Facing the issue of flash floods and their important damage both to victims infrastructures, involved authorities are interested in study ways answer at best this kind crisis long-term emergency phase. The victim relief operations can be optimized help rescue teams improve management situation. It is translated into field by development a decision support tool for operations. problem addressed ...

Precision farming in viticulture raises challenging combinatorial issues such as the Differential Harvest Problem . This problem might appear at first similar to a simple Capacitated Vehicle Routing but it exhibits problem-specific constraints that make this much harder solve and which are discussed article. Our objective was develop efficient exact methods using column generation VRPSolver™ ba...

Multi-echelon distribution systems are quite common in supply-chain and logistic systems. They are used by public administrations in their transportation and traffic planning strategies as well as by companies to model their distribution systems. In the literature, most of the studies address issues related to the movement of flows throughout the system from their origins to their final destina...

We study the Mixed Capacitated General Routing Problem (MCGRP) in which a fleet of capacitated vehicles has to serve a set of requests by traversing a mixed weighted graph. The requests may be located on nodes, edges, and arcs. The problem has theoretical interest because it is a generalization of the Capacitated Vehicle Routing Problem (CVRP), the Capacitated Arc Routing Problem (CARP), and th...
