The joint optimal operation of multi-source gate-dam groups is the key to balance multiple objectives like water level, water quality, water efficiency, and costs in water network scheduling. This study focuses on the cascade scheduling system of the Suqian Yellow River Old Course. Considering water level control, water quality compliance, cost reduction, and efficiency improvement, a multi-source gate-dam joint scheduling optimization model was established by coupling a hydrodynamic-water quality model with the NSGA-Ⅱ algorithm. Using the mechanism of "scheme generation-process simulation-effect evaluation-feedback optimization", the Pareto optimal solution set was iteratively solved. The comprehensive optimal scheduling solution was determined by the entropy weight method. The results show that the significant multi-objective conflicts among water level, water quality, efficiency, and cost in the study area; The cost and efficiency are inversely constrained; The relationship between water quality and water level is non-monotonic; There is a positive synergy interval between efficiency and water level; The cost and water quality mutually restrict each other; The proposed model can effectively balance these four objectives, with the comprehensive optimal solution yielding values of 0, 0.09, 0.24, and 0.12, respectively, achieving integrated optimization compared to single-objective solutions. The proposed method can provide crucial support for solving optimal scheduling problems involving multiple water sources, projects, and objectives.
