Supplier Integration
Introduction and motivation
Up to
80 %
of the development services are provided
by suppliers
The switch to the CAD system
CATIA V5
means a further
challenge
for integration of suppliers and data exchange
Cost
optimal exchange of development
data is needed
Implementation of
standards
to
meet
global
challenges
Goal of supplier integration is the reduction of complexity within data
exchange processes by increasing data emergence and data volume

Optimization
of handling
of large V5 data sets
Larger memory

Larger parts and assemblies
can
be loaded to CATIA
64 bit technology
Exchanged data sets
with suppliers
will continue to rise
64bit Architecture
necessary at
OEM and supplier
Migration of
data exchange systems
from UNIX to Windows
Exchange of CATIA V5
structure in
combination with configured EDM
Design-In-Context
as well as
IP-Protection
gets more and more
important
Introduction and motivation
Challenges data exchange
Details (2/4)
Wants to
work
independently
of OEM
systems
Automatic data exchange
without manual access to OEM
systems
Defined and
standardized
interfaces
Know-How protection
of
parametrical data
View of suppliers:
Ask suppliers to
work/archive in
EDM/CAD systems
of OEMs
Know-How of supplier in the
OEM-specific
Web Portals
is
expected
Residential Engineers
at
OEM side
View of OEMs:
Prognosis: Data exchange via Internet will replace the existing data

Data exchange with
different exchange
solutions
without
manual
interaction
Use of standards

ENX, ISDN, OFTP,
ENGDAT/ENGPART
Data exchange via
Portal
solutions
of OEMs
Reduced use of ENGDAT
(e.g. as "delivery note“ at
MMC)
USA
Europe
Asia
Today different local data exchange solutions exist – global standards
are needed
Challenges data exchange

Security in exchanged data …
Encryption of
ISDN

Line encryption for
ENX
Encryption of

IP-Protection
of parametrical
data
Introduction and motivation
Encrypted data exchange via
Internet over
OFTP V2
(encryption of connection/line)
End-To-End encryption
by use
of private/public keys with the
exchange partners
Use of
virus scanners
for
engineering data
Solutions for
IP-Protection
Today:
Tomorrow:
Security aspects and IP-Protection will be more and more important in a
global vehicle development process
