Study of mixed integer programming models for the concrete delivery problem by Hernández López, Óscar Alejandro

“…Contributions and Conclusions: The main contribution of this thesis is two new compact MIP models. These formulations, based on a graph representation, reduce the number of used variables and restrictions involved in the problem and allow us to solve to optimality more instances than the mathematical models that have been presented in the literature for this problem…”
