Aiming at subjective weight determination of warship formation in overthehorizon antimissile threat estimationwe established a threat estimation index systemand built up the optimal index subjective weight determination models of linguistic typeutility typeorder relationship typefuzzy preference relationship typemultiplicative preference relationship type and interval utility type information given by the experts.The subjective weight determination was then transformed into a multiobjective constraint problemand the normalization coefficients for the index weight information matrices were obtained.Thenlinear weighting method was used to turn it into single objective constraint modelsand the index subjective weights were obtained.A numerical example was given to illustrate the method.The result demonstrates that this method can concentrate multitype index weight informationand can obtain warship formation overthehorizon antimissile threat estimation index subjective weight precisely.The method is easy for engineering realizationand provides a theoretical support for the design of overthehorizonantimissileassistant decisionmaking system for warship formation.
