A framework for assessing the condition of crowds exposed to a fire hazard using a probabilistic model
Radianti, Jaziar; Granmo, Ole-Christoffer (Journal article; Peer reviewed, 2014)Allocating limited resources in an optimal manner when rescuing victims from a hazard is a complex and error prone task, because the involved hazards are typically evolving over time; stagnating, building up or diminishing. ... -
A spatio-temporal probabilistic model of hazard and crowd dynamics in disasters for evacuation planning
Granmo, Ole-Christoffer; Radianti, Jaziar; Goodwin, Morten; Dugdale, Julie; Sarshar, Parvaneh; Glimsdal, Sondre; Gonzalez, Jose J. (Lecture Notes in Computer Science;7906, Chapter; Peer reviewed, 2013)Managing the uncertainties that arise in disasters – such as ship fire – can be extremely challenging.
