Hi.
I have a model with 2 item types wich arrive to one queue (Pulmon CD). Then, these flow items are moved by 3 transporter (using 1 dispatcher) to 2 racks depending on the ItemType. Currently, it is working, but the 3 transporter are moving any item (dispatcher pass to first available).
I want that 2 out of 3 transporter move the itemtype 1 to rack1 and the 3rd transporter moves de itemtype 2 to rack 2.
Rather than use the dispatcher for all 3 transporters, I would use the dispatcher only to coordinate for the transporters that are taking the Type 1 flowitems to the one rack, and then make a center connection from the queue to the third transporter directly and use this option under the queue's Use Transport property:
This way transporter 3 is only requested for item type 2, and item type 1 can request either traporter 1 or 2. See attached model.
The dispatcher must get the Type of the transported item out of the tasksequence, which he passes to the transpoirters. Then you can easily transfer the Tasksequence to one of the output ports. But it gets difficult to achive this, if you want to transfer one Tasksequence Type to two available transporters. But if you insert another Dispatcher behind the first, then this dispatcher organize which of both assigned transporters will get the Tasksequence. The next source code picture does this for the Pass To function.
Instead of using a dispatcher you can achieve the same with a global Tasksequence List. The Queue pushes the Tasksequences onto a global Tasksequence List and the Transporters pull an available transport taskseqeunce from the List. If there isn't a Transport Tasksequence available a bachorder is created. The List contains a field that extracts the item of the Tasksequence similar to the source code above.
The Transporters pull in the OnResource Available trigger the Tasksequence which item Type matches with its duty.
The attached file demonstrates both approaches. Transfer_ts_by_item_type.fsm
