Architectural Design for Multi-Agent Simulation System Presented by: Ameya A. Velankar
Outline • 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) • 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.
