Abstract: To solve the problem that the current weapon target assignment scheme may be disturbed by uncertain factors in air defense operations in critical area at sea, a new dual target dynamic weapon target assignment model considering target interception probability and firing stability of air defense weapons is proposed. First, three uncertain factors are given according to the characteristics of air defense operations in critical area at sea. Then, a dual target optimization function of DWTA is constructed, and the related parameters defined. Later, the steps for solving the bi-objective optimization model are given. Lastly, an example is given to verify the proposed method. Through the analysis of simulation results, it is found that the model proposed in this paper can serve as a weapon target assignment scheme with high firing stability and high target interception efficiency. In the presence of uncertain factors, the model can provide a new reasonable weapon target assignment scheme in an appropriate period of time, which has a certain reference value for improving the operational efficiency of air defense weapons in critical area at sea.
