Implementation of the State-Task-Network (STN) [Kondili et al. 1993] with degradation of equipment. This code can be used to replicate the results in [Wiebe et al. 2018] available at arXiv:1810.09289.
This implementation is based on the STN-Scheduler by Jeffrey Kantor (c) 2017.
Generate data for logistic regression by solving short-term scheduling model repeatedly for different demands:
python lhs.py runs/test_lhs.yaml
where runs/test_lhs.yaml is a config file.
Train logistic regression for Markov-chain or frequency approach.
Solve model using rolling horizon:
python rolling runs/test_det.yaml
Solve model using Markov-chain or frequency approach:
python mc.py runs/test_mc.yaml
Optimize uncertainty set size using Bayesian Optimization:
python bo.py runs/test_bo.yaml prefix_for_file_names
