By using the transfer matrix method of multibody system, the hard problem of computation of the vibration characteristics of LRMLRS coupled with rigid bodies and elastic bodies is solved which is very difficult to the ordinary dynamic methods, and the vibration characteristics of LRMLRS which is varied when the number of rockets in the launch device is varied, is obtained conveniently. By developing augmented eigenvectors of the LRMLRS and its orthogonality conditions, the nonorthogonality problem of the multibody system including rigid bodies and elastic bodies is solved and the exact analysis of the dynamics response of the LRMLRS including rigid bodies and elastic bodies is realized. By using the random integer programming method, the hard optimization problem which contains continuous variables, discrete variables and random variables at the same time is solved. This method provides a technology for optimum design with random variables and discrete variables. The dynamic optimum design is realized to decrease the number of rockets consumption in the LRMLRS test.

President Lin Chun-shin pointed out that there was a sound development in Scandinavian countries in such aspects as accumulation of wealth and education of talents. Taiwan should emulate these fine achievements. But in terms of the issue of sustainability, localization was stressed and copying indiscriminatingly was not advisable. So we needed to have top talents to make good use of knowledge-based development in order to effectively solve issues regarding the environment and tribal development, thus creating a bright future for posterity.
