Abstract

Two general factors relevant to human performance in man-machine system were subjected to experimental analysis: (a) the influence of task load on operator capacity and (b) the effects of situational constraints on operator adaptability. Four variables, traffic input rate, control zone area, control team organization, and arrival sequencing procedures, were manipulated. Results from the observation of six 2-man teams indicated that physically defined constraints were more detrimental than those imposed by rules or organization structure. Procedures intended to enhance performance which depend on operator predictions or anticipations were observed to have a limited utility. Under high load stress, operator's actions seemed entirely determined by the immediate circumstances.
