By this article I start publishing all interesting stuff I've made. Kind of portfolio.

Visual Petri Net Plus (VPNP)  was thesis of my diploma work at Technical University of Moldova(2000-2002). It is Petri Net designer, simulator and calculator. It has nice graphical engine that help to draw Petri net quite easy.

Theory of Petri Nets is intresting, you can find a lot of information on the net.

My work was to do graphical designer, save/load and simulation.

Tools used: Delphi 5.

Designer interface

Interface was inspired by standard Delphi interface.

#

Element property editor

Looks like standard delphi Object Inspector, but it is not. It is custom written.

Sample nets drawings

Simulation

This is most attractive part in this project.

Simulation control panel

Allows to add graphs to see progress during simulation.

Live simulation

It was recorded from real example. Flash plug-in required to view.

Downloads

Download executable and some sample to play with.

Source code is available with no support from my side, use on your own risk.
