2. Basic Concepts for Supply Chain
Management of Supply Networks
 Supply Networks follow by nature Distributed Business
Processes
 A state of the art System Architecture allows now to follow
the requirements of the Distributed Business Architecture
 Collaboration Levels allow the members of a Supply
Network to run their own strategy as well as to cooperate
in optimizing the Supply Network
 Supply Networks are dynamic control networks and incline
in specific cases respective configurations to oscillate
 Supply Networks are treated as a superposition of Supply
Chains

4. Basic Concepts for Modeling of Supply
Networks
The goal is to reduce the complexity of supply
networks from a n:m relationship to a simple 1:1
one
Because the simple 1:1 relationship is well
understood and in many cases implemented
recursion leverages of this fact
The Recursive Model of a Supply Network allows
different views to the network and helps to take
advantage of the solutions already implemented
and proofed in reality

12. Traditional Architecture:
Centralized Systems
Basic Information Flow with centralized SC Process Model Server
Back-end systems in every organization keep dynamic data and static data (e.g. parameters) needed
in the SC Process Model
These back-end systems need to update the central SC Process Model Server after every status
change (e.g. “inventory level for partnumber A01 drops to 100 units”)

Basic Information Flow in SC Process Model Interoperability Scenario
 Back-end systems in every organization keep dynamic data and static data of SC Process Recursive Model
 These back-end systems need to update the SC Process Model instances after every status change
(e.g. “inventory level for partnumber drops to 100 units”)
 SC Process Model Instances need to synchronize adjacent SC Process Model Instances
