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 9th volume of ToPNoC contains revised and extended versions of a selection of the best
workshop papers presented at the 34th International Conference on Application and Theory of
Petri Nets and Concurrency (Petri Nets 2013) and the 13th International Conference on
Application of Concurrency to System Design (ACSD 2013). It also contains one paper submitted
directly to ToPNoC. The 8 papers cover a diverse range of topics including model checking and
system verification refinement and synthesis foundational work on specific classes of Petri
nets and innovative applications of Petri nets and other models of concurrency. Application
areas covered in this volume are: biological systems communication protocols business
processes distributed systems and multi-agent systems. Thus this volume gives a good view of
ongoing concurrent systems and Petri nets research.
