Establishment of Neural Network Mode for Ethylene Plant Based on the Genetic Algorithms

How to establish the neural network modes of ethylene plant based on genetic algorithms is introduced;first of all,the artificial neural network model structure has been designed according to the nonlinear degree between ethylene plant iostances and optimized any longer the network model parameters by use of Genetic Algorithms.This model is used to forecast the ethylene yield ratio and also to optimize the productive operation.An example showed that the process parameters of the ethylene plant can be speedily optimized by the genetic network model,and higher ethylene yield can be obtained.
