There are different approaches to achieving persistence in system safety functions in the face of disturbances. Whereas some systems strive towards only maintaining stability of one stable state of maximum performance; other systems also rely on resilience; on the ability to make transitions to other stable states; of lower performance; when facing changes to driving variables or state variables. We discuss three kinds of systems; stable; bi-stable; and multi-stable systems; and their persistence when facing regular; irregular; and unexampled events.
