Such information can be used to discover other perspectives, check the conformance of models that are not pure control-flow models, and to extend models with additional information. For example, one could derive a social network based on the interaction patterns between individuals. 4 Analyzing an Example Log 17 Fig. ”) dividual x performed an activity that is causally followed by an activity performed by individual y, the stronger the relation between x and y is [104]. 7 illustrates the way in which a control-flow oriented model can be extended with the three other main perspectives mentioned in Sect.

Formally, for any p ∈ P and any M ∈ [N, M0 : M(p) ≤ k. The marked Petri net in Fig. 4(c) is 25-bounded because in none of the 7776 reachable mark- 38 • • • • 2 Process Modeling and Analysis ings there is a place with more than 25 tokens. It is not 24-bounded, because in the final marking place out contains 25 tokens. A marked Petri net is safe if and only if it is 1-bounded. The marked Petri net shown in Fig. 2 is safe because in each of the seven reachable markings there is no place holding multiple tokens.

TS is often referred to as the reachability graph of (N, M0 ). 3 shows the transition system generated from the labeled marked Petri net shown in Fig. 2. 2 Process Models 37 Fig. 4 Three Petri nets: (a) a Petri net with an infinite state space, (b) a Petri net with only one reachable marking, (c) a Petri net with 7776 reachable markings tokens. Note that S start = {[start]} is a singleton containing the initial marking of the Petri net. The Petri net does not explicitly define a set of final markings S end .
