Abstract
When the earthquake disaster occurs, it is necessary to carry out the earthquake-damaged reservoir reinforcement work as soon as possible to avoid secondary disasters. Based on the improved entropy weight method to determine the evaluation index weight of earthquake-damaged reservoir, combined with the approximation ideal solution ranking method and grey correlation analysis method, the grey ideal value approximation model was constructed. The comprehensive value of reservoir and the reinforcement sequence were evaluated. The improved grey clustering method was used to compare and verify the accuracy of the model.
