Threat Evaluation of Air Targets Based on the Generalized λ-Shapley Choquet Integral of GIFSS

Fast and accurate threat evaluation (TE) of incoming air targets has a great influence on defense. In this paper, two new generalized intuitionistic fuzzy soft set (GIFSS) methods are proposed for targets. Firstly, the index system is reasonably constructed by analyzing relative kinematics between assets, apart from that interceptors, which more reasonable practical. Secondly, after indexes (TI) properly obtained, aggregation operators GIFSS put forward based λ-Shapley Choquet integral. The not only depict correlations among but also consider importance them globally. Finally, effectiveness superiority verified through numerical simulation including four in different systems.
