Supply chain is a complicated, open system, for the constant development, and fierce degree of market competition of the society increase day by day, the discrimination and management of risk of Supply chain are more essential. Kinds of risk factors of Supply chain are analyzed in the text, according to the influence degree of each risk factor, a method combined BP neural network and fuzzy evaluation...
A new algorithm of pattern recognition based on RBF neural network and monkey-king genetic algorithm (MK-RBFNN) is prsented. The algorithm includes two parts. The first parts is that Monkey-King genetic algorithm is introduced to determine the initial positions and number of the hidden layer centers in RBF network. The second part is to set up the RBF neural network to do pattern recognition by learning...
Some clients are in arrears with a great amount of electricity charges in operation of power system, which has seriously hindered the healthy development of electric industry. Evaluation of clients?? credit is an important problem of management in power supply enterprises.Considering the training time and the accuracy, a new algorithm based on Support Vector Machine (SVM) and VIKOR method is adopted...
Automatic acquisition of ISA relations is a basic problem in knowledge acquisition from text. We present a method that acquires and verifies ISA relations from large Chinese free text. It initially discovers a set of sentences using Chinese lexicosyntactic patterns. Then we combine outside layer removal and inside layer gathering for acquiring concepts of constituting ISA relation. Finally, ISA relations...
