Appraisal model of performance to field waterworks based on BP neural networks

Based on the researches of predecessors and in veiw of the needs of war and technology of purification,an index system of filed waterworks was offered and the appraisal model built with neural networks and a new algorithm presented in order to appraise the performance of field waterworks,and choose and purchase the best watercleaner conveniently.The appraisal results of five waterworks compared with those of the specialists prove that the model is credible and practical.This model can replace man and work as a computer-specialist. So this model can be used in purchasing waterworks for our troops, which makes buyers analyze and compare waterworks conveniently and choose good waterworks.
