Modelling of critical resilience strategies to build critical infrastructure resilience using public-private partnership

Critical infrastructures are the spine of every functioning economy. These infrastructures are susceptible to disruptive events that interrupt their functional performance. Previous studies recommend public-private partnership (PPP) as an approach to building critical infrastructure resilience (CIR). In this study, a decision-making model is developed using system dynamics and partial least squares (PLS) for resilience strategies for building CIR using PPP. A questionnaire survey was conducted to collect data from 157 respondents, which were used for the data analysis. PLS and system dynamics were used to perform an empirical analysis in the study. This study identified five critical resilience strategies for PPP in CIR. The prominent strategies amongst them are collecting risk data, defining responsibilities, developing an inventory of critical infrastructure, developing a legal framework and financial reserves. The model provides a graphical view of the impact of the resilience strategies for PPP in CIR and how these strategies can positively impact CIR.
