Two seconds later, the answer bloomed: Objective Function Value = $47,281.00 .

She ran the module to route beans from three ports to five roasting plants. She ran Inventory to find the optimal reorder point. The software never complained, never froze. It was like having a stoic, chain-smoking operations researcher from 1972 living inside her computer.
