I have an agent population within an agent, so I did the following:
- I Have created an agent type "Containers"
- I have Created another agent type "Products"
- I've Opened the "Containers" agent type and draged in "Products" to create a "pop_Products" within "Containers"
My question is the following:
Is there a template on how to create the database or how do u suggest to create the excel sheet? The information about the population of product I need are the name, amount of the batch and when it is produced.
There is no template. AnyLogic (=Java) is flexible to read any data, you just load it (and maybe preformat it) before creating your agents.
In your case, since you can define it upfront, the best way I see:
table "containers"
int column "container_id"
int column "product_id" --> link to which product
int column "numProducts" --> amount for your container
table "products"
int column "product_id"
String column "name"
Date column "productionDate"

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...
I need to implement a feature where the user will be generating reports dynamically.
In that feature, the user will be presented with an interface to select some specific modules. Each module will point to a set of tables internally.
Consider the following tables,
**Table Name : module_location**
location_id
location_name ->Contains a location name
**Table Name : module_streets**
street_id
street_location_id (F.K module_location.location_id)
street_name ->Contains street name in a location
If the user selects the module name Location, he is indeed choosing the list tables to be queried on(which is done internally)
In this case, module_location and module_streets (They will be joined by location id).
After selecting the Location module the user has to choose the set of fields which needs to be shown in the dynamic report, once generated.
So he'll be provided with an interface to select those fields. The names given in the interface will be alias names for the respective fields in the tables
ie,
The user will be presented with option to select the following
Location Name -> Corresponds to the field 'location_name'
Street Name -> Corresponds to the field 'street_name'
After selecting the required fields to be shown, the user will have to select some conditions like(count,sum etc)
Suppose, the condition is like Get the number of streets in a location, the user will have to add condition count against the option Street Name.
After selecting the conditions, the user have to simply click the submit button in-order to generate the report.
The issue I'm facing here is how to decide the columns to be grouped. If this is done manually, I know that I need to group the location_id to get the count. So how can I do that, if the query is generated dynamically?
Kindly help. The database I'm using is postgresql8.4
In Filemaker Pro 12, I am trying to write a formula for a calculation field that will sum a field in a related table based on another field in that same related table. The normal Filemaker sum equation would look like this:
Sum (Assets::Asset Quantity)
However, I need to specify that only quantities that are related to a field named Asset Type with a value of "Building" will be used to filter the values in Asset Quantity that will be used in the sum.
There are a couple of ways that you could do this:
A new Calculated field
First, you could add a new Calculation field to your Assets table called, say, Building Quantity, with a Calculated Value of:
If (Asset Type = "Building" ; Asset Quantity ; 0)
And then you can use the sum of this new Building Quantity just like you were using Sum(Assets::Asset Quantity) before.
A new relationship
Second, you could add a new Calculated field to your main table with the value always equal to "Building" and then add a new table occurrence of the Assets table. We'll call it "BuildingAssets" and set the relationship so that your IDs match and also your new "Building" field matches the Asset Type
Summary ID \____________/ BuildingAssets::Summary ID
BuildingText / \ BuildingAssets::Asset Type
Then you will use
Sum (BuildingAssets::Asset Quantity)
instead of Sum (Assets::Asset Quantity) so that you only pull the Building types through.
ExecuteSQL
Finally, FileMaker 12 introduced the ExecuteSQL step. This may be the most elegant way to do the above because it doesn't involve changing any schema. The statement would be somethign like:
SELECT
SUM (Asset Quantity)
FROM
Assets
WHERE
Summary ID = ID AND
Asset Type = Building

I'm new to reporting services so this question might be insane. I am looking for a way to create an empty 'template' report (that is basically a form letter) rather than having to create one for every client in our system. Part of this form letter is a section that has any number of 25 specific fields. The section is arranged as such:
Name: Jesse James
Date of Birth: 1/1/1800
Address: 123 Blah Blah Street
Anywhere, USA 12345
Another Field: Data
Another Field2: More Data
Those (and any of the other fields the client specifies) could be arranged in any order and the label on the left could be whatever the client decides (example: 'DOB' instead of 'Date of Birth'). IDEALLY, I'd like to be able to have a web interface where you can click on the fields you want, specify the order in which they'll appear, and specify what the custom label is. I figured out a way to specify the labels and order them (and load them 'dynamically' in the report) but I wanted to take it one step further if I could and allow dynamic field (right side) selection and ordering. The catch is, I want to do this without using dynamic SQL. I went down the path of having a configuration table that contained an ordinal, custom label text, and the actual column name and attempting to join that table with the table that actually contains the data via information_schema.columns. Maybe querying ALL of the potential fields and having an INNER JOIN do my filtering (if there's a match from the 'configuration' table, etc). That doesn't work like I thought it would :) I guess I was thinking I could simulate the functionality of a dataset (it having the value and field name baked in to the object). I realize that this isn't the optimal tool to be attempting such a feat, it's just what I'm forced to work with.
The configuration table would hold the configuration for many customers/reports and I would be filtering by a customer ID. The config table would look somthing like this:
CustID LabelText ColumnName Ordinal
1 First Name FName 1
1 Last Name LName 2
1 Date of Birth DOBirth 3
2 Client ID ClientID 1
2 Last Name LName 2
2 Address 1 Address1 3
2 Address 2 Address2 4
All that to say:
Is there a way to pull off the above mentioned query?
Am I being too picky about not using dynamic SQL as the section in question will only be pulling back one row? However, there are hundreds of clients running this report (letter) two or three times a day.
Also, keep in mind I am not trying to dynamically create text boxes on the report. I will either just concatenate the fields into a single string and dump that into a text box or I'll have multiple reports each with a set number of text boxes expecting a generic field name ("field1",etc). The more I type, the crazier this sounds...
If there isn't a way to do this I'll likely finagle something in custom code; but my OCD side wants to believe there is SQL beyond my current powers that can do this in a slicker way.
Not sure why you need this all returned in one row: it seems like SSRS would want this normalized further: return a row for every row in the configuration table for the current report. If you really need to concatenate then do that in Embedded code in the report, or consider just putting a table in the form letter. The query below makes some assumptions about your configuration table. Does it only hold the cofiguration for the current report, or does it hold the config for many customers/reports at once? Also you didn't give much info about how you'll filter to the appropriate record, so I just used a customer ID.
SELECT
config.ordinal,
config.LabelText,
CASE config.ColumnName
WHEN 'FName' THEN DataRecord.FirstName
WHEN 'LName' THEN DataRecord.LastName
WHEN 'ClientID' THEN DataRecord.ClientID
WHEN 'DOBirth' THEN DataRecord.DOB
WHEN 'Address' THEN DataRecord.Address
WHEN 'Field' THEN DataRecord.Field
WHEN 'Field2' THEN DataRecord.Field2
ELSE
NULL
END AS response
FROM
ConfigurationTable AS config
LEFT OUTER JOIN
DataTable AS DataRecord
ON config.CustID = DataRecord.CustomerID
WHERE DataRecord.CustomerID = #CustID
ORDER BY
config.Ordinal
There are other ways to do this, in SSRS or in SQL, depends on more details of your requirements.
