Concurrent Engineering
By:-Abdullah HashmiLata TiwariPragya DograShariq Anwar
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
Process of CEconcept
Testability
Manufacturabilty
Design Verify Review Produce Test
Service
Cost reduction
Quality improvement
Process of Concurrent Engineering
Linear product development vs. Concurrent Engineering
Time saving by CE
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
