Abstract
Strategic infrastructure plays a key role in the functioning of urban areas, especially when dealing with emergency response to natural disasters. Urban areas and their infrastructure are threatened by natural hazards, which is likely to be exacerbated by climate change and intense urbanization in the near future. The UK National Flood Resilience Review (2016) committed £2.3 billion to be invested to reduce flood risk, of which £12.5 million specifically for temporary defenses. At present, the state of the art does not provide a proven efficient methodology specifically designed to optimally invest these resources; in light of this, a consolidated urban planning spatial optimization methodology is originally used for allocating resource storing space and ultimately optimize flood emergency management. This study developed and applied a RAOGA (Resource Allocation Optimization Genetic Algorithm) to balance the particular trade-off between simultaneous minimization of response time and costs. The presented optimization framework balances several competing tensions that include: (1) the identification of, and the cost of using, possible sites (warehouses) to store flood temporary defenses; (2) the identification of strategic infrastructure location; (3) transport optimization for moving emergency response resources into place. The methodology is applied to a regional case study (Yorkshire, UK) as proof of concept. Such a framework has the potential to lead a new generation of mathematically-based emergency response planning, targeted to policy makers dealing with urban planning and emergency management.
