How to assign multiple destinations for a Task Excecuter using Global Table?

Hello Flexsim answers group,

I would like to ask a question as an extension to my old question which I posted earlier. Check the lik 1 processor to multiple processors.

I made some changes to earlier model and replaced the human task executor with an AGV. I added more processors and used a global table to allocate pickup and drop-off destinations. A few pickup points have multiple drop-off destinations, whereas others only have one, according to my model. I noticed a problem with unloading when I was simulating the model, especially those pickup points with single destinations. I found that i was unable to conect global table data to unloading activity in process flow.

How to instruct a task executor so that it reads data from a global table and operates in accordance with defined pickup and dropoff destinations (sometimes multiple destinations).

Any advice or assistance would be much appreciated!

To split the items between the possible destinations, you need to know how many destinations there are. In the attached model I added an extra column to the "GT" table that stores this number ("NumDests").

(You could write some code that updates this column on every reset, based on how many non-null entries there are in columns 3+.)

With this number and the amount of loaded items, you can then calculate which "bracket" each item belongs to. In the attached model this is "DestIndex" label. That label can then be used to directly access the correct column.

I added a third destination to the first row to show that this will work more destinations as well.

@SaiKrsih . I made a little adjustment to your model. Replicate the Destination1 into the Destination2 column as well. For eg: The destination1 you assigned for Q6 was Q5. Just type Q5 in destination 2 as well.
