An Efficient Matheuristic for the Multicommodity Fixed-Charge Network Design Problem

Bernard Gendron, Said Hanafi, Raca Todosijević

In this paper we study the Multicommodity Fixed-Charge Network Design problem. We propose an Iterative linear programming-based heuristic for solving this NP hard problem. The proposed heuristics have been tested on the benchmark instances from the literature. The quality of solutions obtained by...

Unknown Input Observer for Understanding Sitting Control of Persons with Spine Cord Injury

Mathias Blandeau, Víctor Estrada Manzo, Thierry-Marie Guerra, Philippe Pudlo, François Gabrielli

The present paper introduces a simple model to study sitting control for persons with complete thoracic spine cord injury. The system is obtained via Lagrangian techniques; this procedure leads to a nonlinear descriptor form, which can be written as a Takagi-Sugeno model. A first attempt to...

Timetable Optimization to cope with Railway Infrastructure Maintenance

Luis Diego Arenas Pimentel, Paola Pellegrini, Joaquin Rodriguez, Said Hanafi

Maintenance Activities (MA's) are necessary to sustain the state and functionality of the railway infrastructure. However, MA's directly or indirectly affect the circulations of trains in the network, either by banning or by restraining them in some locations. Therefore, an efficient...

Aero-Thermal Optimization of a Heat Sink using Variable Neighbourhood Search

Pierre-Olivier Jandaud, Louis Lambourg, Souad Harmand

This paper presents a geometrical optimization of a heat sink modelled using three-dimensional CFD. The heat sink studied is circular with radial inlets and parallel fins. The parameters of the optimization are the different spacings between the fins. The optimization process is multi-objective and...

Takagi-Sugeno Model-based Steering Control for Autonomous Vehicles with Actuator Saturation

Tran Anh-Tu Nguyen, Chouki Sentouh, Jean-Christophe Popieul

This paper is devoted to the development of a novel control law for an autonomous vehicle. The control goal is to perform lane keeping under multiple constraints, namely actuator saturation of the steering system, roads with unknown curvature, and uncertain lateral wind force. Such system...

Integer programming based approaches for multi-trip location routing

Rita Macedo, Bruna Ramos, Cláudio Alves, José Manuel Valério de Carvalho, Said Hanafi, Nenad Mladenovic

The multi-trip location routing problem consists in selecting the depots to open and the routes that should be performed to serve a set of clients at minimum cost. The multi-trip variant considers the possibility for a vehicle to perform more than a single route during the planning period, and...
