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...

Electronic commerce protocols are the basis of security in electronic commerce. Therefore, it is essential to ensure these protocols correctly. With the ideas of ZQ logic and the security protocols analysis method using Colored Petri Nets, a new method synthesizing ZQ logic and Colored Petri Nets is presented to analyze electronic commerce protocols. The new method is suitable for analyzing bot...

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 ...

Colored Petri Nets (CP-nets or CPNs) are powerful modeling language for concurrent systems. As CPNs' model checking, the mainstream method is unfolding that transforms a CPN into an equivalent P/T net. However net tends to be too enormous handled. checking models without unfolding, we present three practical on-the-fly verification methods which all focused on how make state space generation mo...

Modeling and performance evaluation play a major role for the design of today’s manufacturing systems. This paper adresses the modeling of manufacturing systems with Petri nets. A new method is proposed, facilitating the independent modeling of the manufacturing system’s structure and the production routes of the parts being processed. Both models use the same specialized type of Colored Petri ...

One major difficulty that faces developers of concurrent and distributed software is analysis for concurrency based faults like deadlocks. Petri nets are used extensively in the verification of correctness of concurrent programs. ECATNets are a category of algebraic Petri nets based on a sound combination of algebraic abstract types and high-level Petri nets. ECATNets have 'sound' and 'complete...
