ABSTRACT
Computer simulations of humans and machines interacting in work situations are increasingly being used in a variety of ways. They are beginning to take on a larger role in the exploration and evaluation of new operational concepts in business and business markets; to help develop and hone human skills under complex, extreme, and hazardous work situations; and to investigate the design implications of advanced technologies and their interactions with humans in complex, often open-ended work situations. To support these advances in computer simulations, corresponding advances are needed in modeling the work knowledge, skills, and abilities of software actors who serve as human surrogates in these increasingly complex simulated environments.
