Abstract : A stochastic, digital computer simulation model was previously derived for and applied to the problem of simulating one or two-operator manmachine systems. Further test of the validity of the model through comparisons of the model's predictions of team performance with the actual performance of trained teams on a man-machine task is described. A complex two-operator manmachine equipment task involving team and individual branching, operator stress build-up, looping, cooperative work, communication, waiting, etc., was developed. The task was performed by two-man operator teams. This same task was inserted into the high speed computer programmed in accordance with the model. On the basis of non-statistically significant differences, in nine of ten possible comparisons, between the task success proportions actually achieved by the laboratory teams and the model's predictions of these proportions and on the basis of an arithmetic mean difference of four per cent between the actual and predicted times for task performance, it was concluded that support is gained for a contention favoring the validity of the model.
