Abstract�� A multi-tier trajectory optimization framework for a surface-to-air missile to optimize the kill probability was proposed based on the multi-tier optimization process(MTOP). The missile-s intercepting process was divided into three tiers, which were the midcourse trajectory optimization, the terminal homing phase and the kinetic tungsten rods lethal enhance kinetic kill process. A tier can be seen as a subsystem, the multi-tier trajectory optimization problem is essential a multidisciplinary design optimization (MDO) problem. A solution of the multi-tier trajectory optimization framework was presented based on the MDO theory and methods through discipline analysis and system analysis. The global sensitivity equation (GSE) method and All-in-One method were used to solve the system optimization problem. The results show that both methods are effective for solving the MTOP problem, and the All-in-One is much better.
