Water Demand Modeling And Simulation For Urban Residents Based On AnyLogic

The rapid growth of urban population and the general shortage of water resources are common problems in the world at present.With the development of urban development principles such as water city and people,it has become the focus of academic research and urban management practice to fully implement the strictest water resources management system from water supply management to water demand management.This paper focuses on the living water demand of urban residents,systematically analyzes the behavior and process of using water,and establishes the living water demand system model based on the Agent modeling and simulation method.The specific contents are as follows:(1)By investigating basic data such as individual water use behavior and household water use characteristics,subdivide the water use process and analyze its behavior characteristics,design the data structure and micro water demand behavior of individual and household agents based on the micro entity water use mechanism,and use the Agent modeling method to realize the dynamic simulation of urban residents' living water demand process;On this basis,the paper further discusses the factors that affect the residents' demand for water,including regional population change,family structure change and temperature change,and realizes the modeling of regional demand system.(2)Tongzhou district,where the vice center of Beijing is located,has been suffering from severe water shortage for a long time.As an area with a large number of directional population migration under the two-wing pattern,it is facing great pressure of water consumption.This paper takes Beijing sub-center as the target area,sets the relevant property parameters such as residents' age,gender,income level and residents' microscopic water demand behavior parameters based on the statistical survey data on the basis of the model of residents' living water demand system,and realizes the simulation of residents' living water demand in the target area from 2016 to 2025.(3)Combined with wisdom city development idea,based on the application prospect of intelligent measuring equipment with water,living water system model is established,through the design of water data visualization interface,real-time,high resolution data with water for residents living water demand behavior and the effect of setting the water saving consciousness of resident parameters,adjust the water act.According to the simulation results,we can see the change and trend of residents' and communities' water demand.
