Abstract: To improve the efficiency of the airground integrated operation and the availability of the armaments, attack task decision-making of the airground multi-mission integrated missile is studied. An online assessment system of the missile-target relative status in the integrated operation is established firstly. According to the real-time assessment result, an attack task decision-making system is created to study the optimal algorithm of the task-switching decision-making when the missile fails to hit the original target effectively. The mode of air/ground task type switching decision-making is proposed based on the support vector machine to predict the decision of the next attack task type. And the mode of task number switching decision-making is proposed based on the Skyline query algorithm to find the non-inferior solutions set of targets. The relevant simulation is carried out and the result shows that the established system can adapt to the integrated operation superior than other traditional methods to make the attack task decision correctly.
