Quantifying disaster resilience of a community with interdependent civil infrastructure systems

Figures & data

Figure 1. Lack of Resilience of a system as defined in the Re-CoDeS compositional demand $D_{\mathit{sys},R/S}\left(t\right),$ supply capacity $S_{\mathit{sys},R/S}^C(t)$ and consumption $C_{\mathit{sys},R/S}\left(t\right)$ framework (Didier, 2018).

Figure 2. iRe-CoDeS algorithm to quantify community disaster resilience (a); the “distribute independent R/Ss” step of the iRe-CoDeS algorithm (b); and the demand/supply-based interdependency modelling algorithm (c) imbedded in the “distribute interdependent R/Ss” step of the iRe-CoDeS community resilience assessment algorithm (a).

Figure 3. Case study virtual community. Considered components in localities are Electric Power Plants (EPPs), Building Stock Units (BSUs), Base Station Controllers (BSCs), Potable Water Facilities (PWFs), Base Transceiver Stations (BTSs) and Cooling Water Facilities (CWFs).
