ENGINEERING TOOLS & METHODS
• Full Factorial Experiments −− Introduction to Cube Plots for 3- or 4-factor 2-level Experiments −− Experiment Set-Up −− Factor Levels, Repetitions, and “Right-Sizing” the Experiment −− Experiment Terms to Estimate (Main Effects and Interactions) −− High-Level Significance Evaluation • DOE Statistical Analysis
Participants will be given information on how to receive, install and configure a fully-functional 30-day trial version of Minitab for their use in class, and/or for their personal evaluation. While some computers will be available, attendees are encouraged to bring a laptop computer and/or a calculator to the seminar to provide additional hands-on time. Note: A similar course is availabe as a web seminar (ID# WB0932) and an on-demand course (ID# PD530932). Learning Objectives By attending this seminar, you will be able to: • Decide whether to run a DOE to solve a problem or optimize a system • Set-Up a Full Factorial DOE Test Matrix, in both Randomized and Blocked forms • Analyze and Interpret Full Factorial DOE Results using ANOVA, (when relevant) Regression, and Graphical methods • Set-Up a Fractional (Partial) Factorial DOE, using the Confounding Principle • Analyze and Interpret the results of a Fractional Factorial DOE • Recognize the main principles and benefits of Robust Design DOE • Decide when a Response Surface DOE should be run • Select the appropriate Response Surface Design (either Plackett-Burman, Box-Behnken, Central Composite, or D-Optimal) • Interpret Response Surface Outputs • Utilize the MiniTab TM Software tool to analyze data Who Should Attend This seminar will benefit engineers, designers and quality professionals in research, design, development, testing and manufacturing who are interested or active in one or more of the applications listed above. Individuals should have an engineering degree or equivalent coursework in math, statistics and computers. Topical Outline • Icebreaker: Team Problem Solving Exercise Using Engineering Judgment • What is DOE? −− Types of Designed Experiments −− Application Examples −− Where DOE Fits in with Other Tools/Methods • DOE Requirements: Before You Can Run an Experiment −− Writing Problem and Objective Statements −− Ensuring DOE is the Correct Tool −− Selecting Response Variable(s) and Experimental Factors
