Processus De Décision Et Complexité: Le Feu De Yarnell Hill Du 30 Juin 2013 [Decision-Making Processes And Complexity: The Yarnell Hill Fire Of June 30th, 2013], Karim Hardy, Louise K. Comfort Aug 2017

Processus De Décision Et Complexité: Le Feu De Yarnell Hill Du 30 Juin 2013 [Decision-Making Processes And Complexity: The Yarnell Hill Fire Of June 30th, 2013], Karim Hardy, Louise K. Comfort

Karim Hardy

Re-forming the information stream in decision processes after severe accidents allows scientists aRecréer les flux d’information au sein des processus de décision après une catastrophe permet aux chercheurs ainsi qu’aux décideurs d’identifier les points à partir desquels une action défaillante débute ainsi que les écarts dans les processus d’information qui pourraient être corrigés afin de réduire les futurs lors de futurs incidents. Le 30 juin 2013, le feu de Yarnell Hill en Arizona (Etats-Unis) évolue rapidement dans des conditions environnementale et managériale très difficiles menant à l’effondrement de la stratégie de lutte et à la ...


Hazard Mitigation Through A Systemic Model Of Accident To A Socio-Technical System: A Case Study, Karim Hardy, Franck Guarnieri Aug 2017

Hazard Mitigation Through A Systemic Model Of Accident To A Socio-Technical System: A Case Study, Karim Hardy, Franck Guarnieri

Karim Hardy

This paper presents the STAMP (systems-theoretic accident modeling and processes) accident model, based on systems theory, and describes its application in the context of risk prevention related to the remediation of contaminated sediments. The implementation of the model is described, and results are presented both in methodological and technical terms. The goal of this article is to emphasize the need of new approaches to take into account hazards and accidents within socio-technical systems.


Decisions Management During Wildland Fires: Accidents Viewed As A Spatiotemporal Inadequacy, Karim Hardy Aug 2017

Decisions Management During Wildland Fires: Accidents Viewed As A Spatiotemporal Inadequacy, Karim Hardy

Karim Hardy

Extreme situations as wildland fires are a source of stress and pressure. In such events, decision-makers and incident commanders need to address a specific problem: how to manage time and resources to make meaningful decisions? Current models of accidents that exist to explain and manage catastrophes and disasters are inadequate and insufficient to deal with resources and time pressure due to uncertainty within a complex organization. Current incident response structures are incompetent and impotent to handle effectively a dynamic evolution of space and time in order to bring a situation back to stability adequately.


Modelling And Hazard Analysis For Contaminated Sediments Using Stamp Model, Karim Hardy, Franck Guarnieri Aug 2017

Modelling And Hazard Analysis For Contaminated Sediments Using Stamp Model, Karim Hardy, Franck Guarnieri

Karim Hardy

Processes for remediation (removal of pollution or contaminants) of contaminated sediments have been very efficient. These technologies, which are particularly complex, call for a comprehensive approach to risk analysis which characterises all threats (to humans, equipment, local residents, the environment, etc.) . The STAMP accident model (Systems-Theoretic Accident Model and Processes) is an example of such a comprehensive approach, and it has been chosen to characterise the risks associated with Novosol (registered trademark), an innovative remediation process.


Modelling And Hazard Analysis For Contaminated Sediments Using Stamp Model And Stpa Tool, Karim Hardy, Franck Guarnieri Aug 2017

Modelling And Hazard Analysis For Contaminated Sediments Using Stamp Model And Stpa Tool, Karim Hardy, Franck Guarnieri

Karim Hardy

The goal of this article is dual: first, introducing a new model of accident named STAMP (systems-theoretic accident modeling and processes); then applying the model to an innovative process for the treatment of contaminated substances and the re-use of treated substances. This article is a demonstration for a need of a new tool to take into account hazards and safety within socio-technical systems.
