uml is known as one of the most common methods in software engineering.since this language is semi-formal, many researches and efforts have beenperformed to transform this language into formal methods including petri nets.thus, the operation of verification and validation of the qualitative and nonfunctionalparameters could be achieved with more ability. since the majority of thereal world info...

This paper gives the Petri net ontology as the most important element in providing Petri net support for the Semantic Web. Available Petri net formal descriptions are: metamodels, UML profiles, ontologies and syntax. Metamodels are useful, but their main purpose is for Petri net tools. Although the current Petri-net community effort Petri Net Markup Language (PNML) is XMLbased, it lacks a preci...

This paper introduces a new direction in formalizing sociological models. Sociological theories are a field of application for computer science, hence sociologists describe a theory in informal ways. These theories are transformed into computational models which can be studied and investigated with formal methods. We have chosen to formalize a common model of sociological theory, the Garbage Ca...

To evaluate and predict component-based software security, a two-dimensional model of software security is proposed by Stochastic Petri Net in this paper. In this approach, the software security is modeled by graphical presentation ability of Petri nets, and the quantitative prediction is provided by the evaluation capability of Stochastic Petri Net and the computing power of Markov chain. Each...

To achieve high performance in agent-based cooperative design, the effective allocation of design agents to distributed and cooperative design tasks becomes a crucial issue. This research extends the well-known contract net protocol for decentralized task allocation in cooperative engineering design. Since the contract net protocol only provides a generic framework for agents to exchange and ev...

Petri net is used widely to analyze and model various systems formally. Recently, Many Petri nets mania devote their efforts to enhancing and extending the expressive Power of Petri nets. One such effort is to extend Petri nets with object-oriented concepts. An object-oriented paradigm provides excellent concepts to model real-world problems. Object-oriented concepts allow us to build software ...
