Modélisation basée sur une ontologie pour la simulation de comportements de nouveaux-nés lors de la réanimation cardio-pulmonaire
International audienceThis chapter concerns the formulation of a methodology and its implementation to elaborate a training simulator for medical staff who may be confronted with the critical situations of new-borns resuscitation. The simulator reproduces the different cardio-pulmonary pathological behaviours of new-borns, the working environment of resuscitation rooms, and the monitoring and control environment of the learners by a teacher. Conceptual models of new-borns behaviours combined with the cardio-pulmonary resuscitation gestures have been developed. The methodological process is jointly using cognitive approaches with formal modelling and simulation. Cognitive approaches are mobilized to elaborate application ontologies to be the bases for the development of the conceptual models and the specification of the simulator. Ontologies have been developed on the bases of a corpus of academic documents, return on experience documents, and practitioner interviews, by means of the Knowledge Oriented Design (KOD) method. A discrete event formalism has been used to formalize the conceptual models of the new-borns behaviours. As a result, a simulator has been built to train medical practitioners to face situations, which are reported to potentially cause errors and thus improve the safety of the resuscitation gestures
Ontology-Based Modeling for Newborn Behavior Simulation during Cardiopulmonary Resuscitation
This chapter concerns the formulation of a methodology and its implementation to elaborate a training simulator for medical staff who may be confronted with the critical situations of newborn resuscitation.

Ătude de la VulnĂ©rabilitĂ© des ChaĂźnes Logistiques FondĂ©e sur l'IngĂ©nierie Cognitive et les ModĂšles Formels ARIMA
International audienceThis research concerns the formulation of models and methods for supply chains risk analysis. An ontological approach using the KOD method (Knowledge Oriented Design) has been implemented to clearly identify relationships between the concepts of supply chain, risk, vulnerability and disturbances (critical scenarios). As a result, conceptual models of supply chains facing risk situations and critical scenarios are proposed. From the resulting conceptual models and mathematical models proposed in the literature, a multi-stage supply chain model using ARIMA models incorporating the randomness of the demand has been elaborated. In order to adapt this model to scenario criticality, constraints on orders and inventories have been taken into account. Under critical disturbances on information flows (demand) and physical flows (quality of the product supplied), constraints can be reached and supply chain behaviours can evolve toward critical dynamics or even become unstable. Supply chain vulnerabilities has been assessed and discussed

Orléans : étude relative à la protection de la zone centre en bordure des quais
Ce rapport dâactivitĂ© concerne « lâĂtude Relative Ă la Protection de la Zone Centre dâOrlĂ©ans situĂ©e en bordure des quais». Il constitue le dernier livrable dâun projet de recherche contractuel Ă©tabli entre la sociĂ©tĂ© Altoo, Aix-ÂâMarseille UniversitĂ© (AMU) et le Centre National de la Recherche Scientifique (CNRS). Le Plan Loire Grandeur Nature est lâorganisme financeur de ce projet. Lâobjet de ce projet de recherche consistait Ă Ă©tablir une mĂ©thode gĂ©nĂ©rique (la mĂ©thode Indigoo) dâĂ©valuation des impacts dâune inondation sur un territoire, en terme de dommages monĂ©taires, et des apports de mesures de protection, en terme de bĂ©nĂ©fices ou dâĂ©conomies monĂ©taires. LâĂ©tude qui fait lâobjet de ce rapport est destinĂ©e Ă tester et valider la mĂ©thode Indigoo. Une Ă©tude similaire a Ă©tĂ© rĂ©alisĂ©e sur le territoire de la ville de Tarascon. Ce travail a Ă©tĂ© menĂ© de façon conjointe Ă une Ă©tude technique qui a permis de caractĂ©riser expĂ©rimentalement les performances du systĂšme Altoo en prĂ©sence de contraintes hydrodynamiques. Les modĂšles expĂ©rimentaux issus de cette Ă©tude ont servis de base Ă la construction dâun simulateur de scĂ©narii dâinondation. Les rĂ©sultats de ces simulations sont intĂ©grĂ©s Ă Indigoo en vue dâĂ©valuer lâapport du systĂšme Altoo
