extends uchicago.src.sim.engine.SimModelImpl

This variation of the segregation model was created to see what effect agents preferences for another group have on the outcome of the model. In a sense this is loosly based on Sakoda (1971) paper. The previous models have all focused on agents wanting to be in an area where at least a certain percentage of the neighbouring agents are of the same type as themselves with no consideration of the other group. This model will explore how the pattern of segregation alters if agents have preferences for its own group and for another group. The model could therefore be considered more of Sakoda-type(1971) than that of Schelling-type (1971) of model. The only thing that was changed was what makes the agent satisfied: For agents who want mixed neighbourhoods, a dislike for their own group Red Agent is satisfied if: Red Population % of neighbourhood <=50% and Blue Population % is >=50% Blue Agent is satisfied if: Blue Population % of neighbourhood <=30% and Red Population % is >=70%

Constructor Detail

SegGISModel

public SegGISModel()

Method Detail

main

public static void main(java.lang.String[] args)

begin

public void begin()

Calls the buildModel, buildDisplay and buildSchedule methods the method initialises the repast model In this order. Therefore things created in build model are seen in builddisplay etc.

buildModel

public void buildModel()

buildDisplay

public void buildDisplay()

setSnapShotRecording

public void setSnapShotRecording()

Created to save time when images are wanted when running a simulation. Images are stored in the same location as the shapefiles.

takesnapshot

public void takesnapshot()

Record snapshots of all of the displays, so one does not have to select the displays to be saved manually

buildSchedule

public void buildSchedule()

Schedules the execution of the specified method (ie step)on the specified object(ie this model) to start at the specified clock tick and continue every tick thereafter.

step

public void step()

Step method tells the program what to do at evey step THis therefore should contain infomation about agent movement, what agents are where etc.

preStep

public void preStep()

postStep

public void postStep()

numberOfHappyResdientAgents

private void numberOfHappyResdientAgents(java.util.ArrayList residentAgentsList)

Used to calculate the number of unhappy agents in the area. Make a new iterater based on residentlist, get each residents happyness and then count them. Then print out the totals.

densityStats

private void densityStats(java.util.ArrayList urbanAgentList)

Used to calculate max and miniuim density of Urban agent along with average density of the area. Uses popDensity method from * Urban Agent *

getNeighborAgents

public java.util.ArrayList getNeighborAgents(int[] neighbors)

setup

public void setup()

reset

public void reset()

The reset mmethod is called whenever the model is reset. Everything is reset to null

getSchedule

public uchicago.src.sim.engine.Schedule getSchedule()

Schedule manages the execution of BasicAction accoriding to the simulation clock. Actions schedulled on a schedule will be executed in a random order.

saveShapefile

public void saveShapefile()

createShapefileForAgents

public void createShapefileForAgents()

creates a new point shapefile containting all the resident agents this uses information from the Resident class specifically information in the gisPropertyList()each element in the dbf file needs a get and set method in a similar way to reading in and storing changes in the urban agent. Need to rewrite anl.repast.gis.data.OpenMapData class specifically writeDbfFromAgents() becuase write to string was not working. Also writeAgentsNoShp() so a point file would be created from an OM circle otherwise the file would be of type polygon.
