International Materials, LLC (IMI) operates a network of Contracts of Affreightment (COAs) that govern how bulk cargo is shipped from Spanish origins — Almeria and Garrucha — to 18 discharge ports across the East Coast of North America.
Each COA carries contractual obligations: minimum and maximum shipment counts that must be honored per planning period. At the same time, every destination port has a minimum demand that must be met.
The competition objective is to determine the optimal number of shipments per lane per destination — minimizing total freight cost while satisfying all contractual and demand constraints using Integer Linear Programming.
