Clutter is the random yet structured placement of objects in a room. We describe a procedural clutter generator that achieves believable, varied, and controllable object placement using a hierarchical colored Petri net capable of expressing any computable set of object placement constraints.

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.

A parametric Colored Petri net model of the switched Ethernet network with the tree-like topology is developed. The model’s structure is the same for any given network and contains fixed number of nodes. The tree-like topology of a definite network is given as the marking of dedicated places. The model represents a network containing workstations, servers, switches, and provides the evaluation ...

A Colored Petri Net implementation of the mathematical model of a decision making organization that forms the basis of an experiment currently being carried out is presented. The model is used to investigate coordination mechanisms by decoupling the information flow paths and the coordination mechanisms into two interacting layers in which the coordination layer coordinates the behavior of the ...

In this work, Session Initiation Protocol model is established by using Timed Colored Petri Nets (TCPN). SIP (Session Initiation Protocol) is a protocol developed to assist in providing advanced telephony services across the Internet. The Session Initiation Protocol (SIP) has become the quasi-standard for VoiceoverInternet Protocol (VoIP) communications. SIP is based on a client-server infrastr...

Distributed Intelligence Systems (DIS) consist of interconnected intelligent nodes that carry out tasks in coordination. The intelligence in the nodes may be due to humans, to machines, or to a combination of human and machine, such as a human with a workstation. An earlier model of an intelligent node was based on ordinary Petri Nets with switches and led to several approaches for the design o...

Aiming at the difficulty in establishing model to describe vehicle running state, real road test was carried out to capture data which represent the movement of vehicles. Coordinate transformation method and transform relationship among different variable parameters were used to establishing represent model of vehicle movement. By using Petri net which had well layering and time sequence, vehic...

In this paper we apply modeling and simulation as an integrated approach to study the patient admission process in a hospital. The span of the processes is of intra and inter-organizational nature, which allows to see the intricacy of organizational processes on one hand, and the process-centric flow of activities on the other hand. This paper resulted from a student research project, where it ...

In this paper we present a Colored Petri Net (CPN) for a multi-agent application. In particular we modeled the Packet-World. In our research we use the packet-world as a case to study the fundamentals of agents' social behavior. Our approach is to combine experiments with conceptual modeling. We start from a very basic model and then add social skills in a modular way. Integrating new social sk...

In this paper the methodology of firewalled LAN models construction in the form of Colored Petri Net is introduced and model the ACL (Access Control List ) in firewalls as the first form of defense for the simulation and analysis of the model the Design/CPN Tools is used The components of the model are Firewall, Switch, Hub, Server and Workstation.
