In order to solve the problem about shortage of water resources in some areas and improve the utilization rate of water resources, this article focuses on a method of multi-dimensional allocation for water resources in Weihe basin based on fuzzy optimization. Firstly, a fuzzy optimization model was built. After considering the fuzziness and relativity of optimization, the membership degree of the optimal scheme was obtained by reasonable calculation, so that the simulation degree and reliability of model was improved. According to the model and actual situation of water resources in Weihe basin, the objective function and various constraints were obtained, so as to effectively control the mining yield of water resources. On this basis, TOPSIS was used to establish a new comprehensive benefit objective function. Finally, the optimal multi-dimensional allocation scheme of water resources was completed. Simulation results show that the proposed method can effectively complete the multi-dimensional allocation of water resources in Weihe basin. Meanwhile, this method has higher practicability, reliability and efficiency than other methods.
