FD-DEVS
FD-DEVS (Finite & Deterministic Discrete Event System Specification) is a formalism for modeling and analyzing discrete event dynamic systems in both simulation and verification ways. FD-DEVS also provides modular and hierarchical modeling features which have been inherited from Classic DEVS. History FD-DEVS was originally named as "Schedule-Controllable DEVS" wang05and designed to support verification analysis of its networks which had been an open problem of DEVS formalism for 30 years. In addition, it was also designated to resolve the so-called " OPNA" problem of SP-DEVS. From the viewpoint of Classic DEVS, FD-DEVS has three restrictions # finiteness of event sets and state set, # the lifespan of a state can be scheduled by a rational number or infinity, and # the internal schedule can be either preserved or updated by an input event. The third restriction can be also seen as a relaxation from SP-DEVS where the schedule is always preserved by any input events. Due to this ...

SP-DEVS
SP-DEVS abbreviating "Schedule-Preserving Discrete Event System Specification" is a formalism for modeling and analyzing discrete event systems in both simulation and verification ways. SP-DEVS also provides modular and hierarchical modeling features which have been inherited from the Classic DEVS. History SP-DEVS has been designed to support verification analysis of its networks by guaranteeing to obtain a finite-vertex reachability graph of the original networks, which had been an open problem of DEVS formalism for roughly 30 years. To get such a reachability graph of its networks, SP-DEVS has been imposed the three restrictions: # finiteness of event sets and state set, # the lifespan of a state can be scheduled by a rational number or infinity, and # preserving the internal schedule from any external events. Thus, SP-DEVS is a sub-class of both DEVS and FD-DEVS. These three restrictions lead that SP-DEVS class is closed under coupling even though the number of states are finite ...

Behavior Of Atomic DEVS
The behavior of a given DEVS model is a set of sequences of timed events including null events, called event segments, which make the model move from one state to another within a set of legal states. To define it this way, the concept of a set of illegal state as well a set of legal states needs to be introduced. In addition, since the behavior of a given DEVS model needs to define how the state transition change both when time is passed by and when an event occurs, it has been described by a much general formalism, called general system PK00 In this article, we use a sub-class of General System formalism, called timed event system instead. Depending on how the total state and the external state transition function of a DEVS model are defined, there are two ways to define the behavior of a DEVS model using Timed Event System. Since the behavior of a coupled DEVS model is defined as an atomic DEVS model, the behavior of coupled DEVS class is also defined by timed event syste ...

Discrete Event Dynamic System
In control engineering, a discrete-event dynamic system (DEDS) is a discrete-state, event-driven system of which the state evolution depends entirely on the occurrence of asynchronous discrete events over time. Although similar to continuous-variable dynamic systems (CVDS), DEDS consists solely of discrete state spaces and event-driven state transition mechanisms. Topics in DEDS include: * Automata theory * Supervisory control theory * Petri net theory * Discrete event system specification * Boolean differential calculus * Markov chain * Queueing theory * Discrete-event simulation * Concurrent estimation References * * * {{cite book , author-last1=Kumar , author-first1=Ratnesh , author-last2=Garg , author-first2=Vijay K. , date=1995 , title=Modeling and Control of Logical Discrete Event Systems , publisher=Springer Springer or springers may refer to: Publishers * Springer Science+Business Media, aka Springer International Publishing, a worldwide publishing group founded ...

Directed Acyclic Graph
In mathematics, particularly graph theory, and computer science, a directed acyclic graph (DAG) is a directed graph with no directed cycles. That is, it consists of vertices and edges (also called ''arcs''), with each edge directed from one vertex to another, such that following those directions will never form a closed loop. A directed graph is a DAG if and only if it can be topologically ordered, by arranging the vertices as a linear ordering that is consistent with all edge directions. DAGs have numerous scientific and computational applications, ranging from biology (evolution, family trees, epidemiology) to information science (citation networks) to computation (scheduling). Directed acyclic graphs are sometimes instead called acyclic directed graphs or acyclic digraphs. Definitions A graph is formed by vertices and by edges connecting pairs of vertices, where the vertices can be any kind of object that is connected in pairs by edges. In the case of a directed graph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strongly Connected Component
In the mathematical theory of directed graphs, a graph is said to be strongly connected if every vertex is reachable from every other vertex. The strongly connected components of an arbitrary directed graph form a partition into subgraphs that are themselves strongly connected. It is possible to test the strong connectivity of a graph, or to find its strongly connected components, in linear time (that is, Θ(''V'' + ''E'')). Definitions A directed graph is called strongly connected if there is a path in each direction between each pair of vertices of the graph. That is, a path exists from the first vertex in the pair to the second, and another path exists from the second vertex to the first. In a directed graph ''G'' that may not itself be strongly connected, a pair of vertices ''u'' and ''v'' are said to be strongly connected to each other if there is a path in each direction between them. The binary relation of being strongly connected is an equivalence relatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
