Multi-platform weapon target allocation method based on symbiotic search biogeography optimization

The invention provides a multi-platform weapon target allocation method based on symbiotic search biogeography optimization. The method comprises the following steps: constructing a multi-platform WTA model based on a fuzzy expectation effect; setting a population scale, and randomly generating an initial solution; encoding the population by adopting an integer-based matrix encoding strategy; calculating an objective function value corresponding to each solution, sorting the objective function values from large to small, and reserving the solutions corresponding to the first q larger objective function values; the initial population is optimized, and the randomness of the initial population is reduced; improving a migration operator, and carrying out migration optimization operation; a symbiotic mutation operator is provided, and mutation optimization operation is carried out; recalculating the objective function value corresponding to each solution, sorting from large to small, and replacing the solutions co
