英文摘要：

Aiming at characteristics of complex production process in process industries, an intelligent software system on optimal formula of production processing with multivariate factors based on pattern recognition, artificial neural network, genetic algorithm and nonlinear regression methods was introduced. Design philosophy, architecture, key technologies and implementation methods of the proposed system were narrated. The proposed system was designed to solve problems on multi-factor , high noise, nonlinear, non-Gaussian distribution and non-uniform distribution in optimal industrial complicated craft process. The architecture of the system was designed by using agent technology, and the domain model was constructed by the least square method and Chebyshev polynomial. Then the optimal solution of model was solved by the evolution algorithm, and learning sample data was gained by the orthogonal test, Applications indicated that these methods could provide guidelines for the industrial production with allowable error even though a few experiments were made.
