How to assign pallets to as per availability?

Developed model as pallets come in and advance to combiners whichever is available.

1.Whenever combiner2 is available pallets advance and process for 349 secs

2.Pallets advance at combiner2 will not wait at combiner1

3.Pallets process at combiner1 for 87 secs

Decision Point Simulation_V1.fsm

Unable to map this process flow as pallets are advancing while combiner1 is in process please can you help me with this issue as soon as possible.


Please find the attachment of model.

Thanks in advance.

I added the combiners to the process flow as resources. When a pallet arrives at the exit transfer of the first conveyor, a token is created by the event-triggered source. This token then tries to acquire one of the combiners. Depending on which one it acquires, the pallet is moved either into Combiner1 or to the next conveyor. The token will always prefer the second combiner due to the default query in the combiner resource. Note that the exit transfer is set to 'Do Not Release Item', so pallets are only moved to the next station by the process flow.

Depending on the acquired combiner, the label 'sendTo' is created on the pallet and set to either 1 or 2. This then controls where the pallet is send by the exit transfer of the second conveyor.

In either case the token then waits until the respective pallet was processed on the combiner and releases the combiner again afterwards.

I wasn't sure if pallets could skip the first combiner while it was active, so here is a second version where all pallets first have to acquire the first combiner. If the second one is available it will still skip the first and immediately release it again.
