Formalisms for modelling the discrete manufacturing systems
2009 IEEE International Conference on Mechatronics, 2009Considering that in a discrete manufacturing system the production rates of machines are stochastic and not equal, we focus on transient analysis of Markov models. The system is decomposed resulting in reduced computation burden into several base-elements, which determine the event occurrence such as: a machine fails, a machine is repaired, a buffer ...

Applications of discrete-event state equations to manufacturing systems
1999 7th IEEE International Conference on Emerging Technologies and Factory Automation. Proceedings ETFA '99 (Cat. No.99TH8467), 2003The paper addresses the problem of modelling and controlling manufacturing systems within the framework offered by the Manufacturing Algebra (MA). The method is outlined through a case study, including production micro- and macro-irregularities. The design of a hierarchical real time controller capable of satisfying the demand of finished products ...

A Taxonomy of Discrete Manufacturing Systems
Operations Research, 1991This paper proposes a classification scheme for discrete manufacturing systems. It also includes a brief discussion of modeling, analysis, and optimization techniques that have been applied to manufacturing. This taxonomy is intended to be a first step in fitting existing environments to models.

Montoring Manufacturing System Behavior by Continuous Discrete-Event Simulation
Proceedings of 1993 Winter Simulation Conference - (WSC '93), 1993A simulation environment (COGNOSCO) designed to monitor the evolution of manufacturing systems is presented. Assuming that today manufacturing simulation is dedicated to (long term) system design or to (short term) scheduling, this environment is an attempt to address the continuum of decisions that lie between these two, extremes.

Observers for discrete-event manufacturing systems
Proceedings IECON '91: 1991 International Conference on Industrial Electronics, Control and Instrumentation, 2002The author describes the design of observers for a class of discrete-event dynamic systems where events can become unobservable in real time. He defines a novel temporal model that augments a finite state machine to describe both the temporal and behavioral attributes of the system.

Discrete-event modeling and control of manufacturing systems
Proceedings of the 1998 IEEE International Conference on Control Applications (Cat. No.98CH36104), 2002In this article discrete-event state equations are applied to model and control manufacturing systems. Their input and output variables and the state itself are formulated in a suitable space of event sequences. Events are defined as pairs (fact, time), the fact being an element of the quantity space of the manufacturing objects produced, consumed and ...

Energy Consumption Model of the Discrete Manufacturing System
2020For the discrete manufacturing system, its energy consumption and its facility condition have closely connections with its other factors, such as motion properties, technical parameters, a ranking of technical features, product structure, production scheduling and commitment control.

Digital Control of Discrete Event Manufacturing Systems 1
IFAC Proceedings Volumes, 1994Abstract A matrix framework is developed for modelling the workcell dynamics and designing digital controllers. The workcell functions are seperated from the controller, in the contrast to the Petri-net model where the workcell and the controller functions are undifferentiated This framework unites the industrial engineering approaches with the petri-

PETRI NET MODEL RECONFIGURATION OF DISCRETE MANUFACTURING SYSTEMS
IFAC Proceedings Volumes, 2006Abstract The fault recovery problem of discrete manufacturing systems is addressed through reconfiguration of Petri net models. The notion of reconfigurability is introduced and characterised; then a polynomial procedure for determining this property is proposed. Finally, a graph rewriting based procedure for reconfiguration is presented.

Discrete-event modeling of heterarchical manufacturing control systems
2004 IEEE International Conference on Systems, Man and Cybernetics (IEEE Cat. No.04CH37583), 2005This paper is concerned with a systematic modeling and design methodology for multi-agent control systems in manufacturing environments. The basic idea of the proposed approach is to develop discrete-event dynamical models of the single atomic decision entities (agents), and then to derive a model of the whole control network by specifying the ...
