Modelling human performance in supervisory control tasks

The current state of methodology for the development of large-scale, multioperator command and control systems, is largely an art. The designers formulate goals and system objectives. They examine the available technology and produce a conceptual design that specifies the roles of hardware, software, and human resources. They then proceed to build either a manned simulation of the basic design or a prototype system that can serve as a test bed for evaluating the approach and for exploring alternative implementations of the basic approach.
