Petri nets provide a formal framework for system modeling
and validation which has proven to be very reliable in
practice. This book presents variousnet models appropriate
for designing specific systems, where systems are understood
very generally as "organizational systems" in which
regulatedflows of objects and information are significant.
The models are interrelated in the sense that they have
common interpretation patterns: together they can be
understood as a method for specifying any given system or
any section of such a system to any given degree of
refinement. The simple and immediately understandable
principles of system modelling with nets makes it possible
to provide an illustrated description of this method without
going into the mathematics behind it. The text is based on
courses the author developed for project engineers and
project managers in the area of embedded computer systems.
