line-solver 3.0.2.1

Queueing theory algorithms in Python

LINE Solver for Python

This folder includes the Python version of the LINE solver.

Installation

Requirements: Python 3.10 or later.

Documentation

The Python syntax is nearly identical to the MATLAB one, see for example the scripts in the Python gettingstarted/ folder compared to the ones in the corresponding MATLAB gettingstarted/ folder.

A Python version of the manual is also available.

Example

Solve a simple M/M/1 model with 50% utilization running: python3 mm1.py. You should then get as output the following pandas DataFrame

    Station   JobClass   QLen  Util  RespT  ResidT  Tput
0  mySource     Class1    0.0   0.0    0.0     0.0   0.5
1   myQueue     Class1    1.0   0.5    2.0     2.0   0.5

Alternatively, you can open and run mm1.ipynb in Jupyter.

Getting Started Examples

The examples/gettingstarted/ folder contains tutorial examples demonstrating key LINE features. Notable examples include:
