Abstract Fuzzy Petri nets (FPNs) are a potential modeling technique for knowledge
representation and reasoning of rule-based expert systems. To date, many studies have …

Nowadays, manufacturing firms are dealing with the unpredictability of market requirements
and the frequent changes induced by technological innovation. For this reason, firms are …

Resource failures may happen in automated manufacturing systems (AMSs) because of
different reasons in the real world, making most existing deadlock control policies …

This work proposes a novel structure in Petri nets, namely data inhibitor arcs, and their
application to the optimal supervisory control of Petri nets. A data inhibitor arc is an arc from …

This work studies the scheduling problem of a single-arm multicluster tool with a linear
topology and process-bound bottleneck individual tool. The objective is to find a one-wafer …

This paper deals with deadlock problems in Petri nets by adding a set of recovery
transitions. Different from traditional deadlock control methods by deploying control places …

This paper deals with the enforcement of nonlinear constraints on Petri nets. A supervisory
structure is proposed for a class of nonlinear constraints. In order to enforce a nonlinear …

A traditional power transmission system (TPTS) is composed of many electrical substations
(ESs) and transmission lines. When the latter meet faults, the output of the ESs may be …

A robotic cluster tool involves many activities whose time is subject to some disturbance,
thus leading to the activity time variation. It results in wafer sojourn time fluctuation in a …

This paper develops a decentralized supervision policy for a Petri net through collaboration
between a coordinator and subnet controllers. The coordinator is chosen from the subnet …
