Research on Forepart Evaluation for Support Concept of the Winged Missile Based on Vague Sets

Definition of the evaluation for support concept of the winged missile was analyzed. And aiming at the characteristic of the forepart evaluation, the index system of the forepart evaluation was established. 3-D meaning of subordinative degree and expression of Euclidean distance on Vague sets were described, and a new decision method based on similarity measures between Vague sets was proposed. During the forepart evaluation for support concept, the larger the value of similarity measures is, the closer the degree between alternative concept and desired concept is. Finally, feasibility and rationality of similarity measures of Vague sets in the forepart evaluation for support concept of the winged missile is demonstrated through an illustration.
