Modeling of Access Control System using Petri-nets
نویسنده
چکیده
In this paper we purpose a Petri-net-based method for describing the model of an object-oriented design of Access Control System (ACS), by specifying the object interaction scenarios as Petri nets with an Augmented Marked Petri Net (AMPN) structure. After synthesizing these scenarios into an integrated net, we analyze the system based on the special properties of AMPN. For unique representation of events and conditions in an object-oriented ACS, an improved algorithm is applied to the integrated labelled Petri net of ACS to eliminate duplicate condition labels and event labels, with preserving the event firing sequences. Object-based behavioural specifications of ACS are then obtained as projections of the integrated labelled Petri nets onto the objects. For the illustration we present the model of Office access control system in any academic or industry. Keywords—Access control System; Petri net; Augmented marked Petri net Graph; Resources; Siphon.

Modeling of Continuous Systems Using Modified Petri Nets
Due to the changes which may occur in their parameters, systems are usually demonstrated by some subsystems for different conditions. This paper employs Modified Petri Nets (MPN) to model theses subsystems and makes it simple to analyze them. In this method, first, the continuous transfer function is converted to a discrete transfer function and then, by MPN, system is modeled and analyzed. All...
متن کاملUsing Interval Petri Nets and Timed Automata for Diagnosis of Discrete Event Systems (DES)
A discrete event system (DES) is a dynamic system that evolves in accordance with the abrupt occurrence, at possibly unknown irregular intervals, of physical events. Because of the special nature of these systems, different tools are currently used for their analysis, design and modeling. The main focus of this paper is the presentation of a new modeling approach of Discrete Event Systems. The ...

متن کاملHybrid Time Delay Petri Nets as a Mathematical Novel Tool to Model Dynamic System with Current Sample Time
The existing modeling methods using Petri Nets, have been successfully applied to model and analyze dynamic systems. However, these methods are not capable of modeling all dynamic systems such as systems with the current sample time signals, systems including various subsystems and multi-mode systems. This paper proposes Hybrid Time Delay Petri Nets (HTDPN) to solve the problem. In ...
