CONCURRENT ENGINEERING (CE)

Methodology of CE

• Reduction in number of design changes

• Cost of changes in design

• Holistic approach to product development

• Robust product

• Reduction in lead time for product development

Strategy for CE

• Integration of product and process development, and logistic supportand logistic support

• Closer attention to the need of customer

• Adoption of new technology

• Continuous review of design and development process

R id d t ti i f ti h• Rapid and automation information exchange

• Cross functional team

• Rapid prototyping

TECHNIQUES TO IMPROVE MANUFACTUREABILITY AND TO REDUCE LEAD TIME

11

Design for X

• Design with less number of parts and assy

P d t i ti t t h t d• Product variation to match customer need

• Fasteners for ease of assembly

• Ease of fabrication/manufacture

• Proper tolerance

• StandardizationStandardization

• Minimum setup

• Minimum changes of design

13

Improving the design

• Value Stream Mapping (VSM)

• Failure Mode and Effect Analysis (FMEA)

• Failure Mode, Effect, and Critically Analysis

Taguchi Method for Robust Design

• Assume that product quality and robustness f ti f tare functions of parameters.

• Use statistical analysis to rank the importance and contribution of each parameter, usually in descending order

• Reduce the number of researchReduce the number of research

Value engineering

• Value is a ratio performace to cost

• Maximize the value of product

• Types of value: ability and desireability

Product Life‐cycle Management (PLM)

• Engineered to order

• Issues:

– Cost efficiency

– Product quality

– DFMA

– Time to market– Time to market

– Serviceability

Components of PLM Software

• Engineering design

• Knowledge management and process automation

• Product visualization

• Realtime collaboration

• Managing life‐cycle project

• Assessing and capturing customer requirement

Components of PLM software

• Supply chain management
