This paper analyzed the characteristics of joint optimal scheduling system of cascade sluice stations in plain slope water area, and probed the reasonable joint optimization scheduling method, with a view to achieving the best social, economic, and ecological environmental benefits, and to providing a reference for the study of the joint optimal scheduling of a specific area and the formulation and implementation of the development plan of this area. We established a multi-objective joint optimal scheduling model for cascade sluice stations, and used NSGA-ò algorithm to obtain a non-inferior solution set, and then used the multi-attribute decision-making for optimum scheme selection. The Yellow River and its southern area in Suqian city were chosen for a case study . The results demonstrated that compared to conventional scheduling , the joint optimal scheduling could reduce the rate of water shortage and improve the water supply capacity of the system by increasing the quantity of water delivery, and meanwhile reduce the waste water, make full use of water resources, and save the cost of water supply. The results proved that the multi-objective optimal joint operation model and solution method of cascade sluice stations in plain slope water area are quite maneuverable and superior, with guiding significance and application value in practical engineering.
