Problem with Networknode

Hello. I have created a model, but i have a problem with the networknode.I have created a network node(with "A" connections),but i don't know how to make the operators to travel through it.Please help me.

We recommend you go through the tutorial section of the manual.

In lesson 3's step-by-step section you'll see it explains that you need to connect a transporter (or operator in your case) to the network using the 'A' key.

The operators are flowitems coming from a source.I can't connect all of them to the network.

Hello vasiliki,

Take a look at the flownodes, they are used for flowitems in stead of network nodes.

Thank you.And how can i make the operators follow different random paths?

If you still want the operator flowitems to use a network, try using the 'taskexecuterflowitem' and choose the corresponding transportdispatcher picklist item under the flow page/tab.

If your destinations are connected via network nodes to the source, you can just return uniform(1,nrop(current),<stream>) in the sendtoport trigger of the flow page/tab. They will then use the same route for each destination unless you return a non zero from arrivaltrigger of a given network node - indicating which output path to go down.

If you use flownodes you can return a random port as above in the sendtoport trigger of the flownode's flow page/tab - but with that technique you can't control where they end up as easily.

I have done what you told me, using network node, but everytime an operator comes to a specific node, it sais:a traveler's requested destination is not reachable from the network. I rechecked my connections, but i don't see a problem.Furthermore, i didn't find the corresponding transportdispatcher under the flow page/tab, that you told me to choose.

I don't understand how your operators are using the network nodes if you didn't find the correct transport dispatcher pick item.

Attached is a quick model so you can check the settings I used.

I can' t open the file you sent me. Operators coming from a source, go to a source and then i want to move them through the network. I don't see a flow tab page under the task executer flow item.

The flow tab is on the source. Where it says 'Request Transport From' you select 'TaskExecuter as FlowItem'. The Source should be connected to the Network you want it to use, as should the destination(s).
