3. Motivation: a) System of Subsystems vs. SoS
System of Subsystems System of Systems
Conformance Autonomy Independence
Centralization Belonging Decentralization
Platform-centric Connectivity Network-centric
Homogeneous Diversity Heterogeneous
Foreseen Emergence Indeterminable

4. Motivation: b) SoS-definition
“Systems of systems are large-scale
integrated systems that are
heterogeneous and independently
operable on their own, but are networked
together for a common goal”
(Jamshidi, 2009)

5. Motivation: c) System Engineering vs. SoS Engineering
System Property System Engineering SoS Engineering
Unit of analysis Single System Integration of Systems
Target Optimisation Realistic Cost and Scheduling
Point of Confusion End Point Initial Deployment
Requirements Fixed Evolving
Boundaries Well-defined Indefinable

Approach
The generic method is proposed based on two Modelling methods:
• Modelling SoS based on its characteristics
(Baldwin and Sauser, 2009)
Generic SoS
modelling
method
• Modelling SoS by definition of interface
(Gutirrez-Garcia, 2009)

8. Generic Method for SoS-modelling:
Static Description:
• Individual Actions and Goals Si = { Sσi Sδi }
• Sσi = { Aσi Gσi }
Dynamic Description: Autonomy (i) = | Aσi | Diversity (i) = Aσi
• Action and Goals as a legal
constituent system
• Sδi = { Aδi Gδi }
Belonging (i) =
Connectivity:
Sσ1 Sσ2 Sσ3 Sσ4 Sσ5 Sσ6
Sσ1 0 1 0 0 0 0
Sσ2 1 0 1 0 1 0
SoS = { Si, … Sn, C, G }, n ∈ Z+>1, G ≠ ∅ Sσ3 1 1 0 0 1 0
Sσ4 0 1 1 0 0 0
Sσ5 0 0 1 1 0 0
Sσ6 1 1 0 0 1 0

9. Use case: Testbed - a production line

10. Use case: Testbed of a production line
Purpose: it is assumed that the method should work also for a traditional systems; a
testbed was considered as an example of a traditional manufacturing system.

12. Actions definition

13. Conclusions:
The generic method is capable to describe constituent systems of
SoS trough theirs characteristics and interfaces between them.
The ability of the method to describe goals and functionality of
the constituent systems can provide detailed yet simple
description of a heterogeneous, destributed systems of a large
scale.
The applications of the method to the use cases show the
aplicability to the domain of factory automation.
Further improvements and developments:
• Extension of the use cases evaluating the approach.
• A tool for SoS analysis and simulation should be developed.
