How to load and unload two pallets at same time?

Problem_two pallets at same time.fsmHello everyone!

In this model, trucks arrive at a warehouse and are unloaded. After unloading, they are loaded with other items and leave the system.

The problem is that my forklifts work with a capacity of up to two pallets at the same time, both for loading and unloading.

I developed a logic with subflow to represent the operations, but I couldn't do it with two pallets.

Hello @WillRS , i modified your model to represent the unloading of 2 pallets at the time from the truck. Same logic could apply to loading.

Ow, thanks! It's work.

Could you explain to me what creationRank does?

Another thing, related to animation, how can I move the presentation of the two pallets so that they are not overlapping?

The flowitems are stored in an array, so you need an index in the subflow tokens to reference them. For that, you can use Creationrank, which is a property that generates consecutive numbers for the tokens created in the subflow.

For the animation, maybe use a change visual activity with the option set location to place the pallets in the position you need them.
