Petri Net

• From Wikipedia, the free encyclopedia online
• A Petri net (also known as a place/transition net
  or P/T net) is one of several mathematical
  representations of discrete distributed systems.
  As a modeling language, it graphically depicts
  the structure of a distributed system as a
  directed bipartite graph with annotations. As
  such, a Petri net has place nodes, transition
  nodes, and directed arcs connecting places with
  transitions. Petri nets were invented in 1962 by
  Carl Adam Petri in his PhD thesis.
• At any one time during a Petri net's execution,
  each place can hold zero or more tokens. Unlike
  more traditional data processing systems that can
  process only a single stream of incoming tokens,
  Petri net transitions can consume tokens from
  multiple input places, act on them, and output
  tokens to multiple output places. Transition can
  only act on the tokens if the required number of
  tokens appear in every one of its input places.
• Transitions act on input tokens by a process
  known as firing. When a transition fires, it
  consumes the tokens from its input places,
  performs some processing task, and places a
  specified number of tokens into each of its
  output places. It does this atomically, namely in
  one single non-preemptible step. Since firing is
  non-deterministic, Petri nets are well suited for
  modeling concurrent behavior of distributed
  systems.

Petri nets
Nick Chapman, Imperial College, London,
1997 Petri nets, or place-transition nets, are
classical models of concurrency, non-determinism,
and control flow, first proposed by Carl Adam
Petri in 1962. Petri nets are bipartite graphs
and provide an elegant and mathematically
rigorous modelling framework for discrete event
dynamically systems. Petri net models have
emerged as a very promising modelling tool for
systems that exhibit concurrency, synchronisation
and randomness. The use of stochastic Petri nets
has become particularly important in the
modelling of automated manufacturing systems.

Search Zhou and petri net He has 77 articles.
12
Note Zhous most cited articles are from before
2000.
13
Most of Zhous articles after 2000 are still
being cited. He is current.
14
Over 7703 petri net articles have been published
and indxed in Scopus.
15
Note that one article has 1003 citations and the
sond highest is 193.
16
Tadao is tied with Zhou for largest number of
petri net articles. Tadao has the most cited
article.
17
Can we compare Tadao with Zhou? Actually if we
look at alternate author names Zhou has more.
18
Can we compare Tadao with Zhou?
19
Head to head Zhou has five of the top seven cited
artices between the two (i.e. Tadao).
20
When you compare a sample year of articles,1992,
Zhou has far more articles and citations than
Tadao.
21

22
Zhou has the 13th most cited petri net article of
all authors.

Who are potential current competitors and
collaborators?
26
(No Transcript)
27
Lin from China, for instance, is a likely current
and future competitor and/or collaborators.

Limit petri net search to 2000 to 2003
30
Rank in cited by order
Note new authors now most published
31
Further limit results to 10 authors with most
publications from 2000-2004
32
Conclusion M C Zhou is still publishing and
getting sited among top ten authors.
33
I searched for all petri articles from 2000
through 2004. There were 2611.
34
Except for Zhou the top three in published
articles changed.
35
Note Zhou now has the second highest cited
article again.
36
So how can might compare the five authors
(2000-2004) with the most articles?
37
I limited the search to those five authors
(2000-2004) with the most articles? 119 in
total.
38
I then ranked the 119 articles by cited by.
39
I then ranked the 119 articles by cited by.
40
I then selected the top ten cited by articles of
which Zhou had four.
41
I then did a citation analysis of these ten
articles. Zhou has 20 citations for a 2004
article, far above the others.
42
Next I went back to all petri articles 2000-2004
looking for the 10 most cited by articles from
any authors. Zhou had 2 of the articles.
43
Next I did a citation analysis of the 10 most
cited by articles from any authors. Zhou had 2
of the articles.
44
Note Zhou had the only top 10 most cited by
article since 2001.
45
If I am looking for current competitors and
potential collaborators this is the group. Most
cited by authors in 5 years.
46
Here are the publications we need in order to
keep up with petri net authors.
