A case study of a human error in a dynamic environment

This joint project between C.E.N.A.(1), L.A.M.I.H.(2) and Percotec(3) consisted in evaluating various implementations of a principle of distribution of workload, called dynamic allocation of tasks, between air traffic controllers and an expert-system. Our work focuses on the analysis of a human error intervening during these simulations. We present this case study in order to highlight the specific difficulties encountered by operators in managing the temporal aspects of a dynamic environment, such as they were unveiled in the work of De Keyser [6] and relate it to Reason's [13] contribution exposed in his Generic Error Modelling System. in conclusion we emphasise some parts of this model that should be refined and enriched in order to encompass the temporal characteristics of dynamic environments.
