已有的水库供水调度规则研究偏重于单一目标供水,对于有着不同优先级和保证率的多个供水目标的研究不足。设计了一种水库多目标供水的调度规则,该规则能分别处理不同的供水目标,保证各项用水不发生深度破坏,在此基础上寻求累积缺水最小的调度目标。一种混合模拟和遗传算法的模型被用来对该规则的参数进行优化,在搜索规则最优参数组合的过程中遗传算法显示出很好的优化性能。实例研究检验了提出的供水调度规则的合理性。

The existing reservoir water-supply operation rules focuses on the single water supply, paying little attention to multipurpose water supply with different priority and reliability. This paper proposes a reservoir operating rule for the multipurpose water supply, which can deal with the different water supply respectively, make sure no severe shortfall happens and achieve the operating objective of minimizing the total water-supply shortage. A model combining simulation and genetic algorithm is used to optimize the parameters of the proposed operation rule, and the genetic algorithm is proved to give good performance in searching the optimal parameter combination. The case study justifies this operating rule for multipurpose water supply.
