My simulation stops at event based gateway

Dear Jana,

You could check if your model has some elements which are not currently supported by the Simulation engine in Bizagi.This engine is provided by Lanner, our technological ally, and it will not currently simulate models having:

• Complex gateways.
• Transactional Sub-Processes.
• Gateways which not entirely define as converging or diverging (exclusively). Meaning, that a gateway should be either (convergent or divergent), but not both or none.
• Start events of the multiple start type.

Regards

it is event based gateway. I even tried making a new model just to test it and it failed.

Is there a workaround?

Regards

Dear Jana,

You can include gateways, but no complex gateways. Be sure in this point: Gateways which not entirely define as converging or diverging (exclusively). Meaning, that a gateway should be either (convergent or divergent), but not both or none.

You can share your model in order to analyze it.

Regards

Dear Juan.

Please return to my original question:

1. event based gateway didn't work
2. to test the gate I created new diagram and copied textbook example. I only used message and timer events instead of the two events used in this example
3. the simulation crashed even on textbook event based gate

So my questions are:

1. Is the event based gate still not working?
2. Is there a workaround that would be less ugly than substituting events by tasks with description of the event?

Regards

Dear Juan.

I played around and it stopped exploding. However the event based gate still doesn't let anything through.

Is there something that can be done with it?

Regards

Dear Jana,

Sorry, I was confused with complex gateway and event based gateway. Please check the following considerations to take into account:

•The following BPMN elements are not supported by the simulation engine:

• Multiple events: Start, Intermediate and End.
• Complex gateways.
• Event based gateways followed by none intermediate events or tasks.
• Multiple instance tasks.
• Multiple instance Sub-processes.

•The following diagrams are not supported by the simulation engine:

• BPMN Choreography diagrams.
• BPMN Conversation diagrams.
• Transactional process.
• Ad Hoc process.

Regards

Hi Jana,

From what I can see, it seems like there is nothing throwing an event to your process (hence nothing to catch, hence stuck waiting).

Have you tried using a second pool to enable that communication? See my example (attached file) using messages sent and received between 2 pools.

Haven't played with the conditional event, but the principle should be pretty similar.

Please don't hesitate to contact me if you have any questions/comments.

There is a different aswer to Jane's question (see my Comment earlier today), as this situation is not one of the excluded cases mentioned in the documentation (since we have an Event-gateway that is not followed by a None intermediate event or task).

I'll be glad to elaborate, if anybody is interested.

Thanks,

Razvan:-)
