annual savings through a strategic transportation management initiative. Developed by USPS and IBM using ILOG CPLEX(R) optimization software, the Highway Corridor Analytic Program (HCAP) uses advanced technology to analyze USPS highway transportation scenarios and identify cost saving opportunities. The HCAP model examines routing and scheduling options to minimize costs while meeting business goals – leading to a savings of over USD 10 million in the two years since the model was deployed in 2006.
The USPS transportation network is large and complex – including responsibility for shipping over 200 billion pieces of mail per year through a system of transportation networks – and accommodates many different levels of services to its customers.

These complexities of various mail sizes, weights, and classes, coupled with the large scale of the USPS network, create a challenging environment in which to plan and manage transportation.
