The novel compositional demand/supply resilience framework named Re-CoDeS (Resilience-Compositional Demand/Supply) generalizes the concept of disaster resilience across the spectrum of civil infrastructure systems by accounting not only for the ability of the civil infrastructure system to supply its service to the community, but also for the community demand for such service in the aftermath of a disaster. A Lack of Resilience is consequently observed when the demand for service cannot be fully supplied. Normalized resilience measures are proposed to allow for direct comparisons between different civil infrastructure systems at component and system levels. A scheme is introduced to classify component and system configurations with respect to their resilience. In addition to quantify the resilience of civil infrastructure systems, Re-CoDeS can be used to evaluate or design community risk mitigation strategies and to optimize post-disaster recovery.

A composite policy tool to measure territorial resilience capacity

“…The Re-CoDeS framework (Didier et al, 2017d) allows to quantify and qualify the resilience of a CIS-community system. It distinguishes two system layers, namely the supply system layer and the demand system layer, and the following metrics on a component and system level (composed of i ∈ {1...I} demand components or nodes, and j ∈ {1...J} supply components or nodes):…”

“…Table 1. Resilience-related system configurations, t 0 corresponds to the moment of occurrence of the disaster (adapted from Didier et al, 2017d).…”

“…In addition to quantifying a possible Lack of Resilience (LoR) of a CIS, it is essential to identify different system resilience-related configurations with respect to their vulnerability and recovery paths. The Re-CoDeS framework (Didier et al, 2017d) allows to quantify the resilience of such CIS-community systems and to identify possible post-disaster configurations. In the following study, different resilience-related configurations identified in the Re-CoDeS framework are presented, and their implications on the resilience of a CIScommunity system are discussed.…”

Towards Resilient Civil Infrastructure Asset Management: An Information Elicitation and Analytical Framework

“…Current resilience management (RM) research has moved forward from the conceptual debate to operational paradigms. In response, many resilience assessment frameworks and toolkits have emerged with representative studies encompassing the system-theoretic accident model and process (STAMP), functional resonance analysis method (FRAM), and resilience analysis grid (RAG) methods by Hollnagel, Woods, and others [4,5,26,27], 4R model [28], four-cornerstone model [4,29], three-stage resilience analysis framework [30], compositional demand/supply framework (Re-CoDes) [31], and physics-based framework [32] in order to enlighten the resilience assessment of urban infrastructure systems while the disaster resilience scorecard for cites [33], baseline resilience indicators for communities (BRIC) [34], and PEOPLES resilience framework [35] mainly address the community or regional-level disaster resilience analysis. These frameworks can explain how people deal successfully with unexpected and unforeseen events, highlighting the steps from work-as-imagined to work-as-done resilience and even promoting more strategic and tactical control within daily operations.…”

Resilience Evaluation Framework for Integrated Civil Infrastructure–Community Systems under Seismic Hazard

“…An integrated CICS is, in this model, represented by the EPSS, the TS and the community built environment. Seismic resilience of the EPSS-TS-Community system is modeled using the compositional supply/demand resilience quantification framework (Didier et al 2018a). The state of the electric power supply and demand in the EPSS-TS-Community system is modeled through the earthquake damage absorption and recovery phases.…”
