Engineering Strategies for High-Availability Mission-Critical Facilities: A Survey

Mission-Critical Facilities in Diverse Domains investigates the key features, engineering requirements, as well as design provisions that allows continuous operation in high-consequence environments. The paper identifies that mission-critical facilities are becoming more important in various sectors, including data infrastructure, healthcare, defense, and manufacturing, and that they are sensitive to reliability, security, and resilience. It scans classification structures in terms of operational urgency and defines performance expectations which stimulate redundancy, real-time monitoring and disaster preparedness. Contributions of mechanical engineering are examined in reference to the redundancy strategy (including N+1, 2N strategy) and the task of adaptive controls in alleviating dynamic uncertainty. Structural and civil engagements are analyzed using modular construction and structural optimization practices that increase performance in terms of efficiency, safety and lifecycle. The research provides a multidisciplinary basis to the understanding and enhancement of mission-critical systems and balances design practices with current requirements of fault tolerance and always-on operation.
