结合黄河干流水库联合调度，本文在探讨了调度目标选取、流达时间考虑、多年调节水库调度特点等有关问题的基础上，建立了水库优化调度的多目标多模型系统；应用大系统分解协调原理，提出了目标、模型组合问题及相应的分解协调算法；并给出详细的求解步骤。研究表明，文中提出的多目标多模型及算法对解决复杂河流大系统的水库联合调度具有重要意义和参考价值.

According to the joint reservoir operation for the Yellow Main Stream, the paper chooses the multi purpose, and establishes the multi model, with the decomposition and coordination algorithm of large scale system to solve.Then combinatoral problems of purposes and models, and the calculating method are presented to meet the needs of real reservoir operation. The research shows that it will be guadding significant and consulting valuble to the problem of joint reservoir operation in complex and large scale system for river.
