Before the lecture we will start with a story

Die Cast Engine Blocks

Experiments

All Engineers want improvement in their:

• Product• Process• Results

Q: What combination of variables will lead to the best result?

Design of Experiments

To get the best results you have to Choose the right variables for the

experiment Choose their values to test Choose what to measure and howGood Experiments don’t happen

They have to be carefully designed

Thus the subject:

Experimental Methods and Analysis

Course Objectives

1. To provide the Masters student with hands on experience on design of experiments as practiced in the industry.

2. To learn the application of statistical techniques and concepts to maximize the amount and quality of information resulting from experiments.

3. To have exposure to commercial statistical software used in the industry

Schedule - I

Schedule - II

How will you use this course at your work place?

Please think about it Think of an experiment Think of the inputs and outputs

This will become your mini project

Mini Project

Think of an experiment at your workplace

Think of the inputs and outputs

Design Of Experiments

Process

Uncontrollable Factors

Questions :

1. Which factors affect the response (output) ?

2. Which factor has the most affect on response ?

3. Which combination of factors have the most desirable effect ?

4. What should be the value of factors to get a certain value of response?

Measurable Output

Controllable Factors

Mini Project - II

Objective: The objective of this project is to …….

Methodology: What will you do? End Result: This is what you aim to

achieve
