The ability to deploy wireless patient monitors using industry-standard IEEE 802.x technologies allows patient mobility and clinical flexibly. However, interconnecting multiple life-critical medical devices from multiple vendors can introduce unintended life-threatening risks unless delivery of critical patient alarms to central monitoring systems and/or clinical personnel is assured. Petri net...

The goal of the Resource Reservation Protocol (RSVP) is to support the provision of the Quality of Service required for emerging Internet applications (such as video conferencing) that require a level of performance not guaranteed by the Internet. RSVP attempts to provide performance guarantees by establishing resource reservations (such as the number of buffers and bandwidth allocation) within...

The development of Coloured Petri Nets (CP-nets or CPN) has been driven by the desire to develop a modelling language – at the same time theoretically well-founded and versatile enough to be used in practice for systems of the size and complexity found in typical industrial projects. To achieve this, we have combined the strength of Petri nets with the strength of programming languages. Petri n...

This paper introduces Access/CPN 2.0, which extends Access/CPN with high-level primitives for interacting with coloured Petri net (CPN) models in Java programs. The primitives allow Java programs to monitor and interact with places and transitions during execution, and embed entire programs as subpages of CPN models or embed CPN models as parts of programs. This facilitates building environment...

This article presents several diierent kinds of Petri nets, together with computer tools based on them, and compares possibilities of their application in the area of simulation and modelling. Place/transition Petri nets, stochastic Petri nets, hierarchical coloured Petri nets and nally object oriented Petri nets are mentioned here. As for the tools, Design/CPN, TimeNET, LOOPN++ and PNtalk are ...

ETCS Level 2 (European Train Control System Level 2, ETCS-2) has drawn particularly attention from researchers and industries. A new CPN model-based formal approach for test cases and sequences generation is proposed in this paper to increase the test automation degree of the ETCS-2 system and subsystems. In this paper, a set of modelling rules is presented firstly to make the Coloured Petri Ne...

Bang & Olufsen A/S (B&O) is a renowned manufacturer of audio and video products. Their BeoLink® (BeoLink) system distributes sound and vision throughout a home via a network. In this way, e.g., while doing the cooking in the kitchen, a person can remotely select and listen to a track from a CD loaded in the CD player situated in the living room. To resolve connicts, synchronisation between vari...

Many models in Systems Biology are described as a system of Ordinary Differential Equations, which allows for transient, steady-state or bifurcation analysis when kinetic information is available. Complementary structure-related qualitative analysis techniques have become increasingly popular in recent years, like qualitative model checking or pathway analysis (elementary modes, invariants, flu...

Cutaneous symptoms are observed in 25%-60% of polyarteritis nodosa (PN) patients. On the other hand, cutaneous polyarteritis nodosa (CPN) is designated for the cutaneous limited form of PN and demonstrates benign prognosis. However, there has been much debate on whether or not CPN can progress to PN. Although CPN lesions are fundamentally limited to skin, some CPN cases show extracutaneous symp...

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...
