Abstract:

Absence of deadlocks is critical in systems which are required to operate in a continuous way, such as life-support systems, supervisory control systems (e.g., in a nuclear plant), transportation control systems, and so on. Efficient methods of deadlock detection are of primary importance for such systems. A structural approach to deadlock detection in Petri nets, based on a reduced number of minimal and basis siphons, is proposed in this paper.

Keywords:

Petri nets, deadlock detection, structural methods, minimal siphons, basis siphons, linear programming.
