Abstract: Modelling and simulation is increasingly being used to represent occupant behaviour of human subjects and anthropomorphic test devices. Future trends are towards the application of certification by analysis whereby a product, such as an aircraft seat, can be partially certified through analytical means. A robust and objective method to discriminate different features of the model comparison is needed to determine model validity so that the certification authority can objectively determine the model acceptability. Expert opinion could introduce bias and lead to inconsistent results. In any testing, there is some inherent uncertainty and variation in the measured responses that affects the baseline comparison data. Each individual response should be treated as a separate case. A method derived from Sprague and Geers was developed and applied to occupant models of seat simulations. Using test data, acceptable error levels were calculated that represent the occupant and provide consistent and objective results.
