ORBi Open Repository and Bibliography (303.388 recursos)

In may 2007, the ULg's Administrative Board (joined in June 2007 by the FUSAGx) decided to create an institutional repository and defined a strong institutional self-archiving policy to increase the visibility, accessibility and impact of the University's publications (Board's decision). This decision led to the official launch, in November 2008, of the ORBi platform including both the Academic Bibliography and the Institutional Repository of the Wallonia-Europe University Academy.

  7. NANO-STORE RETAILERS’ DISTRIBUTION SYSTEM MANAGEMENT IN EMERGING COUNTRIES

    Sabiri, Asmaa; Riane, Fouad; Limbourg, Sabine
    Emerging megacities are still abounded with traditional distribution channels. These retail formats need to be visited and supplied very frequently, which turns to be costly and time consuming. In this paper, we address an optimization problem for supplying nanostores (or high frequency stores), while combining districting problem and an altered traveling salesman problem. We present a reallife case study where a company tries to build an effective strategy to cover and supply its nanostores’ network. The problem of concern is modeled as an assignment problem, combined with side constraints regarding disruption of pre-assignments and profit potential balance. The results show...

  15. The three-dimensional rectangular Multiple Bin Size Bin Packing Problem with transportation constraints: A case study in the field of air transportation

    Paquay, Célia
    According to the International Air Transport Association and Air Transport Action Group, 51.3 million metric tons of goods were transported by airlines in 2014. To transport luggage, freight and mail, special containers, called Unit Load Devices (ULD), are used. The method of loading packages into ULDs represents a key element for cargo safety and aircraft weight and balance, as well as for the economy of airline companies. This thesis aims to solve the problem of packing a set of boxes into containers of various shapes without wasting loading space. The goal is to select the best set of ULDs to pack all the boxes achieving a minimum unused volume....

  20. A constructive heuristic for the three dimensional Bin Packing Problem with transportation constraints

    Paquay, Célia; Schyns, Michael; Limbourg, Sabine
    The aim of this work is to propose a Relax-And-Fix heuristic to build a good initial solution to the 3D BPP. First, a mathematical formulation has been developed taking into account several types of constraints such as the stability and fragility of the boxes to pack, their possibility to rotate, the weight distribution inside the bins and their special shapes. Since this model contains a lot of integer variables, we have decided to apply the Relax-and-Fix method. We have selected several sets of variables to be the branching variables and carried out some tests.
