Abstract:

The purpose of the technique is to allow prediction of system effectiveness while a system is in the early design stage andor comparative evaluation of alternative system designs. The model is based on the use of a digital computer which sequentially simulates operator performance of each subtask in a total task. As a result of various calculations, output records are obtained of subtask success or failure, task success or failure, peak stress, terminal stress, idle time, waiting time, team cohesiveness, and, in the event of successful task completion, time available but unspent. The method and results of applying the technique to an air intercept by a team composed of a pilot and a radar-observer are reported. No statistically significant differences were obtained between the predictions from the model and real life, outside criteria data for the same task. Generally, the results from the model were rational and conformed with expectancy. Author
