碩士 === 國立中央大學 === 環境工程研究所 === 107 === In this study, the software Simulex was used to simulate that when there were fires or other emergencies on the four floors in a semiconductor technology factory, the time required for all the personnel to leave the accident floor to the safe area on the first floor using the emergency exit between each floor or other safety facilities such as a safety ladder, and also the behavior of the people during evacuation. The simulation was performed using the building layout drawn by a computer-aided design software AutoCAD as the architectural boundary, and the straight-through stairs or emergency escape stairs as the main refuge facilities. In addition, two scenarios were included in the simulation: A) There is no fire incident. All personnel from each floor evacuating to the exit on the 1F with equipped three scape ladders. B) Presumed there is a fire incident at 1F that caused safety ladders between the 1st to the 4th floor unavailable. Personnel were evacuated to the exit at 1F through other feasible routes. Results of the simulation showed that: A) 810 members took total of 4 minutes and 56.6 seconds to evacuate using three safety ladders; B) 810 members took total of 5 minutes and 31.5 seconds to evacuate using two safety ladders. It can be seen that in real evacuation situations, people may not be familiar with the environment and take the wrong routes due to blind behavior; others might take the backward route to the entering, instead of using the nearest exit, due to homing ability inherent by human nature. Therefore, the simulated escaping time should be normalized and increased by a factor of 1.5 as the safety coefficient. Based on the simulation results, two suggestions were proposed: 1) improve simulation coverage and conditions of Simulex software to match escaping scenario in the real world; 2) verify the results with real exercise and experiment to understand the differences between the simulated results and real situation for future emergency evacuation planning.
