Abstract:

The information-gap model which represents the uncertainty of hypergame outcome preference perception is established and the robustness analysis of equilibrium outcomes of hypergame is discussed. For a given uncertainty parameter, by iteratively defining a sequence of sets of preference vectors which are successively further from the nominal preference perception vector, the information-gap model for hypergame preference perception is designed. The robustness of equilibrium outcomes of hypergame is analyzed based on the information-gap model by determining the greatest value of the uncertainty parameter for which the set of equilibrium solutions is the same as the nominal equilibrium set. A military example illustrates the proposed method at the end.
