A Simulation-Based Framework for Enhancing the Resilience of Maintenance Operations in Critical Infrastructure

Abstract

Resilience of maintenance operations in critical infrastructure present a significant challenge for future communities, particularly as the frequency and severity of human-made and environmental disruptions continue to escalate. This paper highlights the role of maintenance operations in ensuring the functionality of essential infrastructure components, with a focus on enhancing their resilience to ensure operational continuity. While existing research on improving resilience in maintenance operations remains limited, this study aims to bridge this gap by developing a conceptual framework that employs a simulation-based approach to improve decision-making in complex maintenance scenarios. The proposed framework is adapted from Bruneau et al. (2003) and grounded in the 4Rs resiliency theory. The framework is then applied to the case study of maintaining hospital elevators, focusing on the specific challenges and needs associated with maintaining this critical infrastructure. By integrating these principles, the proposed framework seeks to ensure that critical infrastructure remains efficient, reliable, and resilient in the face of unforeseen disruptions, ultimately supporting the long-term sustainability of essential services.
