Reflection on a model of accident reporting to help to implement efficient prevention strategies

International audienceIn our modern societies, socio-technological systems and human system interactions are taking on a large part in numerous domains such as health, control of risk, people safety, communication, information technologies, and so on. In order to manage such systems, it is necessary to put in place the most relevant actions and indicators. To facilitate decision making in various fields, such as people safety and risk management, the use of appropriate model and the definition of indicators are needed in order to deliver the relevant action plan especially to control occupational accidents. The aim of the article is to present our approach to analyze the classical Heinrich's model of occupational accidents and the classical safety indicator based on conventional frequency rate of lost time accident. Then we demonstrate their limits in order to define efficient prevention strategies

How to define and use safety indicators to implement an efficient prevention policy

International audienceIn our modern societies, socio-technological systems and human system interactions are taking on a large part in numerous domains such as health, control of risk, people safety, communication, information technologies, and so on. In order to manage such systems, it is necessary to put in place the most relevant indicators. To facilitate decision making in various fields such as people safety and risk management, the definition of indicators generated by such systems is needed in order to deliver the appropriate action plan especially to control occupational accidents. The aim of the article is to present our approach to analyze and define this category of new indicators

Using Indicators for System Complex Safety

International audienceIn our modern societies, technological systems are taking on a large part in numerous domains such as automatic control, calculation, communication, information technologies, etc. They are put in place in more and more fields e.g. production, defense, national security, space, etc. These very important developments are offering new possibilities such as distributed cooperative and concurrent decision making based on complex dynamic systems or on advanced simulation capacities. To facilitate decision making in various fields such as transport, energy or even risk management, it is necessary to define indicators generated by such systems in order to deliver engineers or managers an image of the considered object and it's evolution. This image must be coherent, reliable and sustainable in order to participate at the decision in a complex sociotechnical environment. The aim of the article is to present our approach to define this category of new indicators

The Contribution Of Radio Sciences to Disaster Management

Available: http://www.isprs.org/proceedings/2011/Gi4DM/CDDATA/sessions.htmlInternational audienceWhen a natural disaster occurs, the fast and effective organization of emergency assistance assumes the rapid provision of reliable information concerning the state of the infrastructure; the creation, in almost real-time, of a response chain and the reconfiguration of telecommunications systems. This article proposes a chain which incorporates algorithms from recent research, with particular focus on communication systems and reconfiguration techniques. The problems of image reliability and the effects created by ionospheric propagation and turbulent surfaces are discussed
