Abstract: Mine support equipment is a complicated multiobjective optimization problem, the traditional method is very difficult to find the optimal solution. The paper built a new simple and intuitive framework for the multi-objective problem of multidisciplinary design optimization in parallel based on collaborative genetic algorithm, which can connect the various disciplines and the adaptation degree function can reflect mutual influence between disciplines. At the same time, as a basic algorithm, the cooperative genetic algorithm can also effectively avoid premature convergence and obtain optimal solution well distributed. Results are greatly improved compared with the traditional algorithm.v
