A branch-and-price algorithm for the robust single-source capacitated facility location problem under demand uncertainty

Ryu, Jaehyeon; Park, Sungsoo - In: EURO journal on transportation and logistics 11 (2022), pp. 1-12

We consider the robust single-source capacitated facility location problem with uncertainty in customer demands. A cardinality-constrained uncertainty set is assumed for the robust problem. To solve it efficiently, we propose an allocation-based formulation derived by Dantzig-Wolfe decomposition...
