Workflow model analysis --- polymeric model
1) M I-polymer only When the M item is over, the A activity enabled2) n item aggregation 1 <= n <= m, in fact, a discriminator, after the N item is completed, the condition is satisfied, A activity Enabled3) Single aggregate Any event end, A activities enabled
There is a problem with N items and individual polymeric: A activity can be enabled? According to the answer to this question, the aggregation model can continue to classify.
Basically all of the workflow standards support M item aggregation and single polymerization, and N items are aggregated, and each standard support is different. The XPDL standard does not support N item polymerization.
