Multi Target Threat Assessment Method Based on Improved Dual Variable Weight

摘要

Aiming at the problem that it is difficult to determine the threat degree of multiple attacking targets in battlefield environment, an improved multi-target threat assessment method with double variable weights is proposed. Firstly, AHP and improved entropy weight method are used to calculate the subjective and objective weights respectively to obtain the first weight; then, a comprehensive equilibrium function is constructed, which integrates the variable weight theory and the first weight as the final weight; finally, the ideal solution and grey correlation method are improved and reorganized to obtain the multi-target threat assessment results. The simulation results show that the proposed method is more in line with the actual situation by synthesizing the subjective and objective factors of the index and the influence of the change of the state value on the weight change; the ranking results comprehensively test the distance and shape changes between the indicators, and the comparison results with other methods also show the effectiveness of the proposed method.
