It is used in all three notebooks.figures: folder containing the figures used in the article, generated by the notebook3_results_and_analysis.tables: folder containing data tables used as supplementary information for the approach using a lifetime distribution, generated by the notebook3_results_and_analysis.
The repaired high-voltage motor case is based on confidential data. The case is published in Jerome et al. (2023). The notebook 2_hv_motor_database_creation provides information on the ecoinvent datasets used and the functions to generate a simplified database using only data that are available in Jerome et al. (2023). The results and figures obtained in 3_results_and_analysis are therefore not exactly the same as in the article. However, the
