Overview of the Course
This course explores how experimental design, an important off-line improvement tool, can be applied to the product and process optimization phase of development. Specifically, techniques are presented that can be used to achieve products’ and processes’ optimal performance. This optimality is accomplished by using a strategy known as Response Surface Methods.
Participants will learn how to use their Design of Experiments knowledge to build models allowing the estimation of curvature and how to find a theoretical optimum based on this modeled curvature. They will also learn how to simultaneously optimize multiple responses. Desirability functions are employed to strike a balance between multiple responses through a suitable choice of input parameters.
Participants will have an opportunity to use his/her newly acquired knowledge to actually design, run and analyze a series of experiments via computer simulations.
This course does not teach participant on just how to point and click. The basic concepts underlying each tool are discussed before the use of the software is demonstrated.
Participants Managers and Engineers from all engineering disciplines including Process, Research and Development, Quality, Maintenance and Reliability.
