| 英文摘要 | Due to increasing medical demands in China, large hospitals, especially those located in metropolis, become overcrowded, which definitely degrade patients’ experience. The high efficiency of pedestrian flow system in hospital can extremely reduces pedestrians’ time cost and distance cost, thus avoiding overcrowding and improving experience. However, due to the particularity of pedestrian flow system in hospital and less research focus on this field, there are still not efficient control methods as well as accurate computational model. How to optimize the pedestrian flow system in large hospital? How to construct computer microscopic simulation of pedestrian flow system? In this paper, the pedestrian microscopic model is built and design proposals are discussed, which provides decision support for the reconstruction and management of pedestrian flow system in large hospital in China. Firstly, the reasons that lead to current problems of pedestrian flow system are given in detail. Through comparison between large hospitals in China and in developed countries as well as the analysis of difference between pedestrian traffic in hospital and in other public buildings, the causes to problems of pedestrian flow system in large hospital in China are presented. Secondly, the pedestrian simulation model based on multi-agent theory is built. The features, structures and modeling approaches are explained in detail. Then, based on attributive characters, the Agent model is constructed. By Repast platform, simulation experiments are realized, including horizontal passage, bottleneck and registration office. Accordingly, the flow characteristics of pedestrian traffic in hospitals are analyzed and summarized, which lay the foundation for the following computational experiments. Finally, the design of pedestrian flow system is discussed. Based on the analysis of internal space design, three approaches, including distribution of department and cashier, design of corridor are presented. With Matlab platform, computation experiments based on queuing model are carried out. Based on simulation results, diverse design proposals are evaluated, which provides feasible calculation model and evaluation methods for pedestrian flow systems. |
