What is Fielded Object Network (FON)?
  • Object Network extension aiming at a multiresolutional and massively parallel representation and implementation tool
    • [4] Gudwin, R. R., Gomide, F., An Approach to Computational Semiotics. Proceedings of the ISAS'97 - Intelligent Systems and Semiotics: A Learning Perspective -Gaithersburg, MD, USA - 22-25 September, 1997
  • Object definition: object is an individual and atomic entity
  • Definition: FON is an object system where the objects are composed by five elements:
    • attributes (attributes  parts)
    • functions ( method)
    • field
    • connections
    • life cycle.

FON object: Field
  • Field
    • place where the object places the objects that it contains
    • Physical parameters
      • spatial structure and dimension.
    • Physical laws
      • rules that affect a subset of attributes of the contained objects
    • Embedded nature
    • Universe object
    • Atomic object

Field

FON object: Life cycle
  • An independent and parallel dynamic system that is ruled by some kind of algorithm while the object exists
  • A processing stream related to an object
  • Life Cycle x Embedded Nature
  • Passive x Active

Field

FON object: Connections
  • Field concept  data visibility restrictions  visibility scope
  • Normal visibility scope (direct access)
  • Connection: communication line between two or more objects
  • Two kinds of communication (interaction): physical & logical

fon objects connections and assimilation
FON objects: connections and assimilation
  • Physical communication
    • embedded nature + hit function
  • Logical communication
    • connection + assimilation function
    • an object must explicitly allow its assimilation before being assimilated

FON objects: assimilation types
  • Three different assimilation types:
    • Destructive assimilation
    • Non-destructive assimilation

why and when fon
Why and when FON?
  • Distributed Artificial Intelligence (DAI)
    • Distributed Problem Solving (DPS)
    • Multi-agent Systems (MAS)
  • FON = Framework for DAI
  • Highlights:
    • Using CORBA or PVM: FON can be distributed in a network
    • FON objects  mobile objects
what is the relationship between fon and semiotics
What is the relationship between FON and semiotics?
  • Semiotic Oriented Autonomous Intelligent Systems Engineering
    • Analysis
      • Semiotic analysis + UML extension
    • Project
      • FON modeling + UML extension
    • Design
      • FON framework
conclusions
Conclusions
  • Fielded Object Network (FON) is an extension of Object Network (ON)
    • Object
    • Life Cycle
    • Field, embedded nature
    • Communication:
      • physical
        • hit
      • logical
        • Destructive assimilation
        • Non destructive assimilation
        • Message passing assimilation
  • FON is a framework for DAI
  • Example: GSM implementation using FON
  • Application example: AGV
  • FON can be used in a “Semiotic Oriented Autonomous Intelligent Systems Engineering” as modeling and implementation tool
