  • W.C. Baldwin and B. Sauser, “Modeling the characteristics of systemof system,”J.O. Gutirrez-Garcia, F.F. Ramos-Corchado, and J.-L. Koning, “Obligations as constrainers, descriptors, and linkers of open system of systems,”
  • The transformation is discussed in Wells & Sage, 2009.(Einstein portrait by Bernard Pras from recycling trash)
  • Thus,SoS engineering has shifted from classical phylosofy and approaches of system engineering, and new challenges, which SoS-concept is posing to Engineering, appeal to development of new methods which would allow to model, describe and simulate SoS specific nature.
  • Despite on hudge interest to the subject expressed in academia and industry, a small number of computational methods has been yet presented.Hypothesis: Integration of Definition of Characteristics for description of properties for each component and Definition of Interface for communication between components could provide a completed and relatively easy description of the whole production system with all related processes
  • In [7], there was introduced a method to model SoS by defining descriptive interfaces between constituent systems that contain the obligations that should be complied. A SoS is depicted as a multi-agent system, and each agent is capable of releasing a certain number of obligations. These obligations are accomplished either by actions taken by the agent itself, or by commanding other agent(s) to complete some certain actions.
  • The method is capable to describe the production process based on actions and goals and the description evolves with the increasing of the component systems’ number. Thus the modelling method can be utilized to more complex systems.

    4. 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)

    6. 6. Background: Computational methods for SoS modelling Traditional SoS-specific (Clark, 2009) Domain Definition by Definition by Building Taxonomy Characteristics Interface V-Model Blocks (Bawlding & Sauser, (Gutirrez-Garcia et (DeLaurentis, 2008) 2009) al., 2009) Clear representation;  Expresses  Agent-based approach and a language Easy for paractical execution; operational description. independence; Ignores essential characteristics of  Hypothesis:SoS like communication and  Furthercooperation; development for Def. of Characteristics + Def. of Interface System is more then subsystem better readability =congregation. Description of the Production System
    7. 7. 7 ApproachThe 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. 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 0SoS = { 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. 9. Use case: Testbed - a production line
    10. 10. Use case: Testbed of a production linePurpose: 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.
    11. 11. Actions definition
    12. 12. 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.
