Conversion of a heuristic net to a petri net

Dear all,

I have some problems with converting a heuristic net to a petri net. The heuristic net is very simple, but when converting it to a petri net (in ProM 6.1), 5 out of 6 invisible activities are included which are not necessary. Is there a way to solve this?? Or is someone familiar with this problem.

Thank you,

Jo

    I forgot to include the heuristic net and petri net. Here they are...

    Hi Jo,

    This is normal behaviour and I think this is caused by the 'default' way a heuristics net is converted to a Petri Net. By always including silent transitions the conversion also works for other cases where more activities are split/joined.

    These silent transitions can be removed using the Murata rules. This is implemented in the plug-in called "Reduce silent Transitions".

    Please let me know if this did the trick!

    Dear Joos,

    it removes 5 of the 6 silent transitions, but the one that I want to keep is also removed and one that I want to removed, stays. Is there a way to solve this, since you cannot change the settings of the 'reduce silent transitions' plug-in. Otherwise I need to create a petri net manually, and I want to avoid this option.


    Thank you in advance,

    Jo
