Health Systems

Manager : Evren Sahin

Manager : Marija Jankovic

The S2S (Axe Systèmes de Santé) Healthcare System Group of LGI is interested in developing new approaches, methods and tools related to Industrial Engineering, that are relevant for care production systems. For certain problems encountered in Healthcare, Industrial Engineering approaches that were initially developed for manufacturing systems can be applied, by integrating some specific assumptions and adapting the models. Other types of problems necessarily involve the development of new research methodologies for the realistic modeling of healthcare systems. Models we develop aim at achieving patient objective quality of service (by reducing waiting times, process times, etc.) and satisfying caregivers preferences (consultation hours, equitable load distribution, etc.) while avoiding the waste of resources (practitioners time, operational costs, investment costs, etc).

In more details, topics covered in our research team are:

  • Modeling and simulation of hospital service operations
  • Modeling and simulation of operations in EMS (Emergency Medical Service) systems
  • Decision support for HomeCare
  • Decision support for the design of m-health technologies
  • Design of telemedicine systems

Energy System

Manager : Enrico Zio

Energy production and distribution systems, and loads.

The “energy systems” or “energy” axis brings together all research dealing with the technical and economic management of energy systems, including:

  • Economic viability, technical reliability, operational security, and the risks related to energy production, transmission, and distribution;
  • Comparative analysis of low-carbon electricity production technologies, such as renewables and nuclear resources, and the investigation of electricity storage solutions;
  • Integration of electrical mobility within the electricity supply and demand dynamics, investigation of new forms of low-carbon emission mobility solutions.
  • Energy efficiency (eco-parks, co-generation, transmission, distribution, etc.), demand side management (smart grids, curtailments, etc.), and the effect of consumers’ behavior and usages on the energy consumption within the lifecycle of the product.
  • Management of the different externalities produced by the energy system (beyond the CO2 emission), including nuclear wastes and the extraction of fossil and mineral resources.

Mobility System

Manager : Danielle Attias

Manager : Isabelle Nicolaï

New mobilities: what ecosystem for tomorrow?

Eco-mobility involves all mobility solutions and encompasses every type of transport – individual and shared, public and private – that contributes to providing a positive response to sustainable development issues. This eco-mobility is also smart and connected.

These new mobilities need to be analyzed with a multi-disciplinary approach, fitting into a context of prospective and disruptive innovation. Research approaches include engineering, economics and social sciences, and employ tools to design and model socio-technical mobility systems.

The models developed attempt to understand and satisfy stakeholders’ mobility requirements and identify the different action levers available to mobility suppliers while reducing the environmental and social impacts of the suggested solutions. In more detail, the themes tackled by our research are the following:

  • Sustainable urban mobility: The changing behavior patterns of mobility users call for new services. By analyzing what determines their mobility requirements, we can model user behaviors and define the most suitable products.
  • Electro-mobility economy: Prospective analysis highlights emerging business models, like electric vehicles integrated into the grid and autonomous, connected vehicles that, through their disruptive innovation model, create a new relationship between users and vehicles.
  • Disruptive innovation and the new “eco-mobility” system: New mobilities are analogous to disruptive innovations that challenge the entire value chain of the “eco-mobility” ecosystem. Technico-economic analysis allows us to identify the different action levers available to new players in terms of innovation and value creation.

Industry of Future an Connected Systems

Manager : Julie Le Cardinal

Manager : Bernard Yannou

Manager : Jean-Claude Bocquet

Within this axis, we are interested in both new production methods of hyper-connected factories of the future and, more generally, the design of connected systems.

In terms of the industry of the future, the aim is to develop new approaches and to transform production methods in industry and in a broader scope to master "performance 4.0" in companies.

The objective is to support companies in their transition from a traditional industry to the industry of future. This industry must be more respectful of the environment, thanks to less resource-consuming, more intelligent and flexible modes of production generating less waste, while rethinking the man-machine interface.
This research concerns digital transformations of the industrial model such as:

  • Transformation of business models by digital enterprises
  • Modernization of the production tool
  • More integrated design, marketing, supplier and sales functions
  • Switching from mass production of standard products to mass production of more personalized products

Moreover, we also consider in this axis the design of any connected system in the broad sense: connected systems of product type (example: health monitoring systems) as well as production systems as already evoked by "industry of future".

Industrial ecology

Manager : François Cluzel

Manager : Yann Leroy

Optimize material and energy flows in the design and manufacturing of goods and services

Circular Economy and Industrial Ecology are two complementary notions, where Industrial Ecology is seen as the scientific field allowing Circular Economy deployment thanks to strategies like eco-design of products and services, product-service systems, industrial synergies… The objective is to limit environmental impacts of human activities, for example by pooling material, water and energy flows in an integrated metabolism approach.

The four LGI teams are all particularly implicated on Industrial Ecology issues. Current research themes deal with:

  • Eco-design and eco-innovation methods and tools
  • Life Cycle Assessment (LCA) of products and services, technologies families, value chains…
  • Industrial symbioses and eco-industrial parks
  • Circularity indicators
  • Sustainable supply chain (reverse logistics, ecosystem services and sustainable supply chains…)
  • Energy efficiency
  • Technico-economic studies of industrial value chains including externalities
  • Decision making in complex environmental with great uncertainties

These research projects are applied in numerous industrial sectors, however sustainable buildings, cities and mobility are particularly targeted.
