Abstract:

To execute the validation of simulation model objectively and reduce the risk in application of grey relational analysis (GRA) effectively, the methodology of improved GRA is proposed. To solve the problems existed in model validation based on current GRA methods, in view of the similarity and nearness between the simulation and flighttest time series (timevaring data), the improved GRA model is established. And it is proved that the improved model satisfies the four grey relational axioms. Finally, a case study is given to show the reasonability and validity of the improved model.
