Object Petri Nets: Definitions, Properties, and Related Models
نویسنده
چکیده
In this presentation the decidability issues of formalisms that allow Petri nets as tokens are studied. Especially for “elementary object-net systems” defined by Valk the decidability of the reachability and the boundedness problem is considered. It is shown that reachability becomes undecidable while boundedness remains decidable for elementary object-net systems. Furthermore it is shown that even for minimal extensions the formalism obtains the power of Turing machines.

Soccer 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 کاملAvailability evaluation of Software architecture of object oriented Style using coloured Petri nets
Software architecture is one of the most fundamental products in the process of software development in the areas of behavioral or non- behavioral features like availability or transformability change. There are different ways to evaluate software architecture one of which is the creation of application model. An executable model of software architecture is an official description of architectu...
متن کاملModeling 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 کاملPetri Nets for Object-Oriented Modeling
Ensuring the correctness of concurrent programs is difficult, since common approaches for program design do not provide appropriate methods. This paper gives a brief introduction to Object Colored Petri Nets, which can be used for modeling the control flow of concurrent programs, for their simulation, and for deriving and proving specific properties. Emphasis will not rely upon the precise form...
متن کاملMapping CRC Card into Stochastic Petri Net for Analyzing and Evaluating Quality Parameter of Security (TECHNICAL NOTE)
CRC cards are unconventional method for identifying and describing classes, behavior and its responsibilities and collaborators of class. Representation of three categories of class, responsibilities and collaborators can give proper image of scenario. These cards are effective method for analyzing scenarios. With all positive features of CRC cards, of weaknesses of these cards are failure to s...
