Water quality evaluation based on fuzzy artificial neural network

The artificial neural network(ANN) and the fuzzy recognition(FR) are all information process systems to simulate biological mechanism.And the two theories are widely applied to many fields currently.Taking each strong point into consideration,this paper proposes a fuzzy artificial neural network recognition model(FANNR) combining ANN and FR; thereby,the flexible recognition ability of the network is enhanced.Finally,the model is used to evaluate the water quality of the Tuo river,and the result shows that FANNR model is objective and practicable.
