Graphical control systems and multiple displays

Abstract Control systems are considered which require updating of a large number of graphics displays of system and subsystem configurations. All of the displays are to be updated and to be shown on a CRT screen upon user demand, within a limited time period. Many models for evaluating system performance are given for different hardware combinations. The problem was initially studied at the Goddard Space Flight Center of the National Aeronautics and Space Administration in Greenbelt, Maryland with regard to ground control systems for spacecraft.
