Transfer matrix method for multibody system (MSTMM) is a new and efficient method for multibody system dynamics (MSD) developed in recent 20 years. Based on many advantages of MSTMM in studying MSD, the dynamics model and the dynamics simulation system for multiple launch rockets system (MLRS) are established. Joint optimization variables of firing orders and firing intervals are presented, combining with the Genetic Algorithms, the optimal design with the purpose of the best firing dispersion of MLRS is implemented. The optimal scheme is got and the firing dispersion has been increased 32.3%. Optimal design of firing orders and firing intervals is a low-cost and efficient way to improve the firing dispersion of MLRS.

Keywords:Multiple launch rockets system (MLRS); Multibody system dynamics (MSD); Transfer matrix method for multibody system (MSTMM); Genetic Algorithms; firing orders; firing intervals
