Simulation Model
An ADAS model consisted of nodes connected by directed arcs.
For abstract simulation a node represents a process (systems engineering) in the system that you are modeling. The readiness for execution or firing of this process requires that: its inputs are satisfied, space is available for its outputs, and its shared resource/hardware is available. During execution the node consumes its inputs, uses the resource for the prescribed duration, then produces its outputs.
The inputs and outputs of a process are represented by discrete tokens. These tokens flow along the arcs in the graph. If the maximum arc size is greater that one, then an arc would represent a buffer between system processes.
To refine the model of the system, a subgraph could be placed below the node to refine the behavior of that process.
Physical and behavioral properties were attached to nodes and arcs in the form of attributes. The attribute definition language allowed the computation of attributes from ancestor attributes and global values.

Famous quotes containing the words simulation and/or model:
“Life, as the most ancient of all metaphors insists, is a journey; and the travel book, in its deceptive simulation of the journey’s fits and starts, rehearses life’s own fragmentation. More even than the novel, it embraces the contingency of things.”
—Jonathan Raban (b. 1942)
“Research shows clearly that parents who have modeled nurturant, reassuring responses to infants’ fears and distress by soothing words and stroking gentleness have toddlers who already can stroke a crying child’s hair. Toddlers whose special adults model kindliness will even pick up a cookie dropped from a peer’s high chair and return it to the crying peer rather than eat it themselves!”
—Alice Sterling Honig (20th century)
