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 event | An event that occurs when a function is activated or deactivated. |
Activation/deactivation requirement | The activation or deactivation that one or more functions must satsify when specified events and conditions occur. |
Activation/deactivation rules | The logic which determines when one or more functions are activated and deactivated. |
Activation time | The interval of time that a function or state is active. |
Activity | One or more related actions. |
Analysis | The process of evaluating elements, properties and associated relationships. |
Analysis model | A 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 |
Behavior | The 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 allocation | The allocation of functions and/or states to systems, and the allocation of inputs and outputs to system ports. |
Boolean | Refer to UML specification |
Category | A partitioning of elements based on a classification. |
Complex number | A number which can includes a real and imaginary part. |
Component | A 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 function | A function which is decomposed into lower level functions. |
Composite state | A state which includes nested states. |
Concurrent state | A state which is active at the same time as another state that is part of the same composite state. |
Condition | An expression with a discrete output, which is true as long as the expression evaluates true, and is false otherwise. |
