When people pass through a narrow passage, once the perceived disaster will cause the crowd to generate pressure, to promote their competitive behavior, which lead to disorder and congestion. This is a very serious threat to the evacuation rate and export efficiency of the evacuees. How to optimize the crowd's guidance after taking these effects is an important issue. Based on the advanced micro-pedestrian...
In this paper, an agent-based simulation model is presented to simulate occupant evacuation in fire environment. Based on the agent technology, a computer program is developed to simulate and analyze the egress progress in large public buildings. Through simulation, the occupant behaviors and fire safety performance of different architecture plans can be investigated and analyzed in case of emergency...
The construction industry has been facing a paradigm shift to (i) increase; productivity, efficiency, infrastructure value, quality and sustainability, (ii) reduce; lifecycle costs, lead times and duplications, via effective collaboration and communication of stakeholders in construction projects. Digital construction is a political initiative to address low productivity in the sector. This seeks...
A novel emergency evacuation model based on a modified Particle Swarm Optimization was presented. The Linear Weight Decreasing Particle Swarm Optimization was introduced to simulate individualpsilas movement. Compared with social force model and CA model, the new model well performed evacuation result. A prototype system of emergency evacuation simulation was implemented based on Geographic Information...
