• MAIN RESEARCH INTERESTS
  • Current :

Currently I am researcher in the team Integrated horticultural crop production. My research focus is on the model-based design of integrated horticultural production systems. The developed approaches are mainly originated from artificial intelligence and multicriteria decision making. They aim to formulate the design of integrated horticultural production systems as a multiobjective optimization problem and to propose efficient algorithms able to resolve this kind of optimization problems. This work uses the biotechnical models developed by my colleagues. These models describe either the interactions between plants, pests, and natural enemies under the effect of cultural practices or the interactions between genotypes, environments and cultural practices. Our short-term objective is to be able to propose effective and realizable technical procedures that satisfy many antagonist criteria and respect some biotic and abiotic constraints.

• • Past :

*Postdoc

During my postdoctoral stay at Université du Littoral Côte d’Opale and GDF, I had worked on the optimal design and dimensioning of hydrogen transmission distribution pipeline networks. The design problem includes the topology determination and the dimensioning problem. We developed new solution method that simultaneously looks for the least cost topology of the network and for the optimal diameter of each pipe. These two problems were generally solved separately in the literature. The proposed approach was applied to the case of development of future hydrogen pipeline networks on several urban areas in Europe and the obtained results demonstrated the effectiveness of this approach compared to the classical ones. The networks were modeled by means of graphs and the proposed approach was based on the nonlinear optimization techniques. This work was realized with the collaboration of Gaz de France, Total, and The French petrol institute (IFP) in the framework of the EcoTransHy project.

*PhD Thesis

In my PhD thesis I had interested to the real-time regulation of the urban collective transportation networks. This is a very difficult problem, especially in case of appearance of simultaneous disturbances (vehicle’s breakdown, strike, and demonstration). Regulator (decision-maker) has to carry out difficult tasks that are often inaccessible at the human scale and involve the assistance of a decision support system (DSS). We developed the main part of this DSS that is generator and evaluator of the decision strategies for a disrupted transport network regulation. The proposed module is based on a hybrid approach using a fuzzy evaluation method and evolutionary algorithms. It treated the regulation problem as an optimization one and provides the regulator with evaluated and classified effective decisions by taking into account his/her preferences. This work was realized in collaboration with INRETS (French National Institute for Transport and Safety Research), Ecole Centrale de Lille, Lille University for Sciences and technologies, and Valenciennes University.

Keywords: Integrated production systems, modeling, decision-making, optimization by simulation, multiobjective optimization, evolutionary algorithms, fuzzy logic.
