SECM Concept Model Definitions Snapshot (1/28/2016)


Name Documentation
Action A non-interruptible function. Note: An action represents an atomic unit of processing or work. Actions may be continuous or discrete. Discrete actions may or may not be assumed to execute in zero time.
Activation/deactivation eventAn event that occurs when a function is activated or deactivated.
Activation/deactivation requirementThe activation or deactivation that one or more functions must satsify when specified events and conditions occur.
Activation/deactivation rulesThe logic which determines when one or more functions are activated and deactivated.
Activation timeThe interval of time that a function or state is active.
ActivityOne or more related actions.
AnalysisThe process of evaluating elements, properties and associated relationships.
Analysis modelA model used to analyze the structure, behavior, and/or properties of systems and environments.
AP-233 ISO STEP Application Protocol for Systems Engineering Data Interchange Standard
Arc An association between two or more nodes.
Association Refer to UML specification
BehaviorThe activation/deactivation of one or more functions. Note: This describes how a system interacts with its environment. Reactive behavior includes the stimulus and response.
Behavior allocationThe allocation of functions and/or states to systems, and the allocation of inputs and outputs to system ports.
BooleanRefer to UML specification
CategoryA partitioning of elements based on a classification.
Complex numberA number which can includes a real and imaginary part.
ComponentA constituent part of an element or system that contributes to the properties and behaviors of the whole (emergent). Note: A leaf component does not have constituent parts.
Composite functionA function which is decomposed into lower level functions.
Composite stateA state which includes nested states.
Concurrent stateA state which is active at the same time as another state that is part of the same composite state.
ConditionAn expression with a discrete output, which is true as long as the expression evaluates true, and is false otherwise.
