I am using "moveto" to reach at destination caller Dryer. Dryer have "queue" and "delay".
Now when agent come it first go to Dryer and then go to "queue" and then wait for its turn to go to Dryer for "delay".
What should happen is agent move to the "queue", wait for its turn to go to Dryer. How I can achieve that?
My approach
1. MoveTo
2. Queue
3. Delay
what you should do is use a conveyor block instead of a moveTo + queue blocks like this:
The conveyor will act as a queue and everything will be ok
You will have to define the path for the conveyor and set the delay with capacity 1 and the location of the delay on the dryer
What I would do is put a Node with a radius 0 very close to the Node associated with the dryer and send the agents there.
See below each block where I associate it:
Good luck!

is there any easy way to detect that agent stopped on a roller conveyor because there are other agents ahead? I tried to use dynamic variable and conditional event but it is consuming too much performence. I don´t want to go for dynamically checking condition (with cyclic event) because I have some bad experience with it.
Thanks!
Try this:
Create a LinkedList<YourAgentType> agentsOnConveyor.
Whenever an agent enters the conveyor, call agentsOnConveyor.addLast(agent). When it leaves, call agentsOnConveyor.removeFirst(agent).
Now you have a linked representation of the agents on the conveyor.
Last, you use the "on stopped" field in the conveyor and pass the message "upstream" through the linked list, i.e. use a for-loop from the first to the last entry and send them a msg "conveyor stopped".
You may still need to check if the individual agent is moving itself or has also stopped, but it might put you on a working path
By seizeTransporter block my AGV seizes an agent called "Sitz" and transports it via Move by Transporter block to a Delay Block.
When AGV enters the delay block the transported agent "Sitz" is changing its cargo location to 0.
I tried to fix that issue with creating an parameter on main called p_assemblyHight with default value 1.0 and the following code in Actions section of the delay Block: agent.setHight(p_assemblyHight, METER);
Anyway this action will not execute.
What can I do so that my transported product (called "Sitz") stays on the agv and not dropping in delay block?
Check the two screenshots for better understanding.
Thank you a lot!
The setHeight method does not change the z-component, but the height of an agent presentation. Irrelevant for you.
You need to access your Sitz in the delay block and change its z-component.
In the Delay block call:
agent.setXYZ(agent.getX(), agent.getY(), 10);
The last argument is the Z component, adjust as needed. The first 2 just make sure the XY components are not changed
I have 2 storages (called storageA & storageB) and I want to move an agent (pallet) from one to the other via forklifts. I have set up the following.
A pallet is created at a node and is moved to storageA via 'store'. This part works fine. The pallet is then moved to storageB via 'store1' after a delay. This is when the following error occurs:
Exception during discrete event execution:
root.store1.seizeTrans.freeSpaceSendTo:
Path not found! {agent=2, source={level=level, pos=(1673.3333333333333, 3245.0, 0.0)}, target={level=level, pos=(1857.25, 3160.4845, 0.0)}}
It works if I replace 'store1' with a retrieve block and send it to a node first. However I would like to send the pallet directly to another storage rather than via another location. Is this possible?
Please let me know if I have not provided enough information.
Thanks
yeah unfortunately you can't do that as far as I know, the solution I use is the following, which is actually not a super robust solution... but has been ok in applications so far
Place a retrieve block between your delay and your store1
Use the agent you pick up as destination:
on the on seize action of the retrieve block do:agent.transporter=unit;
4.On the store1 block put the highest priority for the task
5. ON the store1 block use resource custom transporter choice: agent.transporter.equals(unit)
6. The dispatching policy should be nearest to the agent in store1, but doing all the above ensures that the resource continues doing the task no matter what... by only using the dispatch policy your model will work 99.999999% of the time... the problem occurs only if another task with higher priority occurs at the exact same time as the transporter is released in the retrieve block, which is rare, but can happen.
I had the same question today so I landed here. But luckily, only after the second step written above, the whole process needed did already work for my case. We can move an agent from one storage to another by simply set the destination of the 'retrieve' block to the coordinate of the agent and the move to independently instead of by fleets or resources. after that we put the 'store' block.
Destination is: (x,y,z)
X: agent.getX()
Y: agent.getY()
Z: agent.getZ()
after agents being retrieved to a specified coordinate, it seems that fleets do not comply paths in the network anymore
I am trying to force agents of a population to exchange messages in AnyLogic. I would like each time agent A sends a message to B the icon of the message to move from A to B. How can I implement this?
The code Emile sent you works to move an agent from one place to another one. I understand you don't want to move your two agents, but instead you want to move only a "message icon" from one to the other. For that you can create an agent (let's call it agent "Message"), create it and locate it in the agentA, and tell it (as Emile said) to move to agentB: messageAB.moveTo(agentB.getPosition()); this way you'll get the effect you want.
You could also:
use a timer to move from one place to another, or
use an event and change the position of the icon dinamically depending on how much time you have remaining on that event
use a source/delay/sink for the same as in point 2
There are basically two ways to move an agent:
Jump to agent B: Instantly appears near agent B
Move to agent A at a certain speed
For each one the code is respectively as follows:
agentA.jumpTo( agentB.getXYZ() );
agentA.moveTo( agentB );
Where agentA and agentB refer to the agents which you might call differently depending where you are in the model.
I am building a DES-ABM hybrid model in AnyLogic.
The agents go through the DES blocks, among which multiple Delay blocks.
How do I
access an agent which is in a Delay block
or peferrably
acces the specific agent which triggered the 'on enter' action of the delay block?
My ultimate goal is to open or close a valve object on the agent frame
So can I/ how do I
A. open or close the valve on the agent frame directly form the main/root frame (on which the Delay block is located)
or if that is not possible
B. send a message or trigger a statechart within the specific agent which will then open or close the valve from the agent's own frame?
I have tried to use the 'DelayBlockName'.agents() function, but this does not work and returns [] when I check it using traceln.
access an agent which is in a Delay block or peferrably
use the keyword agent. These keywords differ for different library blocks so best start learning about the lightbulb and how it can help, see here.
acces the specific agent which triggered the 'on enter' action of the delay block?
When you write agent. in the "On enter" block, every agent coming through will execute that code, so by definition, it is always the specific agent :)

this is something completely different to your original question and just... messy. Please limit questions to 1 topic so it is easy for us to answer :) (see this guide for more)
