Problems solved by technology

[0003] The inventors found that the existing multi-objective optimization methods for water resources do not consider comprehensive factors, and the solution process is often to transform the objective function into a single-objective model with simple linear weighting, resulting in low precision of the optimization results, and cannot be used for the actual The optimal allocation of water resources should be used to guide the optimal allocation of water resources; the optimal allocation model of water resources should not only consider various water supply sources such as surface water, groundwater, and externally transferred water, but also take into account the types of water users in different regions and industries. In different scenarios, such as years with extremely low water conditions and extremely dry years, it is a multi-objective optimization problem for a complex natural-society system, in coordination with the relationship between economy-society-ecology. Therefore, there is an urgent need for a high-precision Multi-objective, multi-source and multi-user water resources optimal allocation method

Abstract

The present disclosure provides a method for optimal allocation of water resources based on a genetic algorithm. The scheme normalizes economic goals, social goals and ecological goals, so that each goal is weighted and calculated under the same dimension condition, and normalized After optimization, the weight of each objective has more practical significance; at the same time, the water resource optimization model constructed has the characteristics of multi-variable, multi-objective, and multi-constraint. The solution method has great advantages in calculation speed, accuracy, convergence, adaptability and portability.
