In this paper, we extend the supervisory control theory and a supervisor synthesis problem to a class of colored Petri nets. More speciically, we investigate the forbidden state control problem with full observation in which the discrete-event system is modeled as a colored Petri net with a symmetry speciication. This problem is decidable if the colored Petri net has nite color sets and bounded...

Testing requirements in the earlier stages of system design is a necessary step in system development. Mobile TV system has been in the spotlight due to widespread use of smart devices. Nowadays, most people in public transportation watch TV programs on their smartphones. However, this activity consumes a lot of smartphone battery power. The solution to this problem can be a cloud-based mobile ...

The paper presents the current status of the software tool TimeNET. It supports modeling and performance evaluation of stochastic models, including extended deterministic and stochastic Petri nets, colored stochastic Petri nets, and Markov chains as well as UML extensions. Among its main characteristics are simulation and analysis modules for stationary and transient evaluation of Petri nets in...

In this paper, we propose a modeling tool named QCPN (Queueing Colored Petri Net). The main idea of this tool is to combine the original CTPN (Colored Timed Petri Net) with the queueing systems. With QCPN model, we can predict the delivery date of any specific product under some scheduling policies eflcientfy and rather precisely. In the scheduling phase. we use the GA based approach to search,...

We describe a case study of the design and verification of a parallel image processing unit based on an extended Petri net, which is called a Logical Colored Petri net (LCPN). This is suitable for Flexible-Manufacturing System (FMS) modeling and discussion of structural properties. LCPN is another family of colored p/t-net (CPN) with the addition of the following features: integer value assignm...

A single wafer processing IC fabrication with flexible and distributed configuration is getting more important. The cluster tool is such an IC fabrication equipment. It consists of the cassette module, transport module, and process module. In this paper, the model of a cluster tool is constructed using distributed colored timed Petri net (DCTPN). The emulator and controller of the cluster tool ...

State space explosion is one of the biggest problem in model checking. Predicate abstraction technique is used to reduce the size of state space of colored Petri net models, and an algorithm was proposed to obtain the abstracted state space of a colored Petri net model without its original state space generated. A method to verify safety properties of Web service composition by abstracted state...
