Passenger Flow Analysis And System Optimization Simulation Of High-Rise Hospital

With the rapid progress and development of China’s economy and society,the increasing mobility of urban residents and the serious shortage of urban land and construction resources,the proportion of high-rise buildings in the total number of all kinds of buildings in the country has increased rapidly.As a public building with high population density,more and more hospitals use high-rise buildings to save land resources and increase available space.High rise buildings make each functional area of the hospital more closely connected.Elevator is the carrier of vertical traffic flow in hospital,which often leads to congestion.A large number of people are waiting in front of the elevator hall.Reduce manpower and waiting time,improve the efficiency of the elevator system,so that patients and medical staff can enter the target area in the first time.This provides an important guarantee for the health and life safety of patients,but also can greatly improve the service efficiency of the hospital.In order to improve the efficiency of the elevator in operation and reduce the waiting time of passengers in front of the elevator hall,this thesis analyzes the hospital data,including the traffic mode time division,distribution fitting and passenger demand distribution,and then carries out the simulation experiment through the established simulation model to find the optimal partition under each traffic mode.Finally,the hospital is optimized based on human factors engineering and facility planning.In the aspect of data fitting,this thesis uses the actual data to identify the traffic mode.By comparing the fitting results of several kinds of passenger flow arrival distribution,it selects the herd distribution which can better fit the hospital elevator passenger flow arrival,and then uses the maximum entropy model to calculate the traffic demand distribution.The results are used in the simulation experiment.In the aspect of simulation model,this thesis uses Flexsim simulation software to build simulation model based on elevator operation logic,passenger queuing logic and partition control logic,and inputs floor structure parameters and elevator operation parameters into the simulation model.Establish the evaluation index based on the waiting time of passengers,input a variety of partition planning schemes into the Flexsim simulation model,analyze each analysis scheme,compare the average waiting time of passengers,and select the partition scheme which can improve the elevator operation efficiency better.In the aspect of hospital floor planning,this thesis uses SLP method in logistics facilities planning to solve out the layout planning with good results and brings in the simulation model to analyze the layout optimization effect.Based on the theory of human factors engineering,this thesis optimizes the optimal partition in the case of inter-floor traffic mode and verifies the optimization effect.
