Life-Cycle Performance of Infrastructure Networks

This chapter presents a brief overview of the assessment and management of networks incorporating risk, sustainability, and resilience measures in a life-cycle context. The framework covers predicting the component and system performance and the optimal interventions scheduling, including inspections, monitoring, maintenance, and/or repairs to enhance life-cycle performance and resilience. Various aspects of the life-cycle assessment and management framework are explained with special attention given to the performance assessment and the life-cycle optimization processes. Structural deterioration, extreme events, and climate change are considered and incorporated within the probabilistic framework. Furthermore, the chapter presents available methodologies for quantifying economic, social, and environmental metrics and resilience of networks. The presented framework supports the resilient and sustainable development of infrastructure networks and provides the optimal intervention decisions related to design, inspection, maintenance, monitoring, repair, and replacement of networks under multiple objectives and constraints.
