摘　　要：针对带有性能约束的卫星舱布局优化问题,依据不干涉理论,给出了计算机上易于实现的、能计算图元之间干涉量的不干涉算法.采用实数编码等策略对布局优化问题构造了改进遗传算法.数值结果表明:该算法在解决带有性能约束的布局优化问题时大大减少了计算时间,提高了计算精度.To solve the optimal problem of layout for artificial satellite module with performance constraints, a non-overlapping algorithm which is easy to be realized on computer and can compute the equilibrium of paces is proposed based on the non-overlapping theory. The improved GA for the optimal problem of layout is constructed adopting the real number code strategy. The numerical results show that the proposed algorithm can greatly cut down the running time and improve the computing accuracy when it is used to solve the optimal problem of layout with performance constraints.
