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 Combined with the Yellow River mainstream reservoir joint scheduling, this paper discusses the scheduling objectives, flow time considerations, multi-year regulation of reservoir scheduling and other related issues based on the establishment of multi-objective reservoir optimization scheduling multi-model system; the application of large systems decomposition coordination principle , Proposed the goal, the model combination question and the corresponding decomposition coordination algorithm; and gave the detailed solution steps. The research shows that the multi-objective and multi-model proposed in this paper is of great significance and reference value to solve the joint regulation of large-scale reservoirs in complex river systems
