I am trying to create an agent based model. I have a GIS shapefile for a county that consists of 190 census tracts. I have uploaded the shapefile into AnyLogic and have 190 regions in Main>Presentation>level>map. Now Using first 15 regions (census tracts), I want to create a big region (named as neighborhood). Once I select 15 regions and right-click, it gives me an option to create collection. I saw in AnyLogic help page, about functions for multi-region (r.g.; boolean addAll(Collection regions)). But I don't know where should i write this code.
I really appreciate your help!
I have selected 15 regions and form a collection. But I want a region.
The multiregion only works if you use the search functionality... so what you need to do is to create a variable of type GISMultiRegion initialized with
new GISMultiRegion()
Then on Main startup you have to add the regions you want
if it's called multi you can do
multi.add(gisRegion1);
multi.add(gisRegion2);
And so on
or you can create a collection of all your regions and do
multi.addAll(collection);

I would like to load my trucks on specific docks like loading truck A on dock 50. After I insert population loaded from database I get the error that it doesn't find my storages and it cant't calculate the space of my palletracks/ docks. Could it be that whenever I insert a population via database that the program ignore the other parameters of the agent like my storage? Before I insert the database, it works fine.

Make sure to load all parameters from the dbase table in the properties of your agent population under "Agent parameter mapping" (visible in your second screenshot).
The AnyLogic help explains more on how this works but you essentially tell your agents which parameters should be filled from which table column.
I would like to create a database to load my trucks at a certain time and on a certain dock. So for example truck A should load on dock 1 at 6 am. The problem is that I don't know how to get the different IDs of my docks. I create a parameter called id but don't know which ID my different docks have which I write into my database.
Database
]1
agent/population_dock
Create a new dbase table "docks" with an int-column "dock_id". Fill it with as many docks as you want to create and give them an id number.
In your existing table, link the "id" column to that new table "dock_id".
When you create "Dock" agents in your population "loadDocks", you can select "loaded from database". Create 1 agent for each record in table "docks" and map the "dock_id" column to your parameter "Dock.id".
Now each dock knows its id.
Lots of AnyLogic example models use this setup, so check these out as well (search for "database"). And read around in the help, this is documented very well :)
OK... let me retry the question.
I'll just walk through the steps I (wrongly) assumed would work.
Create a data table in excel with passenger info (id, flight_time, type, class, qty...), note that the table is sorted by id... not flight_time.
Import this database into anylogic.
Create a population of agents (Passenger/Passengers) from the data table (one/row).
Create a schedule that addresses the Start Column as flight_time and Value column as qty (for this job I'm only sending one passenger at a time therefore qty = 1 for each row).
Set the pedSource to arrive according to schedule and to use the Passenger Agent as the New pedestrian.
So here is where I'm losing it. When I run this model the new Passengers do not have any parameters associated from the data table. The pedestrian id is some weird number (say 3000 or so). I can click on the Passengers icon during run time and scroll through the created agents (all of the parameter data is there and correctly assigned), but I'm not sure how to associate the new Agents in the run-time model with the population of Passengers agents.
Am I missing a step here? I was thinking that if I import a population of agents from a data table and then have each show up at a particular time in the model that I could then do some calculations with regard to each such as ped.exitTime = time() - ped.flightTime - ped.bufferTime.
I'm just not understanding why the table data is not available for use during run-time through ped? Is there another mapping step that must be performed to push the data to the ped agnets?
I'm at an impasse at this point. I hope this question is described more clearly and your feedback is appreciated.
Several things are wrong here.
You do not create agents in a pop first and then try to reuse them in a PedSource. The latter creates agents itself.
You don't seem to create pedestrians but just agents
you are not mapping the data to parameters
Quick guide to help:
create custom agent type "MyPed" . Make sure its "use in flowchart" property is set to "Pedestrian"
add 1 param into "MyPed" for each dbase table column
set your PedSource to "calls of inject()" function for its arrivals
delete your schedule, you cannot get the data you need
USe a DynamicEvent. Include 1 parameter argument for each dbase column. On Startup of main, loop across all dbase entries and create a dynamic event with the current row-data.
in the action of the DynEvent, call myPedSource.inject(1) and then manually fill that ped with the data from the arguments
This is not straightforward, especially the DynEvent stuff. So do more research in the AL help to understand these and how they work, check example models...
continuing a project I have posted a few questions for already are you able to have a more precise definition of what a dropdown is populated with?
I am using FM Starting Point and have a Projects, Estimate and Task table. A project can hold multiple estimates and tasks. Estimates contain multiple lines (stored in a separate table).
When In a Project you can add a task for that project. What I want to do is replace the field that gives the task a name with a list of lines contained within the estimates related to the project i have selected to add the task from.
I have created a dropdown and using the inspector got it to display all estimate lines but somehow I need to write a function that will only select lines from estimates that are within the project and also only estimates that have a field set to "active" for example.
what I am struggling with is where I can programme such a thing? In the inspector, you are limited to displaying a value and cant programme in a statement. I have tried a script that executes OnObjectEnter or OnObjectModify but that doesn't appear to work.
Any ideas where I can enter a more complex set of rules as to what populates a dropdown?
Create a relationship with the criteria you need. Base the value list for the dropdown on this relationship.
As for display, The value list's second field can be from a calculated field with any data or several other fields stringed together if no single field is sufficient. The first field should be the ID.
I am working on a project where we are going to be looking at finding the shortest/fastest route from point A to point B. I've been looking at the tables generated by the osm2pgsql. And I'm wondering how would I represent a road obstructed after the osm has been loaded into our database. Our project will rely on osm to map out all of the roads we will also have an operator looking at live video footage of roads. At which point if the operator see's a road is obstructed we want to update the database to reflect this road obstructed say by a downed tree.
I've been looking at all of the columns and the only one that stands out in my head is barrier. I have been unable to find any documentation on what each column represents and how pg_route takes each into consideration when creating a route. What I'm looking for is a column that when pg_route looks in the database and sees a road it says oh that roads blocked skip it?
This is good question for gis.se...
First thing is pg_routing can't route via data generated by osm2pgsql - this data is not a network. You need data generated by osm2po or osm2pgrouting and this data is quite different.
Second thing is - there is no such column. In every pg_routing function you're passing sql which will select data for route search so you're deciding which edge will be in this dataset and which not - it's not a problem to add extra column to table with edges.
Here is link to pgrouting workshop it will guide you through all process from import of data to first generated route. It's using osm2pgroutin to import data, but I suggest you use osm2po instead.
So as Jendrusk mentioned, when you generate a route you will pass the function a SQL query to select the edges for the graph you want to solve, 'select * from edges where the_geom && <bbox>' You can model blockages using point and radius, lines, or polygons that you want the route to avoid by adding to the query above avoidance zones like:
'select * from edges where the_geom && <bbox> and not st_dwithin(the_geom, point, radius) and not stdwithin(the_geom, line_or_polygon, 0.0)'
If you have lots of these avoidances then put them in a table and do a join to eliminate the edges that are used to build the graph. If the edges are not there the route is forces to find a way around the avoidance.
