This paper presents a Petri net-based hierarchical architecture for multiple Unmanned Aerial Vehicle (UAV) simulations in order to facilitate rapid prototyping via visual modeling and analysis. Using high-level Colored Petri nets, we specify UAV control structure by a hierarchy of mission control net and task nets: the mission control net, built upon task nets, models the decision making proces...

Petri Nets (P-nets) are widely used in many fields. Because of their simple working, many formal analysis and synthesis methods are applicable to them, and furthermore P-net-based software tools can be implemented with relative ease. However, P-nets are inconvenient to use in very large and complex applications. Colored Petri Nets (CP-nets) provide much more convenience and compactness than P-n...

Reuse has long been recognized as a key technology that can bring about signi cant productivity gains in software development. Code-level reuse is wellunderstood and frequently practiced. However, reuse in software requirements, another phase where much bene t can be expected, remains inadequately addressed. Hierarchical Colored Petri Net (HCPN) formalism has been successfully used on several l...

We present a new class of Petri Nets, called Extended Simple Colored Petri Nets (ESCP-nets), which are essentially Simple Colored Petri Nets (SCP-nets) with three added features: first, there is a built-in type of real numbers; second, tokens can be forced to wait in places; third, an interface specifies how the Net can be externally supervised. Even if these added features also add complexity,...

Abstract: Aero-engines maintenance procedure can be treated as a typical discrete event dynamic system. A theory that synthesized timed colored Petri net is proposed. The theory adopts a bottom-up approach by merging all sub modules, and each one characterizes the critical resource contention among processes. Nevertheless Petri net seems inapplicable to dynamic scheduling modelling because of i...

In this paper, we develop a syntactical version of elaborated reductions for high-level Petri nets. These reductions simplify the model by merging some sequential transitions into an atomic one. Their conditions combine local structural ones (e.g. related to the actions of a thread) and global algebraic ones (e.g. related to the threads synchronization). We show that these conditions are perfor...

TCPNIA (Timed Colored Petri Nets with Inhibitor Arcs, TCPNIA) is a model for specifying real-time embedded systems. It integrates features of colored Petri nets, timed Petri nets and inhibitor arcs. The methods for modeling modules of systems using TCPNIA are proposed. A depth-first scheduling algorithm for TCPNIA is proposed. The system level resource’s influence to schedulable path is conside...

This paper presents and discusses an industrial production system model based on Colored Petri Nets. The model was developed in order to analyse the agent's behavior of a distributed multi-agent system oriented to the simulation of the management and control of a spe-ciic hardmetal production system plant. This eeort help us to create the basis to get a more robust system with means to resist b...
