Highlights An MIP model developed for current one-round food aid bidding system used by USDA. Humanitarian logistics challenges addressed via robust-optimization. Box and ellipsoid based frameworks employed to model uncertainty. USDA demand, supplier and carrier bid pricing uncertainties addressed. Case study utilizing historical invoice data demonstrates our model applicability.

    Abstract The U.S. Department of Agriculture (USDA) currently uses a bidding system to determine carriers and suppliers that would partner in providing food aid annually in response to global emergencies and famine. We mimic the USDA approach via a robust optimization model featuring box and ellipsoid uncertainty frameworks to account for uncertainties in demand, supplier and carrier bid prices. Through a case study utilizing historical invoice data, we demonstrate our model applicability in improving ocean carrier and food supplier bid pricing strategy and similar supply chain network optimization problems. Through a validation algorithm we demonstrate the value of our robust models.
