DOE and Regression Case Studies

Abstract

In this chapter, two additional case studies illustrate design of experiments (DOE) and regression being applied in real world manufacturing. The first study involved the application of screening methods for identifying the cause of a major quality problem and resolving that problem. The second derives from Allen et al. (2000) and relates to the application of a type of response surface method. In this second study, the design of an automotive part was tuned to greatly improve its mechanical performance characteristics.

Note that Chapter 13 contains a student project description illustrating standard response surface methods and what might realistically be achieved in the course of a university project. Also, Chapter 14 reviews an application of sequential response surface methods to improve the robustness and profitability of a manufacturing process.
