# salabim — salabim - discrete event simulation in Python

License: permissive · Maintenance: active · Downloads: 101.8K/mo

## What it is and what it does

Salabim is a discrete event simulation framework designed for modeling systems found in logistics, manufacturing, healthcare, and network analysis. It provides an object-oriented API with components, queues, resources, stores, and state tracking, allowing you to describe processes intuitively without yield statements. The library includes built-in data collection via monitors, 2D and 3D animation capabilities, tracing for debugging, and statistical sampling tools.

The package is cross-platform (Windows, macOS, Linux, iOS/iPadOS) and has minimal dependencies when animation is disabled. It follows a well-established process description method and is actively maintained with comprehensive documentation. The core developer provides direct support and consulting services.

Use it for:

- Model production facility workflows, material handling, and resource allocation to optimize throughput and identify bottlenecks.
- Simulate airport operations, hospital patient flows, or warehouse logistics to evaluate system designs before implementation.
- Analyze computer network behavior and packet routing under various load conditions.
- Create animated visualizations of simulations for stakeholder presentations or educational demonstrations.
- Collect and analyze statistical data from repeated simulation runs to support decision-making.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Salabim is a Python library for discrete event simulation (DES) that models systems with components, queues, resources, and stores, and provides 2D/3D animation and data collection without requiring yield statements for process control.

Yes. Salabim is a mature, actively maintained library with zero known vulnerabilities, low install friction, and permissive licensing. It is well-suited for anyone building discrete event simulations in Python, particularly those who prefer intuitive process description over yield-based coroutines. The built-in animation and data collection features add significant value for modeling and analysis workflows.

## Install

pip install salabim
uv add salabim
poetry add salabim

## Installing salabim

Before you install: Low install friction with no runtime dependencies; wheel-only distribution. Package is actively maintained with recent releases and a stable production status.

License in practice: MIT license is permissive, allowing commercial and private use with minimal restrictions; you may use, modify, and distribute salabim freely provided you include the license notice.

Quickstart:

pip install salabim

import salabim as sim

env = sim.Environment()
env.run()

Requires Python 3.7 or later; animation features may require additional system libraries depending on your platform.

Verify before relying:

- Whether animation features work out-of-the-box on all platforms or require separate graphics library installation.
- Performance characteristics and scalability limits for large-scale simulations.
- Whether the package is suitable for real-time simulation or primarily for offline modeling.
