Problem Concerning Customized multi-AGV and Zone

Hello,

I have encountered some problems regard of the process flow. The model works well if I only ask one of agvs to do load and unload. But if I trying to let the two agvs to work at the same time, it tirns out to be some problem.

1. The problem occur by the action of global table Row2 and Row3. I would like to ask why the two agvs will not load their independant goods?

2. When I was trying to use zone to set the maximum number, I was wondering how can I set the zone only allows the maximum number of 1 with different token.TE value to enter the zone?

The attached is the model I am trying.Thank you for any of your help and suggestions!

1. The lists you are using are shared between the two AGVs. For example, when the token of AMR1 pulls an item to unload, it pulls the one that is currently on AMR2.

You could partition the lists (at least the "on car" and "finish" list). The "on car" list would be partitioned by the AMR and the "finish" list by the queue the item is in. You can then an item from the correct partition to not mix the items between the two AMRs/stations.

2. Similarly to the lists in 1. you can also partition a zone and limit the content of each partition.
