About Transportation

As the model works, the results satisfy my requirement,

I record ABC three queues' current number in GlobalTable1,

The "Flow" option in A, I select "Conditional Port", the following is condition,

current.num > 5 && getdatastat(STAT_MIN, gettablerows("GlobalTable1"), gettablenum("GlobalTable1", count, 3)) < 2

I let the queue which current number is bigger than 5 throws a product to the queue which current number is less than 2,

At the beginning, I let Source1's "Arrival Style" be "Inter-Arrival Time", this option can work correctly,

But when I set "Arrival Style" to "Arrival Sequence", and one arrival with quantity 10, this option can't work correctly, can somebody tell me why?

This seems a runtime problem. The items get the state to be releasing the queue. But releasing isn´t the same as exiting or entering another queue. The transfer isn´t finished. The send to port function evaluates on each item the conditional states in the model, there isn´t a change as long as the transfer isn´t complete.

give FlexSim the time to move the items. Create the items instead 10 at a time stamp, create each single item with a small time gap of 1/100 second.
