The multicommodity network flow problem is a classical issue in network optimization, where the objective is to route multiple commodities through interconnected nodes and arcs to minimize the overall flow cost. However, in practical scenarios, parameters such as arc capacities, node demands,...

The multi-commodity network flow problem (MCNF) consists in routing a set of commodities through a capacitated network at minimum cost and is relevant for routing containers in liner shipping networks. As commodity transit times are often a critical factor, the literature has introduced hard...

En un sistema formado por una red de nodos emisores y receptores de información, es necesario conocer el estado de señal que tendría cada uno de esos nodos en todo momento con el fin de lograr un flujo de información adecuado. El objetivo de este trabajo es obtener un modelo matemático que...
