Simulation Troubleshooting: Simulation is not working

(Copied from e-mail with Bizagi team to share with the community. Will keep this thread updated with results)

My team has been

evaluating Bizagi as a potential solution for our BPI initiative currently

underway at our company. We cannot, however, get the simulation to work,

despite scouring the feedback.bizagi.com site and redrafting, rechecking our

models numerous times.

We would greatly

appreciate your assistance in helping us understand why this is not working. I

have attached a very simple process, defined all the parameters, resources,

calendars etc. and still get the error message “The simulation has failed.

Please ensure your model is compliant to the BPMN 2.0 standard and that it is

supported.” The simulation has never worked on any of our models, not even this

very simple model.

Our Specs:

Windows 7 Ultimate

Service Pack 1

RAM: 8GB

Excel: v9.0

Other system

requirements are all fully met as confirmed by our IT team.

(Response from Support Team from e-mail)

In order to simulate without any

problem, please upgrade your current Bizagi Modeler 3.0.0.022 from: http://www.bizagi.com/en/products/bpm-suite/modeler#downloadmodeler

Then, apply the latest FIX from: https://bizagi.sharefile.com/d-s95f33e09a384e7f9

using the instruction file.

We would like to ask you if you could share your posts on the

Bizagi Process Modeler forum (on http://feedback.bizagi.com/en/),

where it can be viewed and treated by the Process Modeler community and its

experts.

Best Regards,

Support Team

Update 1:

  1. We already had v3.0.0.022 installed but we re-installed just the same.
  2. We also had already applied FIX 28BA26913 but we did it again after reinstalling.

We still have the same problem (no change at all). Every simulation fails with the error message:

"The simulation has failed. Please ensure that your model is compliant to the BPMN 2.0 standard and that it is supported by the Simulation Engine."

Any insight into what is going on here?

Dear Bizagi Modeler team,

As per my last comment, could you please reopen this topic? It is not solved as we still cannot use the modeler after trying the reinstall and applying the patch.

Grateful if you could jump back into the thread and let us know what else we may be able to try.

Many thanks

Hi Will,

I don't know it this is a solution for your problem, but the error you get happens to me when there is a consistency problem with some paramenter. For example, if you use Time Analysis, and use a Normal Distribution for Processing Time, the random number generator could generate a negative number, thats fine. BUT a time can't be a negative number. Then, it pops up the error you mention. If you change for a Truncated Normal Distribution, then works fine.

Because the random number generator is random, of course, some times the error appears, but some tiemes there is no a negative number, the errors doesn't appear.

Good luck.

Hi Edgardo,

Many thanks, appreciate your input and suggestion. I will try the truncated normal distribution and see if anything changes and will report back here.

Cheers,

Will

Dear Will,

If the recommendation of Edgardo did not work, please check the simulation considerations on this article: http://help.bizagi.com/processmodeler/en/index.html?simulation_in_bizagi.htm

If the problem continues, we require to analyse your BPM file. Please send us a copy of it to modeler@bizagi.com. This information will be treated as strictly confidential and the file will be deleted once it is no longer needed for support purposes.

We look forward to hearing from you

Hi Juan,

Thank you for your reply and for updating the status. I will be looking into the solution that Edgardo proposed and will get back to you on our progress.

Cheers,

Will

Hi Juan,

I have tried Edgardo's suggestion and applied truncated normal distribution to all tasks. There is no change, the process fails to simulate.

I have downloaded samples of process flows that your team has made available in other message threads and these all fail to simulate for us as well -- same message every time, at every simulation level: "The simulation has failed. Please ensure that your model is compliant to the BPMN 2.0 standard and that it is supported by the Simulation engine."

In addition, we have read through all the message threads about simulation and have tried other solutions offered by your team, including:

1. Reading through the entire simulation help section on the site

2. Installed (and reinstalling v3.0.0.022

3. Applied FIX 28BA26913

None of this had any effect on our very simple workflow we made for testing purposes. I will send this to your team via e-mail again and see if there is anything you can find.

Many thanks,

Will

Dear Will,

We received your BPM file and we were able to simulate it without any problem. Our team will write you to analyse why it does not work in your PC.

Hi Juan,

Many thanks for your quick reply. It is good to know that we have been building our models correctly at least! I look forward to hearing from your team and troubleshooting.

All the best,

Will
