Conformance Analysis

Haydee

My main research area is Process Mining, and I am trying to run the plugin ‘Replay a Log on Petri Net for Conformance Analysis’ on PromLite, but the all the results are full of zeros.
I did the pnml file with Wolfgang and loaded it with PromLite as you can look in the next image



I imported a csv file, converted in xes and used these files to run the plugin, at the moment when i do the 'Mapping Petrinet - Event Class of Log' the plugin correctly recognizes the information contained in two files, as you can see next



But in the final result I get nothing in any of the transformations or places.


Is there some issue that I am skipping?
Thank you in advance

Hi, did you try to press 'no' in the pop-up (which mentions something about model moves). If I recall correctly that works. You might also want to change the event classifier in the 2nd screenshot you shown, to 'Event name' classifier.

Hi, the only pop-up that ProMLite show are

In your course "INTRODUCTION TO PROCESS MINING WITH PROM" there is no example with that pop-up.
Thank you in advance

Hi Haydee,

Please read the first pop-up carefully: it mentions that the initial marking is empty. This means that there is no token in the first place, hence no enabled transition. Please use the 'create initial marking' plug-in to add an initial marking including the first (left most) place of your Petri net.

Hi, thank you very much for the remark, I am resolved this problem but the final results are still zero

Hi Haydee,

Do I understand correctly that you added the initial marking, but the replayer results stayed the same? Are you sure you selected the correct place to be the initial (and final) marking?
Sometimes closing ProM and then adding the markings in a new instance of ProM helps.

Hi, Thank you very much for the exchange, i got the expected results.
