Max Capacity Adversely Affecting AGV Behavior?

 

I am attempting to simulate a group of AGVs feeding a line.

The video shows 2 different scenarios of a facility where 4 AGVs are bringing parts (1 each) to 4 identical parallel stations. In the first scenario the leading AGV has a capacity of 5 parts. In the second scenario the leading AGV has a capacity of 4 parts. Everything else is identical between runs. In both runs all other AGVs have a capacity of 4 parts.

When my capacity of an AGV is less than or equal to the number of destinations for parts in it's Route Group Definition it travels to all of the locations.

When the capacity is greater than the number of destinations for parts in it's Route Group Definition the AGV visits one station and attempts to unload all of it's parts.
