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?

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