Abstract:

Aimed at the high cost of long-range precision-guided weapons and the limited number of weapon launch platforms in modern warfare, the multi-stage weapon target assignment(MS-WTA) problem is studied, and a mixed-integer nonlinear programming model is established to minimize the cost of weapons. A hybrid intelligent search algorithm integrating Hungarian and simulated annealing(HSA) is designed. Firstly, the hit stage and mark relaxation are determined according to the spatio-temporal state and damage characteristics of the target to be attacked. Under the framework of simulated annealing, the attack stage is adjusted based on the target's relaxation, and then the accurate matching scheme of weapons and targets in each stage is calculated by Hungarian algorithm. By combining heuristic algorithms and precise solving techniques, the calculation time is greatly reduced while ensuring the quality of the solution. Through computational experiments and comparative analysis with the variable neighborhood search algorithm, the effectiveness of this algorithm in solving MS-WTA problems is verified. The simulation results show that the proposed algorithm outperforms the variable neighborhood search algorithm in terms of computational time and solution performance.
