Behaviors of a given DEVS model is a set of sequences of timed events including null events, called event segments which make the model move one state to another within a set of legal states. To define this way, the concept of a set of illegal state as well a set of legal states are needed to be introduced. In addition, since the behaviors 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 (). In this article, we use a sub-class of General System formalism, called timed event system instead. Depending on how to define the total state and its external state transition function of DEVS, two ways to define the behavior of a DEVS model using Timed Event System. Since behavior of a coupled DEVS model is defined as an atomic DEVS model, behavior of coupled DEVS class is defined by timed event system. == View 1: total states = states * elapsed times == Suppose that a DEVS model, has # the external state transition . # the total state set where denotes elapsed time since last event and so For a total state at time and an event segment as follows. If unit event segment is the null event segment, i.e. If unit event segment is a timed event where the event is an input event , If unit event segment is a timed event where the event is an output event or the unobservable event , Computer algorithms to simulate this view of behavior are available at Simulation Algorithms for Atomic DEVS. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Behavior of DEVS」の詳細全文を読む スポンサード リンク
