Module Summary

This seminar with hands-on application workshop prepares attendees for immediate applications of the Taguchi experimental design technique for product and process improvement.

DAY 1

Overview- Taguchi approach

New disciplines

Definition of Quality

Loss Function

Attractiveness of Taguchi Approach

Review basic concepts in experimental design

- Types of factors and levels

- Common experiment designs

- Orthogonal array vs. one-factor-at-a-time experiments

Practice Problem

Project objective Evaluation Criteria

Need for combining multiple evaluation criteria into a single index

Experiments designed using orthogonal arrays

- Experiments with all factors at one level

- Experiments mixed level factors

Practice Problem

Experiments to study interaction

- Trade off between factors and interactions

- Test for presence of interactions

- Test for relative influence of interaction

Basic analysis and strategy for experimentation

Practice Problem

DAY 2

Experiments with mixed level factors

- Upgrading 2-level columns into a 4-level array

- Downgrading (dummy treatment) columns

- 15 different experiments using an L-8 array

Practice Problem Combination Design (special design tool)

Strategy for Robust Designs

- New attitude toward uncontrollable factors

- Outer array for robust design

DAY 3

Analysis of Results

- Main effect study for influence of factors

- ANOVA for relative influence of factors

- Performance at optimum condition

- Confidence level and interval (C.I.)

- Transformation of S/N data

Practice Problem

Brainstorming for experimental design

- TEAM: the new disciplines in workplace

- Order of discussions in planning session

- Participants and facilitation of planning

Computation of cost/ LOSS FUNCTION

Reference and Application assistance

- Project application guidelines

Design and analysis using computer

software

Group reviews and exercise

Computer Software (Qualitek-4)

Class project & presentation by the groups

Who Should Attend

Product/Process Design Engineer, R&D Scientists, or QA Personnel, Manufacturing. Manager, Director or Senior Engineer (who wish to lead, teach, and introduce this technique within your organization)

Deliverables

This seminar with application workshop will prepare you for immediate applications of the Taguchi approach for designing robust products and processes. The goal is to make you ready to apply the technique in your performance improvement and variation reduction projects. You will know how to plan, and lay out experiments.

Prerequisites
