Evaluation of Control Station Design: The Crew Human Engineering Software System

Abstract

Computer simulation techniques are an attractive adjunct to human-subjects testing in the evaluation of the interface between the operators of a complex machine and the control station at which they work. The Crew Human Engineering Software System (CHESS) brings together a powerful collection of tools for analyzing both control station geometry and procedure. These tools permit design evaluation to procede before construction begins, and allow the comparison of many alternative designs across a variety of operating conditions at minimal expense. CHESS has made an important contribution to the evaluation of aircraft flightdeck design at Boeing.
