Robust Control in Seamless Tubes Production

摘要

Deming (1975) defined analytic study as the one in which action will be taken in a cause-and-effect system to improve performance of a product or a process in the future. The aim of an analytic study is the prediction that one of severalalternatives will be superior to the others in the future. R. A. Fisher (1947) expounded principles for sound experimentation. Experimental design is an important tool to improve manufacturability of the product, to enhance result performance andreliability, to reduce cost and development time of the product.
