Petri net editing

Mousavi
edited June 2011 in ProM 6












Hi friends,
I use ProM6 as a developer.I want to make a part of a petri net that it is like picture that I attached it .How can I implement this? How can I implement
non-observable tasks (AND-split and AND-join) ?
with best regards

  • Hi Mousavi, 

    Do you want to edit the Petri net outside of ProM or within the code? For manual Petri net creation, I can recommend the Yasper petri net modeler, which works well together with ProM (see http://www.yasper.org/). Yasper exports Petri nets as PNML files that can be read by ProM. 

    But I am not sure whether this helps in your case. 

    Good luck, 
    Anne
  • Hi Anne,
    Thank you for your help ,I want to edit the Petri net within the code,and exactly I need to edit a apart of the Petri net like the picture that I attached it .I mean that I need to use  
    non-observable tasks (AND-split and AND-join) in the model, how was implemented they in ProM6 ?how can I use them ?

    cheer,

  • Hi Mousavi,

    Transitions have a public function 'setInvisible' to set the (in)visibility. I think that you are looking for this option?

  • Hi Joos Buijs,
    Does it mean that If I want to add a AND-split node like that one in the picture,I should add a transition in a suitable place in model and after that I should set that invisible?
  • If you need a 'dedicated' AND split place then yes, add a transition, mark it invisible and connect it to the places.
    You can of course use an existing transitions (/event/activity) to form the AND-split. Say, if you have A followed by both B and C in parallel then A could also be the AND-split.

    Let me know if this answers your question :)

  • Dear Joos Buijs,
    I know that when A followed by both B and C in parallel then A could also be the AND-split,did you see the Petri net that I attached? I want to coding a situation like that model, I think that I can do it with that option that you said . is it true ? :)

  • Yes, you can indeed implement this by adding a dedicated AND-split and AND-join transition and marking them invisible.

    I was just making sure you didn't unnecessarily add dedicated routing transitions when there is no direct need for :)

    Let me know if you succeed in implementing this in ProM 6!

  • only another one question :),  Is dedicated AND-split and AND-join transition an special Transition?
    or only I should add a transition and set it as a invisible transition ?
  • It is no special transition, it is just that the sole purpose of this transition is to function as an AND-join/split and does not 'implement' an activity that is executed by a user/system.
