Study On Spatial Layout Efficiency Of Community Center Based On Elderly Behavior Simulation

The degree of aging in China is increasing,home care and community support for the elderly are more important.At present,there are many problems in community service facilities,such as uneven resource allocation,repeated construction,low utilization rate of some facilities,scattered distribution,single services,poor investment attraction and so on.As a “one-stop” community service facility,community centers can realize the synergistic effect of public welfare services and economic benefits.Under the background of the transformation of consumption model and the exploration of service-oriented government,the comprehensive service functions contained in community centers have great potential to solve the needs of the elderly.This paper takes the centralized community center as the research object,investigating the behavior habits and needs of the elderly in two typical community centers in Guangzhou by questionnaire survey,behavior observation,behavior tracking and other methods,and puts forward various functional suggestions to meet the needs of the elderly.Using the agent behavior simulation technology,based on the behavior data of the elderly in the community center,the simulation model of the elderly behavior was established in Anylogic platform,and the evaluation indexes were designed to simulate and compare the different spatial layout between Fang He Community Center and the Cheng Nan neighborhood center in Guangzhou.According to the simulated data,the spatial layout suggestions suitable for the usage behavior of the elderly are put forward.The main contents include: The first chapter are the research background,purpose and significance,definition of relevant concepts,main content,methods and framework;The second chapter is a theoretical study,including the development history and trend of community centers,relevant support policies,research reviews of community centers and behavior simulation,and cases studying of spatial layout types of community centers.The third chapter is the research process design,including the behavior simulation principle,method and software selection,simulation rules and the design of the elderly behavior simulation process;Data and research methods needed for simulation,and the selection of research objects.Finally,the existing evaluation methods of spatial layout were summarized,and four indexes of spatial layout utility evaluation were constructed,including spatial activity,average use time,space utilization rate and average moving distance.The fourth chapter is the part of investigating the behavior data of the elderly.Questionnaires were used to investigate the daily habits of the elderly,the use of space,the relationship between purpose and space,functional requirements and evaluation data,which were used as the basis for functional optimization.Using observation to grasp the behavior types,behavior spatiotemporal characteristics of the elderly,as the basis of the use purpose and space selection in the simulation;Through behavior tracking,the behavior flow rules and duration are understood,which are used as the basis for the formulation of simulation rules.According to the results of the survey,the function suggestions of the community center for aging were put forward.The fifth chapter is the layout optimization and simulation evaluation of the community center.Taking function,area,number of floors and distance as parameters,a simulation model of the behavior in the community center building was established,and the matching degree between the model and the survey data was verified.The function optimization and spatial layout scheme are evaluated through simulation.The results show that: the juxtaposition of public service and commercial floor which connected by public space can increase the number of commercial users;The activity space is set in layers which unable to gather users,resulting in reduced utilization of large space;The more use function of the space,the higher the utilization rate;With the increase of service content,the average usage time of the elderly increases;The use ratio of leisure activities spaces is higher than cultural services spaces.The main results are as follows: 1.Starting from the behavior investigation of real scenes,this paper summarizes the needs and behavior rules of the elderly in the community center,and puts forward the functions that the community center should have for aging.Second,The feasibility of the simulation parameters of the elderly behavior was verified by applying the survey data.The architectural scheme of different spatial layout is evaluated quantitatively.This paper explores the technical idea of combining computer simulation technology with environmental behavior data to optimize the layout of plane functions.
