Concurrent Engineering

Definition

According to Pennell and Winner, 1989

Concurrent Engineering is a systematic approach

to the integrated, concurrent design of products

and their related processes, including,

manufacturing and support. This approach is

intended to cause the developers from the very

outset to consider all elements of the product life

cycle, from conception to disposal, including

cost, schedule, quality and user requirements.

Concurrent Engineering

Basics of CE

Basic Tenets of Concurrent Engineering

-Doing things simultaneously

-Focusing on the Process

-Converting hierarchical organizations into teams

Basics of CE

Basic Goals of Concurrent Engineering-Dramatic improvements in time to market and costs

-Improvements to product quality and performance

-Do more with less

Basics of CE

Management

-Good mgmt is vitally important

-Encourage communication

-Strong mgmt support

How it works?

3 Main Areas to Concurrent Engineering

1) People

2) Process

3) Technology

How it works?

Area 1: People

-Formation of teams

-Training

How it works?

Area 2: Process

-Changes in your processes

-Be open to change

How it works?

Area 3: Technology

-CAD/CAM

-Software. Hardware, and Networking

CE and MTIC

Better use of existing technology Innovate s the production process Innovates the product design Change the production method Change in functioning of the company Changes the relationship between

different dept.

Benefits of Concurrent Engineering

Low cost Team work Speed – to – market due to reduced

cycle time Quality design of producible item Quicker development period Customer satisfaction Low scrap and wastage

Benefits of Concurrent Engineering

Disadvantages

Concurrent design creates its own issues, such as :

The implementation of early design reviews,

The dependency on efficient communication between

engineers and teams, software compatibility, and

Opening up the design process. 

A concurrent design process usually requires that

computer models are exchanged efficiently, If such

issues are not addressed properly, concurrent design

may not work effectively.

Real world example

Titan Linkabit

-Develops circuit boards

- CAE technical manager, Chip Ciradot

Real world example

Titan Linkabit-Old CAD system: 21 weeks to develop 8-layer circuit board.

-Implemented new CAE tools and CE

-New circuit board: 12 weeks to develop, 10 layers, twice the functionality of the 8 layer.

Recapitulation

Concurrent Engineering: Simultaneous development of product and process.

Most important aspect is communication and formation of teams

Management support is vitally important

Don’t be afraid to change current processes and technologies
