Industrie 4.0 / Industrial Internet
Industrial Internet is the next generation of the Internet. It is a global system based
from networked computers, sensors, actuators, machinery and equipment. Merging
the physical world with the virtual world of the Internet and the software allows to
develop and apply Internet-based business models and new services..

The term industry 4.0 was coined in Germany and is initially very strong production oriented. In English-speaking countries, the
term Industrial Internet is common. It supplements the terms Internet of Things (IoT) and Internet of Services (IoS)

Engineering
Physical Assembly, Document &
Bill of Materials (BoM) Centric Approach to drive
the Supply Chain
Integrated Electronic, Mechanical,

Modern systems and products now more software intensive, more
complex delivery & management
Relationship between engineering & software orgs is often loosely
connected
Current solutions typically require all lifecycle data to be physically
located in PLM/PDM tools
Requires data to be replicated across multiple tools or data stores,
complex to manage

Source IBM
Data is stored and maintained by the tool that is best suited for
those data
Other tools to gain access via linked data methods built on open
standards for data sharing, not proprietary interfaces and
databases
Provides an open environment where engineers have access to
all relevant information needed, regardless of source

Some Thoughts: We need Standardization but…….
Persistent Administration in an extended PLM and/or ALM System for the following MBSE artefacts:
− Requirements, Functions, Behavior and Logical Elements two levels hierarchy and network
Version/revision control, ECM and Configuration Management needed for traceability (product
reliability, ISO 9001, ISO 262606,….)
Seamless Integration into existent Enterprise ALM/PLM solution
One single source of truth
Integration of MBSE in the enterprise ECM (Engineering Change Management) and CM (Configuration
Mgmt)
Version and Revision Management as basis for CM
Integration of the MBSE Authoring Systems via TDM into PLM and ALM
4 Level VDA concept
Security, Safety and common access rights
Visualization of the MBSE artifacts
Data Exchange in the early phase based on Standards (OSLC is not designed as a data exchange
standard)
Eventual co-existence between OSLC (integration) and PLCS (data exchange)
