英文摘要：

In order to improve the firing accuracy of multi-tube other weapons, through the analysis of the factors influencing the firing accuracy of multi-tube rocket, the composite optimization algorithm is adopted to improve the attack accuracy on the premise of not changing overall structure of the weapon launching system and the launching environment. Taking the firing intervals and sequence as the design variables, the optimization model is established for multi-tube rocket firing dispersion, the multi-tube rocket firing dispersion optimization method based on composite method is presented, which provides a reference for the optimization of multi-tube rocket firing accuracy. The optimization results show that the multi-tube rocket firing dispersion is significantly improved.
