Optimal Critical Infrastructure Retrofitting Model for Evacuation Planning

Optimal Pedestrian Path Planning in Evacuation Scenario

Simulation of evacuation plans is a relatively complex problem. It is necessary to simulate a number of separate processes which interact in the result. Namely, they are pedestrian-pedestrian interactions, pedestrian-static object (e.g. wall) interactions and pedestrian-environment (fire, smoke, etc.) interactions. In this case, the evacuation simulation is controled on the microscopic level. M...

A two-stage mathematical model for evacuation planning and relief logistics in a response phase

Crises and natural disasters are always existed in human history, and continue to exist in the future; therefore, people are always affected by these natural disasters. Hence, evacuation planning after natural disasters (e.g., earthquakes, floods, tsunamis, fire, storms, warfare and nuclear explosions) is vital. Given that natural disasters cause irreparable financial loss and the loss of life ...

Planning and Retrofitting for Recurrent Floods

Natural hazards threaten everybody living in vulnerable areas. With the increasing concentration of people, infrastructure and facilities in them, urban areas are becoming particularly vulnerable to hazards (Pelling 2003, Perrow 2007). Hazards become disasters when they impact on human beings and their artefacts. The people and institutions involved include, amongst others, those participating ...

Sink location to find optimal shelters in evacuation planning

The sink location problem is a combination of network flow and location problems: From a given set of nodes in a flow network a minimum cost subset W has to be selected such that given supplies can be transported to the nodes in W . In contrast to its counterpart, the source location problem which has already been studied in the literature, sinks have, in general, a limited capacity. Sink locat...
