How can i make the task executer carry more items?
Accepted solution
Here's your model with some changes so that the task executors will carry 100 boxes at a time:
The way I did this was through a few changes to your Process Flow. First, I added a "Batch" activity to your Process Flow so that each Task Executor would take a batch of 100 items.
Here, 100 tokens are converted into 1 token with an array of items named "boxes". This is useful so that every 100 tokens will only need to acquire one AGV resource.
Next, I edited your load and unload activities so that 100 items would be loaded or unloaded at a time:
Here, a subflow is started that includes 100 child tokens, one for each box. I've given each token a label called "Index" to identify which box in the array the token corresponds to.
Finally, in the load and unload subflows, I set it up so that each child token would cause it's corresponding box in the array to be loaded:
This causes 100 boxes to be loaded onto an AGV. I used a similar subflow for unloading.
I also made a few other changes. I removed a "wait for processor to finish" activity since it was never firing and I made it so that it simply released the processors after the AGVs are done unloading. I also changed the capacity of the processors to 100 so that they could accept all of the items at once, but you can change that back if you want them to process one item at a time.
If you would like to change how fast the boxes are loaded/unloaded onto the AGVs, make sure to change the load/unload time in the AGV properties:
I hope this helps!
This can be done pretty easily by making your processors into separate resources:
This works by using a Max Wait Timer for acquiring the Chipera that tells it to acquire the Logyard instead if the Chipera is busy:
Here the Max Wait Timer fires after 0 seconds if Chipera is unavailable and sends the token to Destination 2 (Acquire Logyard).
Note that with your current setup, it's impossible for the AGV to go to Logyard if Chipera is busy since Chipera is in the way. Here's another modified model I made with some changes to the network so that the AGVs can reach both processors: simulacionbaseanswer2.fsm

Anyway, what you are asking for is pretty easy. Under the "Custom Code" Process Flow activity, there are lots of options like closing and opening input ports for fixed resources:
I used a similar activity to open the input after each AGV is loaded.
Here's the model with this addition: simulacionbaseanswer3.fsm
I noticed that your process time on Chipera is 0.01 per hour:
That means it will take 100 hours to process one item. Are you sure that's what you want?
The problem you are facing is that your Process Flow is currently set up so that the processors are only considered busy if there is an AGV unloading there, not if the processor is currently processing. This would not be a problem, except you currently have the AGVs unloading very quickly and the processor processing very slowly, so that the processor is still processing by the time another AGV arrives there.
Part of the problem is that your AGVs are unloading all of their items onto Chipera before Chipera can finish processing even the first item. I know you set the maximum content of your processors to 1, but that does not stop Process Flow from unloading items when Chipera is already full. The result is that Chipera never becomes unavailable; by the time an AGV reaches Chipera, the previous one has finished unloading all of its items.
There are 2 ways we can fix your model then:
1. Have the unload time of the AGVs be slower than or equal to the process time on the processor. This would make it so that by the time the AGV is unloaded, the processor is about done processing too. This is how your model was before.
2. Reconfigure the Process Flow so that a processor becomes available once it is done processing all of the items unloaded onto it.
What works best for you?
