A model, which had a9 its aim tho simulation of one or two oporator man-machino Bystems, is presented and discussed. Tho purpose of the tochnique is to allow prediction of Bystom offoctivonoss during the early design stage and to enable the comparative evaluation of alternative system dosigna. The modol is based on the use of a digital computer which sequentially simulates operator performance of oach subtask in a total task. As a result of calculations, output records are obtained for such items aa task success or failure, operator stress conditions, idle time, team cohesivonoss, and, in the ovent of sueeossful task completion, time available but unspent. The model was applied to tho simulation of two tasks. Tho first is tho in-flight refuolling of an F8U receiver aircraft by an A4D tanker aircraft; the second is an attack manoouvre by an advanced supersonic aircraft. Tho rosults from the model as reflected through tho digital simulation were compared with empirical critorion data obtained for both tasks and were further evaluated on the basis of their compatibility with logical expectation. Tho rosults from these initial applications of the model, which are summarized and evaluated, appear to conform with actual observations and are generally reasonable
