Application of a Co-evolutionary Genetic Algorithm to solve the Periodic Railway Timetabling Problem

Luis Diego Arenas Pimentel, Rémy Chevrier, Said Hanafi, Joaquin Rodriguez

In train operations, a timetable is used to establish the departure and arrival times for the trains at the stations or other relevant locations in the rail network. The timetable must respond to the commercial requirements of the customers, while respecting also some security and capacity…

Tutoriel : Variable neighbourhood and Formulation space searches: some recent advances

Nenad Mladenovic

<p>Variable neighbourhood search (VNS) and Formulation space search (FSS) are two general search strategies for solving optimization problems that follow the principle of change during the search for the better solution. In VNS, the neighbourhood structures are systematically changed, while…

On the complexity of robotic flow shop with transportation constraints

Nacira Chikhi, Moncef Abbas, Abdelghani Bekrar, Rachid Benmansour, Said Hanafi

Most of machine scheduling models in the literature assume that either transportation capacity of transporters for delivering jobs is unlimited or transportation times from one location to another are negligible. In this paper, we study a two stages robotic flow shop problem which is a scheduling…

A hybrid approach combining column generation and variable neighborhood search for the location and routing problem

Rita Macedo, Said Hanafi, Bassem Jarboui, Nenad Mladenovic, Bruna Ramos, Cláudio Alves, J.M. Valério de Carvalho

<p>The location and routing problem is an integrated problem, combining two problems of the supply chain, the location problem and the vehicle routing problem. The combination of these two important optimization problems to distribution networks can translate into considerable savings, given…

Decision Support System for Offers of Fleet Availability Services

André Pozzetti, Ioana Bilegan, David Duvivier, Abdelhakim Artiba, Sébastien Forato, Barbara Matrat, Sébastien D’arco

The growing competitiveness within the aeronautic industry is inspiring companies to implement and offer Performance-Based Services. Whilst not necessarily a new concept, it is relatively new to the commercial aeronautic industry and presents prime suppliers with difficulties in predicting…

Optimization of multimedia applications on embedded multicore processors, Optimisation des applications multimédia sur des processeurs multicœurs embarqués

Elias Michel Baaklini

Parallel computing is currently the dominating architecture in embedded systems. Concurrency improves the performance of the system rather without increasing the clock speed which affects the power consumption of the system. However, concurrency needs to be exploited in order to improve the system…, L’utilisation de plusieurs cœurs pour l’exécution des applications mobiles sera l’approche dominante dans les systèmes embarqués pour les prochaines années. Cette approche permet en générale d’augmenter les performances du système sans augmenter la vitesse de l’horloge. Grâce à cela, la…

Liquid film evaporation enhancement in a vertical annulus with preheated air flow

Rym Ben Radhia, Souad Harmand, Jean-Pierre Corriou, Sadok Ben Jabrallah

The evaporation by mixed convection of a water film falling down the inner wall of a vertical annulus was studied numerically. The outer wall was assumed to be insulated and dry. A counter-current flow of preheated, dry air was blown between two concentric cylinders. This air flow was preheated at…

Experimental investigation on the feasibility of heat pipe cooling for HEV/EV lithium-ion battery

Thanh-Ha Tran, Souad Harmand, Bernard Desmet, Sebastien Filangi

In this paper, the use of flat heat pipe as an effective and low-energy device to mitigate the temperature of a battery module designed for a HEV application was investigated. For this purpose, nominal heat flux generated by a battery module was reproduced and applied to a flat heat pipe cooling…

On the implementation of a nonlinear shell-based SPH method for thin multilayered structures

Jun Lin, Hakim Naceur, Abdel Laksimi, Daniel Coutellier

An efficient Smoothed Particle Hydrodynamics method is developed in this paper for bending and buckling analysis of laminated composite plates and shells. The governing differential equations of thin structures is based on the First-order Shear Deformation Theory considering the geometrically…

Airport Security Microwave Scanner, SAMOSA -ScAnner Micro-Onde pour la Sécurisation des Aéroports Airport Security Microwave Scanner

Gwenn Le Fur, Luc Duchesne, Virginie Tessier, Juan-Carlos Castelli, Antoine Osmont, Igor Crevits, Bako Rajaonah, Joss Berger, Pierre Cabrol, Vivien Braida

Recent events have shown that a determined terrorist could be able to board in a plane with explosive materials to blow up the plane during the flight. The risk that a kamikaze perpetrates a terrorist attack in the cabin of a plane is undeniably real. SAMOSA project falls within this context. Its…, – Des événements récents ont montré qu'un terroriste déterminé était encore capable d'introduire à bord d'un avion de ligne des matières explosives pour tenter de le faire exploser en vol. Le risque d'attentat à l'explosif perpétré par un passager kamikaze dans la cabine d…
