A Temporal Logic for Events and States in Petri Nets
نویسندگان
چکیده
In some phases of system development state-based methods are adequate; in others event-based methods are adequate. Petri nets provide a system model which supports both methods and thus allow a smooth transition between the diierent phases of system development. Most temporal logics for Petri nets, however, do not support both methods. In this paper we introduce a temporal logic for Petri nets which allows to argue on states as well as on events. This way, speciications in the early phases can be event based and veriication in later phases can be state-based within a single formalism.

A rule-based evaluation of ladder logic diagram and timed petri nets for programmable logic controllers
This paper describes an evaluation through a case study by measuring a rule-based approach, which proposed for ladder logic diagrams and Petri nets. In the beginning, programmable logic controllers were widely designed by ladder logic diagrams. When complexity and functionality of manufacturing systems increases, developing their software is becoming more difficult. Thus, Petri nets as a high l...

متن کاملSoccer Goalkeeper Task Modeling and Analysis by Petri Nets
In a robotic soccer team, goalkeeper is an important challenging role, which has different characteristics from the other teammates. This paper proposes a new learning-based behavior model for a soccer goalkeeper robot by using Petri nets. The model focuses on modeling and analyzing, both qualitatively and quantitatively, for the goalkeeper role so that we have a model-based knowledge of the ta...
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 ...

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...
