B-P人工神经网络模型在纯净水安全评价中的应用

he artificial neural network have characteristics that it has a strong power to be self-organizing, self-learning and self-adapting.At the same time ,it is not only able to output nonlinear mapping but also easy to learn and train.As a result,it’s widely applied in various study fields.In this paper,we use these characteristics to make a evaluation and sorting on a random inspection in nine pure water production and sales company in a city. Through setting the water safety level,we finally calculate every batch’s safety level and sort all the batchs. Combined with actual situation, this model gives pretty good results.
