On the Crowded Places Multi-Exits Emergency Evacuation Model and Algorithm
نویسندگان
چکیده
Emergency evacuation in the crowed places was discussed, under the different analysis, description, and relevant research backgrounds. First, the evacuation shortest path optimization model was established. Then the optimization solution results obtained by using of software Lingo were analyzed and verified. Finally, the quantitative solution results were conversed to the version of variable, so that the results more suit with the actual situation. This research provided a basis for the practical application of the model to develop an emergency evacuation plan.

Introduction Recent natural and man-made disastrous events underscore the importance of emergency evacuation planning and management for buildings and facilities (Averill et al., 2005). Although building codes include provisions for egress design, their prescriptive nature poses many limitations in terms of providing effective evacuation for specific buildings, each of which is unique. Human be...
