Grading dozens of Petri net models manually is a tedious and error-prone task. In this paper, we present Grade/CPN, a tool supporting the grading of Colored Petri nets modeled in CPN Tools. The tool is extensible, configurable, and can check static and dynamic properties. It automatically handles tedious tasks like checking that good modeling practise is adhered to, and supports tasks that are ...

Petri nets are graphical and mathematical tools for studying discrete event systems. Petri nets have been under extensive development since Petri defined the language in 1962. Various extensions of Petri nets have been developed to study concurrent, asynchronous, distributed, parallel, deterministic, and stochastic system behavior. This paper provides a quick tutorial to learn the basic termino...

One of the challenging problems for software developers is guaranteeing that a system as built is consistent with its architectural design. In this paper we describe a technique that uses run time observations about an executing system to construct an architectural view of the system. In this technique we develop mappings that exploit regularities in system implementation and architectural styl...

CPN Tools is a tool for modeling, simulating, and analyzing colored Petri nets. The latest iteration of the tool, CPN Tools 4, extends this with constraints known from declarative languages such as Declare and DCR Graphs. Furthermore, this version introduces an explicit process perspective, powerful extensibility allowing third parties to extend the tools capabilities, and a visualization persp...

Thanks to its graphical notation and simplicity, Unified Modeling Language (UML) is a de facto standard and a widespread language used in both industry and academia, despite the fact that its semantics is still informal. The Interaction Overview Diagram (IOD) is introduced in UML2; it allows the specification of the behavior in the hierarchical way. In this paper, we make a contribution towards...

For the analysis of large systems modeled with stochastic Petri nets state explosion is a well known problem Many real life systems are thus impossible to analyze Several research activities try to overcome this limitation Diverse approaches can be found in the literature e g This paper presents an iterative approximation technique for the steady state throughput computa tion of complex concurr...

Cross-organizational business processes are gaining increased attention these days, especially with the service oriented architecture (SOA) as a realization for business process management (BPM). In SOA, interaction agreements between business partners are defined as choreographies containing common interaction patterns. However, complex interactions are difficult to specify, basically because ...

In many research projects on modeling and analyzing biological pathways, the Petri net has been recognized as a promising method for representing biological pathways. From the pioneering works by Reddy et al., 1993, and Hofestädt, 1994, that model metabolic pathways by traditional Petri net, several enhanced Petri nets such as colored Petri net, stochastic Petri net, and hybrid Petri net have b...
