Ontological approach to modelling of discrete event dynamic system

Application of Discrete Event System to Insect Population Dynamic

This work describes an application of queueing network to model the insect population. The interarrival time and service time are both exponentially distributed. Preliminary results have been obtained to show the development of the insect population. Future work for the model’s potential development and uses are also discussed.

A Hybrid Discrete Event Dynamic Systems Approach to Robot Control

System Model Symbolic Events Control Activation Continuous Control Modules / Event Generators Physical Sensors Physical Actuators G G G G G Figure 15: Supervision of a Hybrid DEDS Here the continuous control part acts as an interface between the symbolic DEDS model and the the continuous system and environment. Depending on the characteristics of these controllers, the resulting system model an...

Time Management Approach on a Discrete Event Manufacturing System Modeled by Petri Net

    Discrete event system,   Supervisory control,   Petri Net, Constraint   This paper presents a method to manage the time in a manufacturing system for obtaining an optimized model. The system in this paper is modeled by the timed Petri net and the optimization is performed based on the structural properties of Petri nets. In a system there are some states which are called forbidden states an...

ABCmod: a conceptual modelling framework for discrete event dynamic systems

Hybrid Modelling in Discrete-Event Control System Design

Simulation-based testing of discrete-event control systems can be advantageous. There is, however, a considerable difference between languages for real-time control and simulation languages. The χ language, presented in this paper, is suited to specification and simulation of realtime control systems. The hybrid nature of the language makes it also suited to modelling of controlled machines. By...
