Stronger multi-commodity flow formulations of the Capacitated Vehicle Routing Problem

Letchford, Adam N.; Salazar-González, Juan-José - In: European Journal of Operational Research 244 (2015) 3, pp. 730-738

The Capacitated Vehicle Routing Problem is a much-studied (and strongly NP-hard) combinatorial optimization problem, for which many integer programming formulations have been proposed. We present two new multi-commodity flow (MCF) formulations, and show that they dominate all of the existing...
