Tool Features

Petri Nets Supported (see also help on terminology)

High-level Petri Nets
Place/Transition Nets
Petri Nets with Time

Components (see also help on terminology)

Graphical Editor
Fast Simulation

Environments

MS DOS

Tool Description

Graphical editor of Place/Transition nets. Work on more networks simultaneously. Disk Save/Load. Various options like color, size, line styles, etc. Simulation in various modes including:

user/automatic selection from more enabled transitions,
fast/step modes, saving status to RAM (breakpoints).

User procedures in Pascal modify the net behavior and can generate (possibly random) duration of firing. So Time and High level nets are also supported. User code can add any user status data.This supports generation of Discrete Simulation Models. Support for simulation of Queueing Networks in the form of icons and transparent statistics.

Other Remarks

MS DOS based tool for education that can be started from Windows practically on any PC. Supports creation of Discrete Simulation Models in Pascal with simplicity typical for Simulation languages. Timing and synchronization is solved by the Time net, the rest by user added routines activated by events in the net (starting/finishing firing). Includes several units with objects supporting typical simulation tasks like:

generation of generally distributed random numbers,
automatic collection and computation of statistical data,
work with linked lists (queues) in Simula's Simset way.
