THE ROLE OF D.O.E. FOR ROBUST ENGINEERING: A COMMENTARY

摘要

The role of engineers is to create products/processes to perform certain functions; new products/processes never exist in nature. They can choose any system and set parameter levels of the system as they wish. These are called control factors. Such activities require cost and functionality predictions. When limited experiments are conducted in R&D laboratories it is impossible to predict exact output responses because laboratory conditions are quite different from downstream conditions arising, for example, from large scale manufacturing or customer requirements.
