Laboratoire Génie Industriel- LGI - Industrial Engineering Department
The goal of the Industrial Engineering (IE) Department (Laboratoire Genie Industriel, LGI) is to develop models, methods and tools for diagnosing, specifying, designing, developing, manufacturing, launching, exploiting, recycling at best socio-technical systems. These systems are industrial systems (production systems, value chains, eco-parks), complex products (airplanes, cars…), complex factories, transportation systems, health systems, energy networks, service systems and construction systems. Key principles of our research are: multidisciplinarity, life-cycle thinking, societal issues, model-based engineering approaches.
Studied systems are often characterized by the following:
- the presence of sophisticated technical components but also of human agents (organizations, policy makers, operators)
- a large number of individual components that interact,
- heterogeneity of these components, each with specific individual behavior,
- systems that must often be analyzed at different physical, spatial and temporal scales and from different points of view (technical performance, cost, environmental impacts, material flows, skills...
- a system feedback on its components and the emergence of macroscopic properties.
The control of such systems presents many challenges and issues from both a technical and scientific point of view as well as practical and application perspectives like financial profitability, efficiency, continuity and reliability of service, security. The integration of technical systems is already challenging regarding, for example, aerospace, automotive or energy systems, but it is even more complex when it comes to inter- network systems («System of Systems» paradigm) such as health systems, human mobility infrastructure, distribution of products and services, transport and regulation of energy, gas, water, and other socio- technical systems including human or various agents such as organizations with different and even contradictory strategies, goals and preferences. Our scientific approach consists in adequately modeling for analyzing and simulating in order to better understand the system behavior through virtual experiments on models and, ultimately, finding optimal solutions for the design, deployment and monitoring. Often many life cycle phases of these systems must be modeled and
analyzed: collection of needs and requirements specification, development
(architectural design, design, validation, manufacture and market launch or startup), system management (its regulation, its maintenance, its failure modes, its upgrade), its dismantling and end of life.
The 4 research Groups of the IE department and their research topics
Ten industrial chairs and two research institutes reinforce the 4 research groups.
The 10 industrial chairs are about: Sustainable Construction (Bouygues Construction), Operational Excellence (BNP Paribas), Production and Logistic (Faurecia), Supply Chain (LVMH, Sanofi, Carrefour, Safran), Electro-mobility (PSA Peugeot Citroën), Energy Economy (Capitaldon), Systems Engineering (Safran), Purchasing in complex projects (Total), Systems Sciences (EDF), Anthropolis (Alstom transports, Engie, IRT SystemX, RATP, Renault, SNCF).
