Industrial Design of Experiments

STAT 321

Winona State University

Day one let s get started

Day One – Let’s get started!

Course Objectives

  • ·outline the basic steps of an industrial experiment;

  • ·design experiments using the concepts of randomization and blocking;

  • ·design and analyze two level factorial and fractional factorial designs;

  • ·contrast Taguchi's methods with classical methods;

  • ·recognize examples of poor statistical statements and graphics.

Design of experiments definition

Design of Experiments - Definition:

  • A scientific method for designing the collection of information about a phenomenon or process, and then analyzing the information to learn about relations of potentially important variables. Economy and efficiency of data collection have high priorities.

Advantages of doe

Advantages of DoE:

  • ·Process Optimization and Problem Solving with Least Resources for Most Information.

  • ·Allows Decision Making with Defined Risks.

  • ·Customer Requirements --> Process Specifications by Characterizing Relationships

  • ·Determine effects of variables, interactions, and a math model

  • ·DOE Is a Prevention Tool for Huge Leverage Early in Design

Industrial design of experiments

Steps to a Good Experiment

  • Define the objective of the experiment.

  • Choose the right people for the team.

  • Identify prior knowledge, then important factors and responses to be studied.

  • Determine the measurement system.

  • Design the matrix and data collection responsibilities for the experiment.

  • Conduct the experiment.

  • Analyze experiment results and draw conclusions.

  • Verify the findings.

  • Report and implement the results.

Current industrial usage
