Presentation / Conference Contribution
Moro, A., Yu, H., & Kelleher, G. (2000). Advanced scheduling methodologies for flexible manufacturing systems using Petri nets and heuristic search. In Proceedings 2000 ICRA. Millennium Conference. IEEE International Conference on Robotics and Automation

The combination of Petri net (PN) and AI to solve flexible manufacturing systems (FMS) scheduling problems has been proven to be a promising approach. However, the NP-hard nature of the problem prevents the PN capability of reasoning about the behavi...
