Training aim

This interactive workshop introduces DOE to engineers, analyst and technicians. The focus is on the identification of the key process inputs that will give rise to the desired process output.

Learning objectives

Upon completion, participants will understand:

1. The need for good experiment design

2. How to select relevant factors (process inputs) for DOE

3. How to structure selection of tests to run, to minimise the amount of testing needed

4. How to design and run an experiment

5. How to graph and analyse DOE results

6. How to bring about a significant and sustainable process improvement, based on scientific understanding of influencing inputs.

Course outline

Structure: Two interactive workshops, run on consecutive days

Timing: 08:30  - 16:30 daily,     Maximum workshop size: 8 people

Day 1 of 2: Introduction to DOE, experiment design, selecting factors, centre points & blocking, running a simple full factorial experiment, graphing and analysing DOE results

Day 2 of 2: Fractional factorial experiments, Plackett-Burman designs, response surface methodology, evolutionary operations (EVOP), case study review of good & bad experiments
