| 摘要: |
| 多冲量最优交会问题是航天领域非常重要的一个研究方向，从运筹学角度将此问题转化为一个多阶段多维动态规划问题，并着重对多阶段二维动态规划进行分析研究。在给出状态方程及指标函数递推公式的基础上，得到了两冲量和三冲量交会问题最优解的求解算法，之后分别通过实例验证了算法的有效性。对于以地心角等参数为决策变量的更高维问题，讨论了利用进化算法等降维方法实现多维动态规划的思想。 |

| Abstract: |
| The multi-impulse rendezvous problem is a key research field of astronautics. Firstly, based on the operational research, this problem was converted to a multi-phase-multi- dimension dynamic programming question. Then the multi-phase-two-dimension dynamic programming problem was emphatically analyzed, and the state transfer equations and recursion equations of the performance function were deduced. The solution to the two-impulse and three-impulse problem and the validating examples were given later. ln the end, the dynamic programming idea which uses the evolution algorithm to reduce the dimension of the multi-dimension question was introduced. |
