Worker Performance in a Combined Manual and Decision Task under Different Work‐loads Available to Purchase

Industrial control tasks can also be called Combined Manual and Decision Tasks (CMDT). It is in the performance of such tasks that the human operator is likely to play an essential role as a decision maker. The findings presented are based on experimental studies in which 20 male subjects performed partial factorial experiments. Models of human performance in a two‐stage CMDT are developed and optimal conditions determined.
