Abstract

Criteria and indicators are frequently used for assessing the resilience of critical infrastructure (CI). Moreover, to generate precise information on conditions, the assessment designed for CI resilience could rely on indicator systems. However, few practical tools exist for guiding CI managers to build specific indicator systems for considering real cases. Therefore, the main objective of this study is to develop a step-by-step guide that contains guidance on operational steps and required resources for criteria and indicator setting, reference definition, and data collection. This guide enables CI managers to build systems of indicators tailored to different real cases. This guide could assist CI managers in their decision-making process, as it is structured based on a multi-criteria framework that takes into account the cost–benefit analysis and side effects of implementable actions. This guide could furthermore advance the application of indicator-based CI resilience assessment in practical management. In addition, this study provides an example to demonstrate how to use this guide. This example is based on specific circumstances for the Nantes Ring Road (NRR) network: when the ring road is flooded and closed, the road network manager suggests alternative roads to the public. An indicator system consisting of 4 criteria, 7 sub-criteria, and 11 indicators was built for these circumstances using the guide developed in this paper. This example relates to criteria and indicators in the technical, social, and environmental dimensions and involves 62 676 data points. [ABSTRACT FROM AUTHOR]

Abstract

Criteria and indicators are frequently used for assessing the resilience of Critical Infrastructures (CIs). However, the application of the concept of CIs resilience in practical disaster management is challenged by the lack of operational tools. An operational tool should enable the establishment of an organized system of indicators and optimising operational practice. Therefore, to address the operationalisation of resilience assessment, the main objective of this study is to develop a step-by-step guide for the creation of specific indicators aimed at different practical situations. This guide can assist CIs managers in their decision-making as it is structured based on a multi-criteria framework that considers the various interests of stakeholders. This guide includes the methods for Criteria and indicators setting, reference definition, and data collection. Furthermore, this study presents an example of the application of the guide. This example is based on a given scenario focusing on the Nantes Ring Road (NRR) network: when it is flooded and closed, the road network manager suggests alternative roads to citizens. The created indicators, based on this scenario and involved 62 676 data, relate to potential damages and costs-benefit and involve technical, social, and environmental dimensions.

Abstract

International audience; In the " Village Parisien " district, in Champigny-sur-Marne, several sewer overflows have been observed. The district (23 ha) is mainly occupied by detached private housing. On 30% of the houses, the county administration installed cisterns for roofs rainwater harvesting. This paper describes a hydrological analysis of the district before and after cisterns installation. We calibrated the SWMM 5 hydrological model using a genetic algorithm, on the basis of sewer flow measures before and after the installation. Simulations show that, although cisterns affect the district hydrology, they can not prevent sewer overflows in case of heavy rain events.

Abstract

National audience; This paper deals with databases and Geographic Information System (GIS) and their use to help in environmental management of sewer systems in medium sized cities. Even though GIS are generalised in those cities, their use as decision aid tolls is restricted. The two main reasons are due to the dispersion and the imperfection of data. Within the ambit of a project funded by the French research ministry, several elements of methodology were developed in order to elaborate a strategy of information collection. The adaptation of the data model in order to assess the environmental profile of sewer systems and the treatment of imperfections in database will be presented.

Abstract

Structural covers for transport infrastructures and routes in an urban environment answer to public policy issues relating to urban questions, real estate questions, etc. The multiplicity of actors, multi-scalar consideration and integration of temporality, in addition to contextual and technical constraints mean that the decision in the case covers urban infrastructure is often a chaotic process and rarely concerted. In order to offer evaluation methods of this particular object, it is necessary to understand and to interpret the object in its urban environment In this perspective, modeling work of structural cover is undertaken. Using conceptual models enabled the identification of a nuisance/inconvenience process between environment's elements. Structural covers constitute a possible response to the conflict and the problem about the coexistence of the infrastructure and the urban space. Its integration into the urban system is a complex problem. Thus, questioning and reflection around the methods and tools of structural covers evaluation, are naturally oriented towards the study of complex systems. To understand and represent the operation of the complex system coverage, functional analysis is used. [ABSTRACT FROM AUTHOR]
