Речь идет о стихийных бедствиях, таких как наводнение, которые можно спрогнозиро-вать за несколько часов до того, как они произойдут, чтобы можно было организовать эвакуа-цию населения. Эвакуация означает, что люди в районах бедствия должны покинуть эти рай-оны и добраться до укрытий или убежищ. Представлен анализ процесса принятия решения обэвакуа...

Fuzzy logic is a modern tool which can be used to deal with uncertainty inherent in evacuation emergency tasks. During evacuation, the main goal is to transport the maximum amount of aggrieved from the hazardous area to the secure shelter, considering arc capacities and dynamic flows. In most cases, evacuation tasks do not consider storage at inter...

Emergency evacuation modelling is a topical issue, which has attracted increasing interest over the last years. Today, flow theory-based approaches to macroscopic evacuation enable researchers to find a solution to optimization problems, considering aggrieved as a homogeneous mass. The main difficulty in constructing evacuation scenarios is the nee...
