- Abstract:
- At present, the design of rainwater storage facilities lacks integrated analysis of inflow regulation during actual operation, leading to the role of rainwater storage facilities cannot be fully reflected in the simulation of the design scheme. The total overflow, cost and cost performance were selected as the optimization objectives, the design parameters and scheduling parameters of rainwater storage facilities were regarded as the decision variables, and the multi-objective optimization algorithm was applied to drive the SWMM model to determine the best design scheme. Combined with actual cases, awGA (adaptive weight genetic algorithm), NSGA-Ⅱ (non-dominated sorting genetic algorithm Ⅱ) and NSGA-Ⅲ (non-dominated sorting genetic algorithm Ⅲ) were tested respectively, and the adaptability of each algorithm for multi-objective optimization of rainwater storage facilities was analyzed. The comparison test showed that the multi-objective optimization method integrating inflow regulation could fully reflect the potential of large and medium?sized rainwater storage facilities to alleviate regional waterlogging situation through flexible regulation. In addition, the established cost performance function could quickly identify the scheme with outstanding benefits.
