1. Value Engineering Lecture 11

2. Improving Details in Design  Most design involves modifications (improving details)  Modifications may include: Improving performance Reducing weight Lowering cost Enhancing appearance

3. Value Engineering Aim: To increase or maintain the value of a product to its purchaser whilst reducing its cost to its producer

4. Procedure 1.List the separate components of the product and identify the function served by each component. If possible, the actual product should be disassembled into its components; exploded diagrams and component-function charts are more useful than parts lists

5. Procedure (cont’d..) 2.Determine the values of the identified functions. These must be the values as perceived by customers. 3.Determine the costs of the components. These must be after fully finished and assembled.

6. Procedure (cont’d..) 4.Search for ways of reducing cost without reducing value or adding value without adding cost. A creative criticism is necessary, aimed at increasing value/cost ratio. 5.Evaluate alternatives and select improvements

7. Example 1 – Turbine Gears

8. Example 2 – Aircraft air valve

9. Example 3 - Pintle

10. Example 4 – Piston

11. Example 5 – Tabular heater

12. Tabular heater (cont’d..)

13. Example 6 – Electric motor

14. Example 7 - Torchlight
