Abstract:

This paper presents a ground combat Weapon Target Assignment (WTA) model that enhances the validity of firepower allocation for ground units. The model incorporates shooting effectiveness as a key factor and formulates an optimization function considering the benefits and costs of attack decisions on the battlefield. By assessing the threat level of targets, the model determines the urgency and necessity of an attack. By evaluating the battlefield value of targets, it calculates the threat reduction value. The model predicts enemy attack plans and estimates weapon losses based on the probability of damage inflicted by targets. It quantifies the value of ammunition by comparing forces with ammunition reserves. By analyzing the tactical intentions of both sides, the necessity of a strike is weighed against the cost of tactical intent exposure. To solve that WTA model, an improved artificial bee colony algorithm is proposed. This algorithm improves the search directionality of the algorithm and the ability to escape local optimum at the end of each iteration. At the same time, a population initialization strategy based on the Weapon Target Combination Library is adopted to improve the initial population quality of the algorithm. Simulation examples show the soundness of the proposed model and the advantages of the improved algorithm in terms of convergence speed, convergence accuracy, and robustness.
