The transportation problem is a fundamental problem in Operations Research, where items need to be transported from supply nodes (each with a given supply) to demand nodes (each with a given demand) in the cheapest possible way. Here, we are interested in a generalization of the transportation...

We study optimal transport networks in spatial equilibrium. We develop a framework consisting of a neoclassical trade model with labor mobility in which locations are arranged on a graph. Goods must be shipped through linked locations, and transport costs depend on congestion and on the...

This paper presents a Genetic Algorithm for the Vehicle Routing and Scheduling Problem with time windows and temporal synchronization constraints. That means that as opposed to the usual procedure, in addition to the usual task covering, some vertices must be served by more than one vehicle at...
