- W2369876890 abstract "Based on the projection pursuit classification model,a comprehensive performance evaluation method of water using association(WUA) is established in this paper,which turns multi-dimensional data into low-dimensional space and calculates the value of projection function through the real coding based on accelerating genetic algorithm to optimize the best projective direction,then uses the optimal dissection method to conduct clustering analysis.Taking 42 Water Using Associations of Zhanghe Irrigation Scheme in Hubei Province as an example to conduct the comprehensive evaluation,the performance level of every association is determined according to the projection pursuit classification model and the value of projection function,then the associations are objectively divided into five ranks using the optimal dissection clustering analysis,namely excellent,good,middling,bad and worse.Meanwhile each evaluating indicator to the impacting level of the performance evaluation of water using association is analyzed according to the best projective direction.The evaluation results show that 50% of WUA is beyond the rank of good and more than 75% is beyond the rank of middling.This shows that the whole performance of WUA in Zhanghe Irrigation Scheme is good." @default.
