Infrastructure asset management involves optimizing the performance, lifespan, and value of civil engineering assets over their lifecycle. Construct a theoretical framework elucidating the principles of infrastructure asset management, including asset inventory, condition assessment, and life cycle costing. Discuss theoretical models for prioritizing maintenance and rehabilitation activities, such as risk$-$based decision$-$making and optimization algorithms. Explore theoretical approaches to integrating asset management principles into infrastructure planning, financing, and regulatory frameworks, and analyze their role in promoting sustainability, resilience, and cost$-$effectiveness in asset management practices.
