These Transactions publish archival papers in the broad area of Petri
nets and other models of concurrency, ranging from theoretical work to
tool support and industrial applications. ToPNoC issues are published as
LNCS volumes, and hence are widely distributed and indexed. This Journal
has its own Editorial Board which selects papers based on a rigorous
two-stage refereeing process. ToPNoC contains: - Revised versions of a
selection of the best papers from workshops and tutorials at the annual
Petri net conferences - Special sections/issues within particular
subareas (similar to those published in the Advances in Petri Nets
series) - Other papers invited for publication in ToPNoC - Papers
submitted directly to ToPNoC by their authors The fifth volume of ToPNoC
contains revised versions of selected papers from workshops and
tutorials held in conjunction with the 31st International Conference on
Application and Theory of Petri Nets and Other Models of Concurrency, as
well as a contributed paper selected through the regular submission
track of ToPNoC. The 12 papers cover a diverse range of topics including
model checking and system verification, synthesis, foundational work on
specific classes of Petri nets, and innovative applications of Petri
nets and other models of concurrency. Thus, this volume gives a good
view of ongoing concurrent systems and Petri nets research.
