The authors consider the problem of developing a computer program to assist the aerospace psychologist in the task of assessing human performance reliability. The procedures which were developed permit an analysis of physiological and psychological variables relevant to human performance in space, the stressors that cause degradation in performance because they impair physiological and psychological functions, and the tasks that humans must perform. The degrading effect of each stressor is specified for each physiological and psychological variable, and the combined effect of all stressors on each variable is calculated. The status of all physiological and psychological variables relevant to the performance of a given task is assessed and a resultant reliability for each task is calculated. The minimum reliability within a given time period is used to produce a reliability profile. The system was used to obtain reliability ratings based on estimates of conditions for a hypothetical lunar mission.
