摘要：The crisis-management scenario in urban areas. El Eulma City Case-study (Algeria). The Civil Protection Services are increasingly challenged by crisis management, especially whenever located in areas that have significant spatial dysfunction, spawned by unplanned extensions around the industrial estates as is the case for El Eulma city. Owing to its sizable population and its proximity to hazardous installations, the city has become highly exposed to risks. Therefore, the objective of this work is to develop a decision-support tool in terms of relief management by pairing a PHAST simulation software with a GIS software (ArcGis). The approach is to create a georeferenced database under the MADS spatiotemporal representation, while integrating essential data in a geographical information system. With a view to efficient crisis management, the results reached by the study, have led to the spatialisation of the thermal effects of possible accidents, taking into account the location of all issues at stake. Network analysis has helped defining the shortest pathways for emergency services interventions.
