Preface by the PNSE’2020 Organisers



These are the proceedings of the International Workshop on Petri Nets
and Software Engineering (PNSE’2020) to be held at June 24, 2020. The
workshop is co-located with 41st International Conference on Application
and Theory of Petri Nets and Concurrency (PETRI NETS 2020) in Paris,
France.
    The workshop emphasizes on the impact of software engineering in
general and its development based on Petri nets. Therefore we have espe-
cially invited contributions that work on subjects that could be relevant
for Petri nets, their application, supporting tools, etc. Results on other
formalisms or semi-formal techniques are highly welcome. More informa-
tion about the workshop can be found at:

    But then, during the organisation phase in early 2020, covid-19 took
over. The organisers of PNSE decided to finalise the reviewing process as
normal as possible. However, the workshop itself is now organised as a
virtual meeting of the main conference, which is virtual as well.
    Overall we received 24 contributions for these proceedings. Each paper
was reviewed by at least three referees. During the reviewing process the
program comittee selected 13 contributions for publication. The program
now consists of six papers that are chosen for a long and seven for a short
presentation. The proceedings also contains the extended abstracts for
the poster contributions.
    The international program committee of PNSE20 was supported by
the valued work of Artur Niewiadomski, Manuela Dalibor, Teofil Sidoruk,
Louis Wachtmeister, and Jörg Christian Kirchhof as additional reviewers.
Their valuable work is highly appreciated.
    Furthermore, we would like to thank our colleagues in the local orga-
nization team for their support – especially for serving a wonderful virtual
coffee in the breaks.
