A free and open implementation of the Treatment Centre Model from Nelson (2013)
Project description
Towards Sharing Tools, and Artifacts, for Reusable Simulation: a minimal model example
Overview
The materials and methods in this repository support work towards developing the S.T.A.R.S healthcare framework (Sharing Tools and Artifacts for Reuable Simulations in healthcare). The code and written materials here demonstrate the application of S.T.A.R.S' version 1 to sharing a simpy
discrete-event simuilation model and associated research artifacts.
- All artifacts in this repository are linked to study researchers via ORCIDs;
- Model code is made available under an MIT license;
- Python dependencies are managed through
conda
;` - Documentation of the model is enhanced using a Jupyter notebook.
- The python code itself can be viewed and executed in Jupyter notebooks via Binder;
- The materials are deposited and made citatable using Zenodo;
- The model is sharable with other researchers and the NHS without the need to install software.

This code is part of independent research supported by the National Institute for Health Research Applied Research Collaboration South West Peninsula.

Instructions to run the model
Online Notebooks via Binder
The python code for the model has been setup to run online in Jupyter notebooks via binder
mybinder.org is a free tier service. If it has not been used in a while Binder will need to re-containerise the code repository, and push to binderhub. This will take several minutes. After that the online environment will be quick to load.
To download code and run locally
Downloading the code
Either clone the repository using git or click on the green "code" button and select "Download Zip".
git clone https://github.com/pythonhealthdatascience/stars-treat-sim
Installing dependencies
All dependencies can be found in binder/environment.yml
and are pulled from conda-forge. To run the code locally, we recommend install mini-conda; navigating your terminal (or cmd prompt) to the directory containing the repo and issuing the following command:
conda env create -f binder/environment.yml
Activate the conda environment using the following command
conda activate stars_treat_sim
Running the model
To run 50 multiple replications of across a number of example experiments use the following code
from treat_sim.model import (get_scenarios, run_scenario_analysis,
scenario_summary_frame,
DEFAULT_RESULTS_COLLECTION_PERIOD)
if __name__ == '__main__':
results = run_scenario_analysis(get_scenarios(),
DEFAULT_RESULTS_COLLECTION_PERIOD,
n_reps=50)
results_summary = scenario_summary_frame(results)
print(results_summary)
Alternative you can design and execute individual experiments by creating a Scenario
object
from treat_sim.model import Scenario, multiple_replications
if __name__ == '__main__':
# use all default parameter values
base_case = Scenario()
results = multiple_replications(base_case).describe().round(2).T
print(results)
