sim-tools 1.3.0

Simulation Tools for Education and Practice

Tools to support Discrete-Event Simulation (DES) and Monte-Carlo Simulation education and practice

sim-tools is being developed to support Discrete-Event Simulation (DES) and Monte-Carlo Simulation education and applied simulation research. It is MIT licensed and freely available to practitioners, students and researchers via PyPi and conda-forge

Vision for sim-tools

1. Deliver high quality reliable code for DES and Monte-Carlo Simulation education and practice with full documentation.
2. Provide a simple to use pythonic interface.
3. To improve the quality of simulation education using FOSS tools and encourage the use of best practice.

👥 Authors

• Thomas Monks   

• Amy Heather   

• Alison Harper   

Features:

1. Implementation of classic Optimisation via Simulation procedures such as KN, KN++, OBCA and OBCA-m
2. Theoretical and empirical distributions module that includes classes that encapsulate a random number stream, seed, and distribution parameters.
3. An extendable Distribution registry that provides a quick reproduible way to parameterise simulation models.
4. Implementation of Thinning to sample from Non-stationary Poisson Processes (time-dependent) in a DES.
5. Automatic selection of the number of replications to run via the Replications Algorithm.
6. EXPERIMENTAL: model trace functionality to support debugging of simulation models.

Installation

Pip and PyPi

pip install sim-tools

Conda-forge

conda install -c conda-forge sim-tools

Mamba

mamba is a FOSS alternative to conda that is also quicker at resolving and installing environments.

mamba install sim-tools
