Quartz - A Crystal Modeling & Simulation Framework

CI Status Build Status

Quartz is a Crystal library for defining models and constructing discrete event simulations.

The following features are supported:

  • Hierarchical models, through the coupling of sub-models via their input/output ports.
  • Discrete-event and discrete-time models.
  • Dynamic structure models.
  • A precise representation of the simulated time.
  • Heterogeneous models, e.g. coupling discrete-event and discrete-time models.
  • Model and / or ports observers.
  • Simulation hooks.





Crystal applications and libraries are expected to have a shard.yml file at their root. Create a shard.yml file in your project's folder (or add to it) with the following contents:

    github: RomainFranceschini/quartz

Then, resolve dependencies with shards (Crystal dependency manager) to install Quartz as a dependency of your project:

$ shards install


See the examples folder.

Underlying theory

Quartz is based on the PDEVS (Parallel Discrete EVent System Specification) formalism and some of its extensions (DTSS, DSDE, multiPDEVS).

This project is developed by a research group at University of Corsica.
