Based on the operation data from a certain wastewater treatment plant(WWTP) in northeast China,the models of back propagation neural network ( BP NN ) and radial basis function neural network ( RBF NN ) have been designed respectively and the ability of convergence and generalization has been analyzed separately.As for BP NN, the effects of numbers of layers and nodes have been studied ; as for RBF NN, the influences of the number of nodes and the RBF‘s width have been studied. It is concluded that BP NN has converged much slowly in comparison with RBF NN. The conclusion that the RBF NN is suitable for modeling activated sludge system has been drawn. An automatically optimum design program for RBF NN has been developed, through which the RBF NN model of traditional activated sludge system has been established. 相似文献

Existence of interoperability within the enterprises is essential for textile supply chain to efficiently face the challenges from contemporary competitors,to find new business opportunities and to render better customer service.Exchange of business documents,being semantically consistent,is the way to achieve interoperability.However,heterogeneity of the structures of the enterprises poses challenges for establishing interoperability.Ontology based semantic interoperability framework has now been proven as an effective solution for enterprise interoperability.In this paper,the existing ontology-based interoperability solutions in the context of textile supply chain have been compiled and research gaps have been identified.The ontological methods,such as unified process for ontology（UPON） and methontology have been analyzed,and UPON have been shown as a suitable ontology development method for textile supply chain. 相似文献
