文摘:与确定型优化调度将入流作为已知系列相比，随机动态规划将入流描述为随机变量，则更具合理性，因此该法是目前求解多库优化调度的最好方法.由于入流的随机描述，极大地增加了计算量，从而经常导致“维数灾”问题，故而又限制了该法在实际中的应用.本文以黄河上游5个梯级水电站群为例，应用随机优化调度方法研究其兴利优化调度问题，通过合理的入流描述，有效地避免了“维数灾”问题. |

文摘:高级综合结果中常量元件和输出悬空端口导致门级工艺映射结果中存在显式冗余.显式冗余无助于提高电路性能，反而增加功耗，降低电路的可测试性，使电路面积增大，应予消除.文中提出了显式冗余的队列循环优化算法，完全消除了此类冗余，从而有效地减少了生成电路的基片面积，提高了电路的可测试性. |
