Why do you want to learn DOE?
Apply statistical knowledge, reasonably select test conditions, arrange tests, conduct a comprehensive and scientific analysis of data, establish a functional relationship between response and factors, or find out the overall optimal improvement scheme;
In product design, experimental design can effectively design and verify the performance of products with the lowest test cost and the shortest time;
In the manufacturing process, experimental design can be used to quickly find and optimize the process parameters that have a significant impact on the process output index from many influencing factors.
