Deadlocks are a rather undesirable situation in a highly automated flexible manufacturing
system. Their occurrences often deteriorate the utilization of resources and may lead to …

Cluster tools are automated robotic manufacturing systems containing multiple computer-
controlled process modules. They have been increasingly used for wafer fabrication. This …

Formal methods for the specification and verification of hardware and software systems are
becoming more and more important as systems increase in size and complexity. The aim of …

A variety of important Petri net-based methods to prevent deadlocks arising in flexible
manufacturing systems (FMS) are to add some control places and related arcs to strict …

The authors study a class of specifications, called generalized mutual exclusion constraints,
for discrete event systems modeled using place/transition nets. These specifications may be …

Deadlock problems in flexible manufacturing systems (FMS) have received more and more
attention in the last two decades. Petri nets are one of the more promising mathematical …

This paper exploits the potential of siphons for the analysis of Petri nets, It generalizes the
well-known Commoner condition and is based on the notion of potential deadlocks which …

Deadlock prevention plays an important role in the modeling and control of flexible
manufacturing systems (FMS). This paper presents a novel and computationally efficient …

As more and more producers move to use flexible and agile manufacturing as a way to keep
them with a competitive edge, the investigations on deadlock resolution in automated …

Petri nets are widely used in modeling, analysis, and control of discrete event systems
arising from manufacturing, transportation, computer and communication networks, and web …
