SFILES 2.0

This repository is published together with the paper: SFILES 2.0: An extended text-based flowsheet representation
The repository contains functionality for the conversion between PFD-graphs/P&ID-graphs and SFILES 2.0 strings. In the paper, we describe the structure of the graphs, notation rules of the SFILES 2.0, and the conversion algorithm.

How to use this repository?

To use the SFILES 2.0 code, first clone the repository:

git clone https://github.com/process-intelligence-research/SFILES2.git

After creating and activating a new virtual environment (python 3.9), you can use the requirements.txt file to install all required packages:

pip install -r requirements.txt

The repository contains a notebook for demonstration. To use this notebook, you need to install the ipykernel:

source activate envname # activate environment
python -m ipykernel install --user --name envname --display-name "Python (envname)"

Demonstration of functionality

You can either have a look at the demonstration.ipynb which demonstrates SFILES 2.0 strings for a variety of PFDs and P&IDs or run the python file run_demonstration.py.
