Today there are many techniques for web service compositions. Evaluation of quality parameters has great impact on evaluation of final product. BPEL is one of those techniques that several researches have been done on its evaluation. However, there are few researches on evaluation of QoS in eflow. This research tries to evaluate performance and reliability of eflow and BPEL through mapping them...

A new approach to model multi-agent systems with hierarchical colored Petri nets is introduced. Every agent has its colored Petri net system, when agents are composed into a MAS, we get hierarchical colored Petri net system of the multi-agent system, properties of the hierarchical colored Petri net system, such as reachability, deadlock detection and avoidance, fairness can be used to analyze d...

Based on the Petri net definitions and theorems already formalized in the Mizar article [13], in this article we were able to formalize the definition of cell Petri nets. It is based on [12]. Colored Petri net has already been defined in [11]. In addition, the conditions of the firing rule and the colored set to this definition, that defines the cell Petri nets are further extended to CPNT.i fu...

Biometric Identification Protocol with Random Parameter is modelled in the current paper by using Petri Nets, namely with the modern extension of Petri Nets-Colored Petri Nets. The purpose of modelling Biometric Identification Protocol with Random Parameter by the use of Petri Nets is to reveal the following aspects of the functioning model: The efficiency of the model; Behaviour; The existence...

In this paper we propose a method for implementing a full structural model refinement of a (biological) model represented as a (colored) Petri net. We build on the full structural data refinement definition of C. Gratie and Petre, and the type refinement of colored Petri nets introduced by Charles Lakos. Given a (biological) reaction-based model and a desired full structural refinement of it, w...

In Agent Based Scheduling and Planning Systems, autonomous agents are used to represent enterprises and operating scheduling/planning tasks. As application domains become more and more complex, agents are required to handle a number of changing and uncertain factors. This requirement makes it necessary to embed state prediction mechanisms in Agent Based Scheduling and Planning Systems. In this ...

The article studies the interrelation of Languages of Colored Petri Nets and Traditional formal languages. The author constructed the graph of Colored Petri Net, which generates L Context-free language. This language may not be modeled using standard Petri Nets [1]. The Venn graph and diagram that the author modified [1], show the interrelation between languages of Colored Petri Nets and some T...

Petri nets have become an effective formalism to model biological systems. However, attempts to simulate biological systems by low-level Petri nets are restricted to relatively small models, and they tend to grow quickly for modeling complex systems, which makes it more difficult to manage and understand the nets. Motivated by this, we propose a colored Petri net-based framework for modeling, s...
