DATA ON THE USABILITY OF MICRO SAINT.

The human operator modeling and simulation system named Micro SAINT, is presented as a system which is easy to use by people with little or no experience in either computer simulation or computer programming. Several applications of Micro SAINT, which have involved modeling a variety of systems including large complex systems, relatively sophisticated technological systems, and multioperator systems, are described. In the course of these modeling efforts, the boundaries of the Micro SAINT modeling system have been explored.
