The use of the UML specification language for modelling dynamic behaviors of systems is very widespread. UML Statecharts and Collaboration diagrams are widely used to model dynamic behaviors of systems. However, the lack of firm semantics for the UML modeling notations makes the detection of behavioral inconsistencies difficult in the initial phases of development. The use of formal methods mak...

This paper deals with the modelling of batch systems by means of high-level Petri nets. Batch systems are systems that transform a continuous raw material through continuous equipment (as heat exchanger for example) and batch equipment (for instance, batch reactor). These systems are frequently used by chemical of food industry. Batch systems deal with concurrent activities and resource allocat...

We apply three different modeling frameworks — timed automata (Uppaal), colored Petri nets and synchronous data flow — to model a challenging industrial case study that involves an existing stateof-the-art image processing pipeline. Each of the resulting models is used to derive schedules for multiple concurrent jobs in the presence of limited resources (processing units, memory, USB bandwidth,...

Algebraic Petri nets is a well suited formalism to represent the behavior of concurrent and distributed systems by handling complex data. For the analysis of systems modelled in Algebraic Petri nets, model checking and testing are used commonly. Petri nets slicing is getting an attention recently to improve the analysis of systems modelled in Petri nets or Algebraic Petri nets. This work is ori...

The methodology of switched LAN models construction in the form of colored Petri net is introduced. For the simulation and analysis of the model the Design/CPN tool is used. The tasks of estimation of LAN switch’s buffer size and network response time were solved. The components of the model are switches, servers, and workstations. © 2004 IMACS.

Petri nets structural techniques may be used not only to study interesting system properties, but also to manage state space explosion and discrete-event simulation complexity. In order to avoid net unfolding, a symbolic calculus for high level PN structural analysis is needed, directly working on net annotations. Colored Petri Nets structural analysis relies upon a common subset of functional ...

Case handling is a new paradigm for supporting flexible and knowledge intensive business processes. It is strongly based on data as the typical product of these processes. Unlike workflow management, which uses predefined process control structures to determine what should be done during a workflow process, case handling focuses on what can be done to achieve a business goal. While classical Pe...

Protos is a popular tool for business process modelling used in more than 1500 organizations. It has a built-in Petri-net-based simulation engine which shows key performance indicators for the modelled processes. Reference process models offered for Protos reduce modelling efforts by providing generic solutions which only need to be adapted to individual requirements. However, the user can neit...

Petri nets have been widely used to model dynamic systems, namely manufacturing systems. In this paper we introduce the use of Petri nets to model robotic tasks. Diierent views of the robotic task model can be modeled by distinct Petri net types: interpreted Petri nets for task design and execution, generalized stochastic Petri nets for task quantitative performance evaluation and ordinary Petr...
