According to the idea of "dynamic and static combination" in dynamic weapon-target assignment problem

aiming at the first phase of the cooperative air combat

while giving the targets the most damage effect at the same time

trying to save weapon resources as far as possible.In response to the next phase of fire distribution

based on coarse granularity parallel strategy and using OpenMP parallel optimization technique

cyclic iteration and cyclic assignment

which is the main time-consuming part of ant colony system are taken

into parallel processing.Through the simulation of various fire allocation problem

verify the proposed weapon-target assignment model is reasonable

and the parallel ant colony algorithm is effective.
