How to make AGVs get mission at diff LFW points ?

Attached is a simplified AGV model.

AGVs use NextLookForWork Loop to get missions, that means every AGV has to traverse the LFW points one by one in the loop until getting a mission, thus, there will be a circumstance under which one LFW point generates missions much more frequently than others, as a result, the missions generated by some other LFW points may not be received by AGVs.

How to solve this kind of problem?

Any suggestion will be appreciated !!

You can use the LookForWork connection (not the NextLookForWork connection). If you connect multiple work points to a single point on the NextLookForWork loop using the LookForWork connection, the AGV will look at all the work at once. You can then modify the query in this activity:

For example, you could add an age field to the Local Partitioned List (the list the activity above pulls from), and then use a query like this:

ORDER BY age DESC

That way, the AGV will get the oldest item, rather than the item it encounters next on the NextLookForWork loop.
