In the rackStore block, functionRack determines where the agent is stored (which can be one of three PalletRacks).
However in the rackPick block , I do not know how to specify the "Pallet rack / Rack system" field, and my search of the examples/handbook/other questions and guessing has been unsuccessful.
If you could help me out, I would be very grateful.
Thanks in advance

Put RackSystem block at Main, select all the pallet racks in the block properties. Then, go to RackPick properties, specify the RackSystem block. There are couple of example model: Wholesale Warehouse and Distribution Center, find them in Help - Example Models.

Using previous pick-up blocks, i have an container agent with two different agent types inside (Myagent and Myagent1). I want to insert two different drop-off blocks,the first for Myagent and the second for Myagent1. the problem is which element type i should choose for the drop-off block. For example, if i chose Myagent, it would give me error because of Myagent1:
If i chose Agent then:
Both the agent have a parameter named cc.
(I read other answers on the forum like Drop-off specific custom agents using drop-off block in anylogic, but i still have this error).
thanks for the help.
The best option here is to create a parent agent type that has 'cc' property and have the two types of agents inherit from it as described here. Also as a side note, you should probably take care to name the agents and properties with something meaningful as it will help to understand the model and explain it should you need to ask for help in the future.
I am trying to simulate a manufacturing assembly process, where material items are processed following an unique line. In the quality control stations, when a failure is detected, the object is sent to the repair area (by a truckpallet) and, when it is repaired, the same resource takes it and puts it at the start of the line. Until this point, I already programmed it.
The problem is the following: when it is a repaired object, is has to follow the same conveyor but with no stops in the stations. The object must enter a station and leave it, with no delays (as the works related with the stations have already been made).
I thought the best would be to consider the difference (repaired vs. not repaired) in the Agent, but then I can't work with it in the Main agent... I have also tried alternative solutions, for example defining variables in each station 1 and consider that in the stations delays and in the following station:
triangular( 109.1*delay_bec, delaytime_bec*delay_bec, 307.6*delay_bec)
Actions - in finished process:
if(delay_bec==0){
delay_headers=0;
delay_bec=1;}
But nothing worked... Any help?

This is actually the correct approach. You need to create a custom agent type, give in a boolean variable isRepaired (or similar) and then in the delay you can dynamically adjust the duration using that characteristic:
agent.isRepaired ? 0. : 100
This will delay normal agents by 100 time units and repaired agents not at all.
Obviously, you must make sure that the agents flowing through the flow blocks are of your custom agent type (see the help how to do that)
I'm facing an issue with the project I'm developing using Anylogic.
I would like to have a rack store block and a rack pick block to select a pallet rack programmatically, choosing it from an array list.
In particular, rack store is working in this way:
rack store block
The rack pick block gives me an error, saying that the first pallet rack does not contain the agent, even though, by debugging, it says that that pallet rack has no free space and moreover the agents in it are of the correct type and the agent to be picked seems to be correctly positioned in the pallet rack.
The rack pick block is the following: rack pick block
The info I was talking about the item are visible here and I printed them with the following piece of code:
traceln(palletRackListKuka.get(0).getByIndex(0).agentInfo());
traceln("class is " + palletRackListKuka.get(0).randomAgent().getClass());
traceln("has space is " + palletRackListKuka.get(0).hasSpace());
How can I solve this? Please ask for further details in case I was not clear enough.
The way RackStore and RackPick work is that the agent flowing through the blocks is the one stored and picked.
Thus your error is likely because the pallet rack you choose (programmatically) in your RackPick block is not the same pallet rack you stored that agent in when it passed through the RackStore block earlier. Your console statements just show that the pallet rack has some agents of the required type, not the agent that is flowing through the RackPick block.
You can just add the pallet rack you stored the agent in as an extra field (variable) inside it, which you then reference when picking it.
Edit: To do that, you are already providing an expression for the pallet rack to store in, so instead make that a function call to a function you create (returning a type PalletRack) which selects the pallet rack and stores it in a type PalletRack variable inside your IndustrialContainer agent.
If you want 'decoupled' picking (i.e., what to pick is determined externally in some way) that is something different where you have to have some mechanism to then
choose which specific agent you want to pick (say out of 1000 instances of the same product) which will typically relate to your 'storage/retrieval policy';
'inject' that agent into a RackPick block to pick it (e.g., via an Enter block).
See the Distribution Center example model for a version of this.
I'm developing a project with Anylogic and I have an AGV with a Kuka cobot on top of it (a sort of mechanical arm used to pick item from a shelf, in this case) which should pick some items from a rack store. I would like the cobot to pick more than one single item at once.
The blocks I already put are shown in the picture and I thought that specifying "seize whole set at once" in the rackPick block would have helped but it did not.
Could you help me, please?
Thank you in advance.
The RackPick logic is agent-centric, i.e. the items in the rack are the active entities. They, essentially "pick themselves", optionally using your robot as a help.
So if you want your robot to pick several, it is best to batch your agents together before putting them into a rack (using Batch) and then let your robot pick that batch agent. You can unbatch into the original agents afterwards.
PS: That "seize whole set at once" option is again from the agent perspective: if it would need several resources to be picked, then this option would have an effect. In your case, with only needing 1 robot, it is meaningless
I am trying to develop a model that essentially shows the movement of material in the warehouse.
I want the rackstore block to move multiple boxes at a time in the rack using crane. In the current model, crane takes one box at a time, stores it in the rack and comes back to take next box.
Not sure if RackStore supports that, but as always, you can find a solution in AnyLogic.
One simple fix: bundle your packages together into 1 agent using the batch object. Then, they stay together until being taken out by the crane at the end (via RackPick) and you can un-batch them to their original agents. Have a look at some example models using batching.
cheers
Depending on the details of your model, one option is to use batch as Benjamin stated, but I think I feel the pickup dropoff blocks would work better because with the dropoff you can drop the boxes one by one, while the batch forces you to separate all the boxes at once...
So with the rackstore you can't do this, but if you use the pickup and then dropoff, you will have to store somewhere in your model what rack positions are free though, because when you move the crane you will have to choose the rack position yourself, while the rackstore does it automatically...
Nevertheless, the batch may also work... it depends on the details of your model
