I've a problem with a simulation in anylogic.
I have an item (agent) that must be processed by a resource, the result of this service block is the starting object and two different documents which are processed in two separate offices and which at the end of the flow will have to be linked to the article in question.
I can't find a way to do this division into 3 different agents, or in general, to model this flow.
Thanks in advice
You can use 2 split blocks to generate 2 independent documents and connect them through a variable or link to agents... maybe each original agent has an id and the copies in the split block will have something like agent.id=original.id;
Then after, when the documents are processed you can check for which ones have the same id to merge them into an article...
but if you want to get more complicated, there's also the following option:
create 2 enter blocks (enter1 and enter2), one for each document. I will assume your documents correspond to 2 different agent types called Document1 and Document2
On each one of the agent types, you will add a link to agents in order to be able to connect the documents to each other. Read more on link to agents on the help documentation if you don't know what that is.
At the end of the service block, on the on exit action, you can do the following:
Document1 doc1=add_Document1();
Document2 doc2=add_Document2();
doc1.linkToDoc2.connectTo(doc2);
enter1.take(doc1);
enter2.take(doc2);
I don't know if your original agent has to be connected, but you would follow the same principle to do that.
Later, you can just check if the connected docs are completed in order to join them in an article again.

In my model I only want to batch agent which are at the same location. So my source block generates the agents according to a database to a specific node (which is sometimes different for agents), now I want the agents that occur at the same node to batch in sizes of 2 and the one that are left over need to be batched alone.
How can I model this, I know that I can use the selectoutput (which says for example if location=node1 use this output etc) option, but do I than have to add for example manually 100 outputs if I've 100 different locations where the agents start or is there a more simple solution for this problem?
Added later:
Or is there another way to model my idea:
So I'm simulating an hospital environment, where logistic employees (in this case the transporter) based on predefined times collects the thrash on certain areas for example the databaserow I show in the picture below:
At 9:50, the thrash at thrash collection point at LAB_Office_2_H_T_N can be collected by the logistic employee.
So in my model I create this 2 agents (which are 2 containers, last column) based on this time and seize a transporter to collect this thrash. Since a logistic employee is able to collect 2 thrash in one time I want to batch it and let the logistic employee collect 2 thrash containers at once.
After that he transports it to the thrash dump area and is released.
The colors changed after the added information. You can use pickup and dropoff blocks instead. You can define your node requirements in the condition cell. You can use local variables like container and agent to code whatever you want. Or use "Quantity (if available)" option. There you can programmatically define how many units will be picked up by using your own function.
I'm creating a model based on the product delivery example provided by AnyLogic. In my own model, I want a truck to deliver multiple orders in one trip instead of one. My process diagram is shown below. Here, an order enters via the enter block and several orders are accumulated in the batch block. Every order has a specified destination. How do I model the truck such that it combines two orders and move to the nearest delivery location first and then the second etc?
The main problem is that I don't know the code that accesses the parameter "Delivery location" in each order.
enter image description here
enter image description here
Additional information:
The orders agents are generated and the delivery location is stored in a parameter called "client"
The batch block combines (lets say 2) orders into a batch of the type Order ( advanced settings set to population of agents)
The service block pulls a truck from the resource poule and send the batch of orders to the truck agent using send(batch.unit)
The truck agent stores the order/orders(?) in a variable called "order"
Then, a moveTo function should deliver the order to the first destination
What would be the code to move to the first, second etc., destination?
Here is the conceptual piece you are probably not aware of, and that should help you move in the right direction:
you can have "for loops" as part of your process flows. Below, you see an example where an agent keeps driving to places until it has no more parcels.
Obviously, the details of the blocks depend on your model but in each, you can access the truck's orders if you have them in your Truck agent type (which is needed, obviously).
I am trying to connect different agent types by names. So, for example, I have a dataset where I have a list of patient names and their doctors name. I would first like to create two different populations of patients and doctors where each individual agent is assigned a name from the dataset. Then I need to create connections between the two different populations based on the corresponding connections in the data. Anyone know how to do this? Any help appreciated!

Let's assume your doctor and patient agent populations are created, and the patient having a parameter called doctorName, and the doctor having a parameter called name. You have to figure out how to do this based on where you get the info from. I will also assume that all doctor names are different.
the doctor will have a link to agents object (from the agent palette) called patientLink as a collection of links and bidirectional, but as a single link on the patient side (called doctorLink on the patient side).
now you can use the following function to connect them:
for(Patient p : patients){
Doctor doctor=findFirst(doctors,d->d.name.equals(p.doctorName));
p.doctorLink.connectTo(doctor);
}
You should use the "Agent Link" object. This does exactly what you need.
In your case, you will need to write some code looping across your data and setup the links accordingly. Check the example models using AgentLink objects to learn about it and read in the help, there is a lot of stuff on it.
Here are just a few quick thoughts on this that I hope are helpful in your process:
1) If you want to keep doctors and patients linked, you can craft an agent as a doctor-patient dyad--this could make a lot of sense depending on what your research question is; or
2) If one doctor handles more than one patient, you could also consider forming an agent that is actually a network-type arrangement with the doctor as the central node--again, this depends what your research question is and what your data looks like; or
3) If you want to link doctors with patients based on some rule, consider using a discrete event approach by using a "Match" function from the "Process Modeling Library" palette.

I want to take data from 2 databases and copy(coalesce) it into 1 using Data factory.
The issue is: It seems that multiple inputs is not allowed for copy activities.
So i resorted to having 2 different datasets which are exact copies but with a different name... and then putting 2 different activities into the 1 pipeline which use their specific output dataset.
It just seems odd and wrong to do it this way.
Can i have some help.
This is what my diagram currently looks like:
Is there no way of just copying data from 2 seperate databases (which have the same structure but different data) to the 1 database?
The short answer is yes. But you need to work within the constraints of how ADF handles this.
A couple of things to help...
You'll always need at least 2 activities to do this when using the copy type activity. Microsoft of course charges per activity execution in ADF, so they aren't going to allow you to take shortcuts having many inputs and output per single copy activity (single charge).
The approach you show above is ok and to pass the ADF validation as you've found you simply need to have the output datasets created separately and called different things. Even if they still refer to the same underlying target table etc. This is really only a problem for the copy activity. What you could do is land the data firstly into separate staging tables in the Azure target database just for the copy (1:1). Then have a third downstream activity that executes a stored procedure that does the union of tables. In this case you could have 2 inputs to 1 output in the activity if you want to have that level of control in ADF.
Like this:
Final point, if you don't want the activities to execute in parallel you could chain the datasets to enforce a fake dependency or add a simple 'delay' clause to one of the copy operations. A delay on an activity would be simpler than provisioning a time slice offset.
Hope this helps
Good afternoon to everyone,
I have a problem with the software AnyLogic. I have to do a program that is able to combine two agents (two different semifinished) to create one final agent (final product). The problem is that the two semifinished have different production time, so I need a function that is able to accept one agent (the first semifinished), than to wait for the second agent and at the end to generate one final agent from the previous two agents (semifinished). How it's possible to do this? I have already tried with the function "Combine" without any success.
You need to use the "Assember" object from the process library. Speciy how many agents of type A and B you need (1 each in your case). The assember will create a new agent type (you need to specify it) from the 2 incoming agents once it has got 1 of each.
Also check the help on the Assembler, you can do lots of fine-tuning with it.
cheers
