Research and Application of Warship Multiattribute Threat Assessment Based on Improved TOPSIS Gray Association Analysis

Multitarget threat evaluation of warship air attacks is one the most urgent problems in defense operations. To evaluate target quickly and accurately, an attack multitarget method based on improved TOPSIS gray relational analysis proposed. This establishes assessment system five attributes type, anti-jamming ability, heading angle, altitude, speed. The weight coefficient each index obtained by combining entropy with analytic hierarchy process. Topsis can make full use information original data, its results accurately reflect gap between various schemes. weighted Mahalanobis distance comprehensive correlation attribute to be evaluated positive negative ideal states are calculated method. degree two methods. Finally, example given prove effectiveness model.
