Multi-criteria decision-making framework for evaluating life-cycle resilience of power-generating plants

Power generating plants, indispensable for modern societies, remain vulnerable to seismic disruptions. While efforts have been made to mitigate seismic risks, ensuring the life-cycle resilience of these critical infrastructures remains paramount. This study introduces a comprehensive framework, BCA-MCDM, for assessing power plant resilience, considering a multi-criteria approach encompassing costs, benefits, downtime, payback period, and repair costs. By integrating probabilistic-based assessments and cost–benefit analyses, the framework facilitates the identification of optimal seismic mitigation strategies. Key findings emphasize the significant influence of business downtime on life-cycle damage, stressing the need for expanded insurance coverage. The framework quantifies total losses by combining direct and indirect costs, providing a robust basis for decision-making. To enhance the framework's applicability, future research should explore the integration of fuzzy TOPSIS methodology and consider additional factors. This study contributes to the development of resilient power plants by providing a robust assessment tool for decision-makers.
