Application of Improved Entropy Weight TOPSIS Model in Optimization of Rural Sewage Treatment Technology
The optimization of rural sewage treatment technology is the basis for the protection of rural ecological environment.According to the multi-attributes and multi-indexes feature of rural sewage treatment technology,this paper uses subjective weight(AHP method)and objective weight(entropy value method)to determine combinatorial weights to overcome the influence of subjective factors,and sets up the improved entropy weight TOPSIS model,which is applied to the optimization of five common rural sewage treatment technologies.The results show that calculation of this model is simple,the results are objective,and the model can serve as the decision analysis tool for the demonstration and promotion of sewage treatment technology in rural areas.
