In a simulation study, Taylor and Yu [6] found that categorizing one continuous v...

Recent incidents such as the Asiana Flight 214 crash in San Francisco on July 6, 2013 have brought attention to the need for safer aircraft evacuation plans. In this paper we propose an emergency aircraft evacuation model based on a revision of the Particle Swarm Optimization (PSO) algorithm. By introducing an attraction-replusion force from the study of swarm modeling we are able to consider r...
