Fidelity considerations for civil aviation distributed simulations
conference paper
The technical capability to network together simulators for al kinds of applications has already been proven. There are, however, still many unresolved issues regarding the ability of simulations to interoperate in a logically meaningful manner. One of the major concerns in development and validation of distributed simulations is the capability to qualify and quantify the 'over-all' simulation fidelity. In order to properly apply distributed simulations to civil aviation applications, such capabilities are mandatory. Therefore, the Delft University of Technology, in co-operation with the Netherlands Organization for Applied Scientific Research, started a fundamental research program on fidelity assessment methodologies for distributed simulations. This paper presents the results of a literature survey into fidelity research, and our approach to managing simulation fidelity. Amongst other things, the survey showed a lack of formal definitions and objective fidelity quantification practices. Here a preliminary fidelity theory is developed, which underlies our evolving 'Fidelity Management Overlay' (FiMO) process model. The FiMO provides a structured approach for the specification of fidelity characterizations, their quantification where possible, and the transformation of fidelity characterizations during the whole development trajectory of HLA-based simulations. The theory is illustrated with examples from a recently developed distributed 'Free Flight' simulation. © 2000 by Delft University of Technology.
