Simulation: an interface between theory and practice, elucidated with a ships controllability study
bookPart
Often there is a wide gap between research on man-machine performance under real life conditions and research on control behaviour in a laboratory context. The present study
suggests to combine laboratory experiments within a strict axiomatic theoretical framework with less axiomatically constrained simulator experiments. Converging evidence from these two approaches should bridge the gap between the theoretical based laboratory experiment and the realism of the simulator experiment. The idea is elucidated with the description of two experiments. In the first experiment the hypothesis is tested whether ship handler's control behaviour is mainly based on one of two elements: preprogrammed control or feedback control. Notions on preprogrammed control are primarily based on stimulus-related control setting. Notions on feedback control are primarily based on the evaluation of correctness of performance. The second (simulator) experiment is aimed at differences between the controllability of pushtows on inland navigation channels as a function of ship traffic density. The traffic density is varied to discriminate between performance based either on preprogrammed or feedback control. Results will show some advantages of this paired experiment approach.
