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.

Conclusion

Design Quality Attributes of DIVAS Architecture

  • Internal Attributes

    • Correctness and completeness

    • High cohesion and low coupling

  • External Attributes

    • Generality

    • Reusability

    • Plug-n-play
