Tokens can be integers, floats,
strings …
Petri Net with Variables

Variables cannot be reassigned
during one transition firing
Timed Petri Net
We can Calculate GCD
Petri Net hooked with Java Statements
Send a Msg to SISServer
Petri Net to Java Class File

Possible Project



Implement an interface for user to
specify SIS messages
Hook the interface into ReNeW’s
implementation of Petri Nets
Then we can use ReNeW’s Petri Net
model to design Components of the
SIS System, with little effort it can
turn into real code.
My Term Project


Current SIS System is limited under
Windows Platform because of
prjRemote
My term project is to rewrite the
prjRemote part of the SIS System
using Java
Possible Improvements

First, the Java version of the
prjRemote will include messenger
within it, thus if we want to load a
batch of msgs, we don't need to
start a messenger component
separately.
Possible Improvements


Second, I would like to modify the
way we edit msgs, I would like to
remove the "Add Key","Delete
Key"... buttons. Instead, users can
edit on the msg pane directly.
Third, I would like to add an option
for the refresh rate of the right
pane(Msgs received by the
SISServer).
The End
