Radial Basis Function Network versus Regression Model in Manufacturing Processes Prediction

Abstract

One of the objectives of manufacturing industry, is to increase the efficiency in their processes using different methodologies, such as statistical modeling, for production control and decision-making. However, the classical tools sometimes have difficulty to depict the manufacturing processes. This paper is a comparative study between a multiple regression model and a Radial Basis Function Neural Network in terms of the statistical metrics R2 and R2 adj applied in a permanent mold casting process and TIG welding process. Results showed that in both cases, the RBF network performed better than Regression model.
