The shared Jupyter notebooks are meant to replicate the results of the paper.

Each notebook has the same simple structure:

• Read simulation results and city specific data -> create a results dataframe called “sim_stats_df”
• (eventually) compute new metrics from the one available in sim_stats_df
• (eventually) configure economic parameters in a provided .json configuration
• Plot results

The folder is structured as follows:

• figg_4a_4b_5a_5b.ipynb
  • In this notebook it is possible to study unsatisfied demand and charging handling time as a function of fleet size and number of charging poles.
• figg_4c_5c.ipynb
  • In this notebook it is possible to study unsatisfied demand and charging handling time as a function of number of charging zones.
• figg_6_7_11_12.ipynb
  • In this notebook it is possible to study unsatisfied demand and profit as a function of lambda in case of under-sized and over-sized charging infrastructure. Cost and revenue parameters are easily modifiable to check alternative scenarios.
• figg_9_10_13_14.ipynb
  • In this notebook it is possible to study unsatisfied demand and profit as a function of fleet size and number of chargers. Cost and revenue parameters are easily modifiable to check alternative scenarios.
• simulation_results: folder containing configurations (.json) and results (.csv, .pickle) of the whole simulation campaign.
• figures: folder containing plots created in the notebook.
• ieee_iscc2020.mplstyle: configuration file for plotting style.
