petri-net

Petri-Net v0.2.1

A simple library for modelling and executing Petri Nets.

Features

• Representation of simple Nets using token counters
• Typescript implementation
• OO paradigm
• Emit Events when Transitions are fired

Roadmap

• Weighted Arcs
• Adopt functional paradigm/immutable data
• Persist Nets and state to storage backend
• Extensions such as Coloured, Timed and Hierarchical Nets
• Stepwise replay and analysis of previous executions

Usage

var petri = require('petri-net'),
    _ = require('lodash');
 
var p1 = new petri.Place('p1'),
    p2 = new petri.Place('p2'),
    p3 = new petri.Place('p3'),
 
    t1 = new petri.Transition('t1', [p1], [p2, p3]),
 
    net = new petri.Net(p1);
 
net.ingest(10);
t1.on('fire', function() {
    console.log('t1 fired');
});
 
_.times(5, function() {
    console.log(net.describe());
    console.log('----');
    net.execute();
});
