Cascade tokens producing and consuming

edited April 2015 in Process Mining

In my Petri-Net model there are AND structures and when applying conformance checking using the model, some cascade tokens producing and consuming are performed, which decreases fitness score severely. (Shown in the attached figure) Is it more reasonable to only produce once until the produced ones cannot fire all the transitions next to the adjacent transition instead of consuming the tokens right after finishing the adjacent transition?

    Dear zmlzeze,

    I think I understand your problem: you suggest to have a mismatch earlier in the process, such that the many activities in parallel would be executed correctly, and the overall fitness would be higher.

    This is exactly why the alignments based conformance checking has been implemented, which takes these considerations into account. See also my reply to your other question here on the ProM forum.
