Engineering today's highly complex real-time systems in uncertain environments requires new approaches. NECSI complex systems engineering research differs from traditional systems engineering by focusing on the roles of interdependence and evolution to create a process whereby local actions can build on each other to create a functioning system.

 

From Engineering to Evolution

NECSI has demonstrated the breakdown of conventional top-down engineering and that reliable complex systems can only be made by evolutionary dynamics and distributed collaborative design.
