Scripts

Python scripts in the folder and the ilp_petri_net_repair provide auxiliary functionalities to handle PNML and XES data (e.g., mapping them to ASP facts and ILASP examples). Refer to their usage into the *.sh script or in the command line args description.

Requirements

• Install ILASP v4.4.0: https://github.com/ilaspltd/ILASP-releases/releases
• Python lib in requirements.txt

Repair Petri net with ILASP

Given a directory $DIR with a PNML file (Petri net) and a XES (log), and the file defining the considered edits pi_H.lp, to create the ASP model pi_M.lp and the examples from the log, run:

./create_ASP_model_and_examples.sh 

To solve the LAS task (considering also the structural requirements in struct_examples.las) run:

./create_H_and_solve.sh

Experiments

Experiment 1

The following script finds the edits for the models identified with Alpha Miner (Sect 4.1)

./exp_1.sh 

The results can be found in the directory ./experiments_1/

Experiment 2

The following script runs the ILASP for each damaged model in /experiments_2/ (Sect 4.2)

./exp_2.sh

The results can be found in the file ./experiments_2/results.txt To create a new random set of damaged models, run

./exp_2_create_damaged_model.sh
