Combining RSM and Taguchi Methods to Improve Process/Product Quality

Both Response Surface Methodology (RSM) and Taguchi Methods have their advantages and disadvantages when they are used to optimize parameters of products/processes. Based on the analysis and comparison of these two methods,the paper presents a double response surface method to combine RSM and Taguchi Methods in order to make use of the advantages of RSM and Taguchi Methods. The proposed method can be used in DOE of robust design to improve the quality of products/processes.
