Presented herein is a methodology for quantitatively analyzing the complex signaling network by resorting to colored Petri nets (CPN). The mathematical as well as Petri net models for two basic reaction types were established, followed by the extension to a large signal transduction system stimulated by epidermal growth factor (EGF) in an application study. The CPN models based on the Petri net...

Petri Nets (P-nets) are widely used in many fields. Because of their simple working, many formal analysis and synthesis methods are applicable to them, and furthermore P-net-based software tools can be implemented with relative ease. However, P-nets are inconvenient to use in very large and complex applications. Colored Petri Nets (CP-nets) provide much more convenience and compactness than P-n...

We propose rewriting logic as a unifying framework for a wide range of Petri nets models. We treat in detail place/transition nets and important extensions of the basic model by individual tokens, test arcs, and time. Based on the idea that “Petri nets are monoids” suggested by Meseguer and Montanari we define a rewriting semantics that maps place/transition nets into rewriting logic specificat...

In this paper we use colored Petri nets (CPNs) and the supporting CPN Tools for the modeling and performance analysis of grid architectures. The notation of Petri nets is a well known graphical formalism, able to model concurrency and different types of communication. CPNs extend Petri nets with timing, hierarchy, data, and programming language constructs, which makes them suitable for the mode...

    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...

Reuse has long been recognized as a key technology that can bring about signi cant productivity gains in software development. Code-level reuse is wellunderstood and frequently practiced. However, reuse in software requirements, another phase where much bene t can be expected, remains inadequately addressed. Hierarchical Colored Petri Net (HCPN) formalism has been successfully used on several l...

We present a new class of Petri Nets, called Extended Simple Colored Petri Nets (ESCP-nets), which are essentially Simple Colored Petri Nets (SCP-nets) with three added features: first, there is a built-in type of real numbers; second, tokens can be forced to wait in places; third, an interface specifies how the Net can be externally supervised. Even if these added features also add complexity,...

Abstract: Aero-engines maintenance procedure can be treated as a typical discrete event dynamic system. A theory that synthesized timed colored Petri net is proposed. The theory adopts a bottom-up approach by merging all sub modules, and each one characterizes the critical resource contention among processes. Nevertheless Petri net seems inapplicable to dynamic scheduling modelling because of i...

In this paper, we develop a syntactical version of elaborated reductions for high-level Petri nets. These reductions simplify the model by merging some sequential transitions into an atomic one. Their conditions combine local structural ones (e.g. related to the actions of a thread) and global algebraic ones (e.g. related to the threads synchronization). We show that these conditions are perfor...

Improve the quality of web service composition using the petri nets and ontology. Previously web services are design independently. These kinds of services are not compatible. We observe the different security issues. Now in this paper we design new semantic web networks using petri nets and ontology. Start the interaction process levels display the decisions using colored petri nets environmen...
