  • Introduction to Multi-Agent Systems
  • The DIVAS Project
  • Architectural Design of DIVAS Framework
  • DIVAS Social World
  • DIVAS Environment Architecture
  • DIVAS Agent Architecture
  • Conclusion
multi agent systems mas
Multi-Agent Systems (MAS)
  • MAS is the New generation architectural design paradigm
  • Characteristics of MAS are
    • Decentralized system
    • No central control unit
    • Basic entities: agent and environment
    • Co-operative, collaborative processing
  • Standardization effort
    • Foundation for Intelligent Physical Agents (FIPA)
    • Object Management Group (OMG)
what is an agent
What is an “Agent”?
  • Agent
    • Is an autonomous software entity
    • has objectives to satisfy
    • possesses skills and can offer services
    • possesses resources of its own
    • can communicate, cooperate, coordinate and negotiate directly with other agents
    • acts in an environment that is partially perceived
the divas project
The DIVAS project

DIVAS (Dynamic Information Visualization of Agent Systems) is a framework used for the development, visualization and simulation of large scale distributed multi-agent systems.
