This is the repository for the FM2024 submission ``Stochastic Games for User Journeys'' by Kobialka, Pferscher, Bergersen, Johsen, and Tapia Tarifa.
.
├── data : Folder for event logs
├── greps : Output folder for the GrepS case study, contains Figures 3, 4 and 5
├── journepy : Journey analysis library with parsing modules
├── mc_outputs : Stores the model checking outputs for reproducability
├── out : General output folder, contains Figures 6 and 7
├── queries : Used model checking queries in PRISM-games format
All experiments were tested with Python 3.10.12. To install all required libraries run
pip install -r requirements.txt
For visualizations are additional libraries used:
- plotly for Sankey diagrams
- pygraphviz for plotting graphs
-
Download data sources into
data
-
Install PRISM-games 3.2.1
-
Update the links in the second cell of
io_alergia_greps.ipynb
andio_alergia_bpic17.ipynb
to your local installs. -
Run both notebooks to reproduce all experiments and plots. Due to memory consumption in BPIC'17 needs the Java maximal memory be increaesd to 8GB with
-javamaxmem 8g
. These cells are currently commented out in the notebook.
We present complementary information omitted in the paper due to the page limit.

The bounded success probability for BPIC'17, BPIC'17-1 is in solid lines and BPIC'17-2 in dashed lines:
