Design of Experiments (DOE) for Engineers
I.D. # WB0932 Duration 12 Hours
Design of Experiments (DOE) is a methodology that can be effective for general problem-solving, as well as for improving or optimizing product design and manufacturing processes. Specific applications of DOE include, but are not limited to, identifying root causes to quality or production problems, identifying optimized design and process settings, achieving robust designs, and generating predictive math models that describe physical system behavior. This competency-based web seminar utilizes a blend of reading, discussion and hands-on to help you learn the requirements and pre-work necessary prior to DOE execution, how to select the appropriate designed experiment to run, DOE execution, and analysis of DOE results. You will experience setting up, running, and analyzing simple-to-intermediate complexity Full Factorial and Partial Factorial experiments both by hand and using computer software. You will also set-up and analyze Robust/Taguchi and Response Surface experiments utilizing computer software.

Each participant will receive a 30 day MinitabTM product trial copy for use in the web seminar. Due to the nature of the online format, each participant will be expected to dedicate approximately one hour to complete "homework" and/or short reading assignments in preparation for each session.

Note: A similar course is available as a classroom seminar.

Learning Objectives
By participating in this web seminar, you will be able to:
  • Determine when DOE is the correct tool to solve a given problem or issue
  • Select the appropriate DOE experiment type (DOE Goal) for a given application
  • Set up simple Full Factorial DOEs by hand, using cube plots
  • Set up and analyze any Full Factorial DOE using Minitab
  • Identify appropriate partial factorial design(s) based on one's application
  • Set-up and analyze Partial Factorial DOEs, simple Robust Design (Taguchi) DOEs, and simple Response Surface DOEs using Minitab
  • Recognize the structured process steps recommended when executing a DOE project
Who Should Attend
This web seminar will benefit engineers involved in product design and/or optimization; process design and/or optimization; quality improvement efforts such as defect elimination, warranty avoidance or similar initiatives; and technicians, analysts and managers who support engineers in these efforts. This course has no specific course prerequisites. However, participants are expected to have some math background, that includes elementary statistics. Since the course includes demonstration and hands-on use of Minitab, participants should have some familiarity with Windows-based personal computer applications.
