The Hughes Design Analysis System and Instructor Workload in Operational Trainers

Abstract

Computerized simulator trainers require varying degrees of instructor participation in training exercises and student performance evaluation. An estimation of instructor workload before the system has been fully developed is essential for an effective functional allocation of human and computer capabilities. One approach for estimating operator workload is simulation. The Hughes Design Analysis System (DAS) is an interactive and graphic simulation package. The present paper describes: (1) how DAS has been used for an instructor workload analysis, (2) the analysis method, (3) the results, and (4) the recommendations given to system designers.
