多目标多年调节水库余留期效益函数探讨

Return functions of remaining stages for multi-objective and over-year storage reservoirs

本文研究了随机环境下多目标多年调节水库的优化调度问题．用参数迭代法逼近余留期效益函数，在一定程度上可以通过调整余留期的长短及各用水部门单价比的办法，使城镇供水及灌溉用水保证率达到规定要求，为指导这类水库的运行作了大胆而有益的探索．实例研究表明，成果令人满意．

This paper deals with optimal operation problem of multi--objective and overbear storage reservoir under stochastic condition. The parameter iteration method is used to solve the return functions of remaining stages. It is testified that a reliable municipal water supply and rural irrigation could be ensured by adjusting the duration of remaining stages and rating the appropriate unit prices of water for different usages. Practical application of this method is presented and .the results are reasonable.
