... ofneural networks included ART networks, Hopfield networks, and SOM neural networks. Weaknesses ofneural networks for modeling and design of manufacturing systems result from neural networks ... representational models, artificial neural networks are particularly useful for modeling systems whoseunderlying properties are too complex, too obscure, too costly, or too time-consuming to be modeledanalytically ... used were multilayer feedforward networks, MAXNET,Hopfield networks, ART networks, and stochastic networks. The knowledge acquisition capabilities ofneural networks made them legitimate alternatives...
