The Vehicle Routing Problem with Soft Time Windows consists in computing a minimum cost set of routes for a fleet of vehicles of limited capacity that must visit a given set of customers with known demand, with the additional feature that each customer exp ...
In this thesis we consider some routing problems and exact algorithms to solve them based on the branch-and-price framework. We consider three variants of the Vehicle Routing Problem (VRP): the Capacitated Vehicle Routing Problem (CVRP): is the basic and m ...
The invention concerns a wireless data communication method, wherein a transmitter device (2) having a first broadband antenna (27) transmits ultra wideband coded data signals to a receiver device (3) having a second broadband antenna (37) for receiving th ...
The resource constrained elementary shortest path problem (RCESPP) arises as a pricing subproblem in branch-and-price algorithms for vehicle routing problems with additional constraints. We address the optimization of the RCESPP and we present and compare ...
Random textures differ from natural textures because they lack structure. Structure is a concept that is difficult to formalize, however, we generally observe that it is associated to spatial dependency between adjacent pixels. Random textures, in fact, ar ...
This study is making the case that the Universal Postal Service as currently defined at the European level should be modernized. The European Union plans to liberalize and build up an internal market for postal services by 2009 with the aim to foster impro ...
This paper proposes a framework to describe the influence of customer behaviour in the establishment of a satisfying business-to-business e-commerce strategy. A description of electronic sales channels typologies as well as of the attributes characterising ...

When vehicle routing problems with additional constraints, such as capacity or time windows, are solved via column generation and branch-and-price, it is common that the pricing subproblem requires the computation of a minimum cost constrained path on a gr ...
An automated surface mounting assembly procedure has been developed for mounting miniaturized optical elements. It is based on a low cost universal holding device, free space optical interconnection, and on-line adjustment of the elements. It is characteri ...
