Abstract:

System optimization is one of the core issues in the research of the weapon equipment systems. However, to overcome the low efficiency and high cost of the optimization methods of equipment systems based on simulation, an optimization algorithm of weapon equipment systems based on the Kriging surrogate model and uniform design is presented, in which the surrogate model is updated by the EI（expected improvement） function, and the steepest descent method is used in the optimization algorithm. The optimization algorithm put forward in this paper has high precision and high speed of convergence, and also has a high theoretical and practical value in solving nonliner problems.
