Model-Based Engineering with AADL: An Introduction to the SAE Architecture Analysis & Design Language

Chapter 9. Static and Dynamic Architecture

Systems have a static and a dynamic architecture. The static architecture is represented by a collection of components that are structured in a component hierarchy. For each component in the hierarchy, its component implementation defines the internal structure in terms of subcomponents and interactions in terms of connections. The dynamic architecture is represented by a collection of component and connection configurations that are controlled by modes. Modes effectively represent operational modes and fault tolerant configurations of both software and hardware, as well as modal behavior of individual components. In this chapter, we discuss subcomponents and arrays of subcomponents to represent the ...
