Petri Net Induced Heuristic Search for Resource Constrained Scheduling
The article presents a new approach to the Resource-Constrained Project Scheduling Problem (RCPSP) using a Timed Transition Petri Net. The authors demonstrate that their heuristic search method outperforms traditional Mixed-Integer Linear Programming baselines in both success rate and solve time. This research was accepted at the International Symposium on Combinatorial Search in 2026.
- ▪The study formulates RCPSP as optimal search over the reachability graph of a Timed Transition Petri Net.
- ▪The proposed method uses A* guided by a heuristic that combines Critical Path and resource-based lower bounds.
- ▪Experiments show that the approach outperforms strong exact MIP baselines in success rate and solve time.
