Modelling and management of the strain situations in hospital systems using an ORCA approach

Farid Kadri, Cyrille Pach, Sondès Chaabane, Thierry Berger, Damien Trentesaux, Christian Tahon, Yves Sallez

Management of patient flow, especially the flow resulting from health crises (exceptional situations) in emergency departments (ED), is one of the most important problems ED managers have to deal with. Emergency departments require significant human and material resources to handle this influx of...

A new Hybrid Heuristic for the 0-1 Knapsack Sharing Problem

Boukthir Haddar, Mahdi Khemakhem, Said Hanafi, Christophe Wilbaut, Habib Chabchoub

In this paper we consider the 0-1 knapsack sharing problem, which is a max-min optimization problem with a knapsack constraint. This problem has a wide range of commercial applications and occurs when resources have to be shared or distributed fairly to several entities. We propose a new hybrid...

A general variable neighborhood search for the travelling salesman problem with draft limits

Raca Todosijević, Anis Mjirda, Said Hanafi, Nenad Mladenovic, Bernard Gendron

In this paper, we present two General Variable Neighborhood Search for the Traveling Salesman Problem with Draft Limits (TSPDL), a recent variant of the Traveling Salesman Problem. TSPDL arises in the context of maritime transportation. It consists of finding optimal Hamiltonian tour for a given...

Multi-user interferences in ultra wide band system based on Modified Gegenbauer functions and M-OAM modulation

Khadija Hamidoun, Raja Elassali, Yassin El Hillali, Khalid Elbaamrani, Atika Rivenq, Fouzia Boukour

This paper studies the effect of multi-user interferences in the Impulse radio ultra-wideband (IR-UWB) system based on the Orthogonal Amplitude Modulation (M-OAM). Indeed in previous work, we proposed to use original modulation schemes called Orthogonal Amplitude Modulation (M-OAM) in order to...

Variable neighborhood search for the location routing problem with multiple routes

Rita Macedo, Said Hanafi, Bassem Jarboui, Nenad Mladenovic, Claudio Alves, José Manuel Valério de Carvalho

We address a variant of the Location Routing Problem (LRP) where vehicles can perform several routes in the same planning period and both depots and vehicles have capacities. This problem represents a combination of two NP-hard problems: a vehicle routing problem, which determines the optimal set...

Decision Support System for auditing logistics information systems

Maroi Agrebi, Mounir Benaissa, Mourad Abed

In this paper, we propose a methodology for auditing logistics information systems, especially the audit of distribution logistics information systems. The proposed approach is based on a multi-criteria hierarchical ranking and is built around a decision support system called SADAUDIT that allows...

A joint maintenance and production strategy to minimize the makespan

Houda Elhadaf, Mohamed Tkiouat, Rachid Benmansour, Abdelhakim Artiba

In this paper, we study the problem of scheduling n jobs without preemption on a machine subject to random failures. To illustrate the performance of the proposed strategy, we consider the production sequence as non-fixed. The machine undergoes minimal repair whenever it fails. To minimize the...

Hybrid genetic algorithm for bi-objective assignment problem

Mustapha Ratli, Mansour Eddaly, Bassem Jarboui, Sylvain Lecomte, Said Hanafi

We propose a hybrid approach for multi-objective assignment problem which combines genetic algorithm and mathematical programming techniques. This method is based on the dominance cost variant of the multi-objective genetic algorithm hybridized with exact method. The initial population is generated...

Regularity results for elliptic problems with measure

Sadjiya Ariche, Colette De Coster, Serge Nicaise

In this work, we study the solution of the Laplace equation: \[ -\Delta u =g \delta_\sigma\;\;\;\hbox{ in } Q\subseteq \mathbb{R}^3, \] where \(\delta_\sigma\) is the Dirac mass on a crack \(\sigma\) of \(Q\) and \(g\in L^2(\sigma)\). First, we discuss the existence and the uniqueness of a solution...
