The objective of this book is to bring into accordance the two obviously completely contrary concepts of time and Petri nets. Introduced by C. A. Petri in [Pet62], Petri nets can be used to study concurrency in the sense of causal independence, but they do not directly deal with time; time is involved only implicitly through the causal relationships. However, the explicit indication of time is indispensable for a great variety of real problems. Even qualitative studies of strongly time-dependent systems are very inexact if time is included only implicitly through causality. The question arises, whether one should at all try to describe and analyze such systems using Petri nets and whether it is even possible.
