pDESy: Discrete Time-Event Simulation in Python

pDESy is a Python package for Discrete Time-Event Simulation (DES). It aims to be the fundamental high-level building block for practical, real-world engineering project management by using DES and other DES modeling tools. pDESy focuses on Discrete Time-Event Simulation and does not include visual modeling tools.

Install

Install the latest released version from the Python Package Index (PyPI):

pip install pDESy
# pip install git+ssh://git@github.com/pDESy/pDESy.git # INSTALL FROM GITHUB

Optional Dependencies

Visualization (matplotlib, plotly): If you want to use visualization features (Gantt charts, network diagrams), install with:

pip install pDESy[vis]

or install the visualization libraries separately (kaleido is required for static image export in plotly):

pip install matplotlib plotly networkx kaleido

Note

Starting from v0.8.0, visualization dependencies (matplotlib, plotly, kaleido, networkx) are optional to avoid mandatory dependency on kaleido, which requires Chrome for v1.0.0+. This keeps the core pDESy package lightweight for CI/CD and production environments.

Documentation

API documentation is available at: https://pDESy.github.io/pDESy/index.html

How to use pDESy?

Example code of pDESy is here .

If you want to implement more complex models for describing real engineering projects, you can create new models by inheriting the base models.

Background

pDESy is developed as part of the next-generation DES tool pDES.
