The role of the human operator in control systems is evolving towards that of a supervisor who plans sequences, and monitors and away from strictly tracking. New modeling approaches and techniques are required to realistically represent and examine these new system configurations and resulting performance issues. This dissertation study proposed an alternate modeling approach comprised of discrete network models in combination with elements of an open-loop optimal control model formulation. The feasibility of employing this combined modeling approach was demonstrated through its application to the DAIS Digital Avionics Information System system in which pilot duties involve information retrieval and cognitive processing tasks in addition to flight control.
