 Abstract: This paper briefly explains some basic concurrency issues that are present when modeling with classical place transition nets. Many users assume that certain Petri net structures are concurrent or concurrency free. However, it can be shown that concurrency does not depend only on the structure but also on the distribution of resources in the net. Some toy examples are given to show the different possibilities and concurrency is classified into (i) dependent and (ii) temporal (weak) concurrency. Some findings are presented.
