Brief communication "An auto-diagnosis tool to highlight interdependencies between urban technical networks"

Abstract

Abstract. Natural hazards threaten the urban system and its components that are likely to fail. With their high degree of interdependency, urban networks and services are critical issues for the resilience of a city. And yet, network managers are scarcely aware of their flaws and dependencies and they are reluctant to take them into account. In order to develop an operational tool to improve urban resilience, we propose here an auto-diagnosis method to be completed by network managers. The subsequent confrontation of all diagnoses is the basis of collaborative research for problem identification and solution design. The tool is experimented with the Parisian urban transport society.

Preface "Natural hazard resilient cities"

“…This Special Issue "Natural-hazard-resilient cities" contains eight articles. Amongst these articles, one of them is a short communication (Toubin et al, 2012). The teams that have contributed to this number come from different types of laboratories.…”

“…heat waves) (Tromeur et al, 2012). However, above all, it is the predominance of flood hazards that is discussed in six articles (Mebarki et al, 2012;Gersonius et al, 2012;Toubin et al, 2012;Beraud et al, 2012;Lhomme et al, 2013;Eleutério et al, 2013). Lastly a multi-hazard approach has been developed in the article by Djalante (2012).…”

“…On account of its size, its topicality and its social and economic cost, flood hazard has been named as the critical issue at stake in most of the territories studied in this special number. This approach via flooding could have been replaced by other types of hazard, or even by multi-hazard approaches (Gersonius et al, 2012;Toubin et al, 2012;Béraud et al, 2012;Lhomme et al, 2013;Euletério et al, 2013).…”

Developing a functional model for cities impacted by a natural hazard: application to a city affected by flooding

“…However, in order to learn from urban crisis experience feedback, a methodology must be clearly set up so as to formalize the experience feedback, provide a model for the impacted city's failures, and understand the failure processes as well as the sequences and causal relationships thereof. This is not a negligible issue since urban systems appear particularly complex due to their many constituent subsystems, and the multiple organizations and governance (Lhomme et al, 2013;Toubin et al, 2012). The main scientific issue pertains to developing a model that might reproduce the complex operation and deficiencies of urban systems.…”

Developing a performance evaluation functional model for cities impacted by a natural hazard: application to a city affected by flooding

“…However, in order to learn from urban crisis experience feedback, a methodology must be clearly set up so as to make the experience feedback a formal one, provide a model for the impacted city's failures, and understand the failure processes as well as the sequences and causal relationships thereof.
