The production scheduling problem allocates limited resources to tasks over time and
determines the sequence of operations so that the constraints of the system are met and the …

In this survey we review the current complexity status of basic cyclic scheduling models. We
start with the formulations of three fundamental cyclic scheduling problems, namely the …

In this paper, we consider a cyclic job shop problem, consisting of production of a certain set
of elements at fixed intervals. Optimization of the process is reduced to a minimization of a …

This paper presents the design and the implementation of a Petri net (PN) model for the
control of a flexible manufacturing system (FMS). A flexible automotive manufacturing …

This paper proposes to use a Petri net framework together with simulation technology to
model and analyse distributed manufacturing networks. With the distinct modelling features …

This paper proposes a new Petri net class, namely, Ratio-enforced weighted Augmented
Marked Graphs (RAMGs), and solves ratio control and liveness-enforcing supervision …

In the context of automated manufacturing, this work proposes a new special class of timed
Petri nets, namely, Timed ratio-enforced Augmented Marked Graph (TAMG) and its low-cost …

In automated manufacturing systems (AMSs), Petri nets are widely adopted to solve
supervisory control problems. Among them, how to enforce liveness and fairness for AMS …

Scheduling problems have been approached several times by Petri nets. Indeed, the usage
of a Petri net model guarantees the feasibility of the candidate solutions, but it does not …

Owing to intense global competition, one of the main concerns of the production-scheduling
literature is the modelling and the optimisation of the robotic cells. In this type of cell, as in a …
