The components don't necessarily receive the same input or generate the same output. The components are analytically redundant , meaning they are redundant with respect to the general effect their output has in controlling their environment, but not necessarily redundant in their implementation, the algorithms used, or the output produced. The Simplex Architectural Style Figures in this file are displayed in a separate browser window.

All components execute concurrently.
The leader's output is used if it passes the acceptance test applied by the decision and switch unit. The acceptance test is based on a model of the controlled environment and the ability of the safety component to recover from actions of the other components. Note that the decision and switch component receives a copy of the input and uses it as a basis for performing its acceptance test. The Simplex style assumes that mechanisms exist to bound the execution time of the components, thereby preventing timing overruns. Another ABAS should address these performance issues.
