Design
(Cont.)
Functional analysis
– Customer specifications
– Product reliability
Design for X
– Manufacture or Assembly
Simplification, standardization, modularization
– Testing
– Repair
– Robustness to variations
Concurrent engineering
– Consider how product will be manufactured (process and
production planning) during design phase
Reduce cost and time to market
Product Design (Cont.)
• Computer-Aided Design
– Use of computer graphics to assist in the creation,
modification, and analysis of a design
– Common uses
•
•
•
•
Geometric modeling
Automated drafting and documentation
Engineering analysis
Design analysis
• CAD/CAM
– Generation of manufacturing instructions directly from

• Relationship to product lifecycle
– Typically production system lifecycle is longer than an
individual product’s lifecycle
– Production system will revert to earlier stages in its lifecycle
when new products are introduced
• Extent and cost depends on system flexibility
