PPE Model Based on RAGA and Its Application to Comprehensive Evaluating of Groundwater Quality

Abstract

In view of the independence and disagreement of each index in the groundwater quality evaluating, projection pursuit evaluating model is applied to groundwater quality evaluation, and real coding based accelerating genetic algorithm is introduced to optimize the projection direction so that multi-dimension data can be turned into low dimension space. The value of projection function can be calculated by way of seeking the optimal projection direction, thereby, according to the value, comprehensive evaluation of soil quality can be process. This paper provides us with a new way to groundwater quality evaluating, the outcomes of application in handan city shows that it is feasible and reasonable.
