This study introduces methods for detecting conflicts in multi-agent systems (MAS) during plan integration. Techniques using intended goal structure (IGS) and E-PERT diagrams help agents resolve goal and plan conflicts efficiently.

Area of Science:

  • Artificial Intelligence
  • Multi-Agent Systems
  • Software Engineering

Background:

  • Plan integration in multi-agent systems (MAS) is complex.
  • Existing methods lack robust conflict detection.
  • Agents' intentions and actions need structured representation.

Purpose of the Study:

  • To develop and present techniques for conflict detection during plan integration in MAS.
  • To enhance the process of merging individual agent plans.
  • To improve the efficiency and reliability of multi-agent coordination.

Main Methods:

  • Representation of agent intentions using intended goal structure (IGS).
  • Extension of Project Estimation and Review Technique (PERT) diagrams into E-PERT diagrams for temporal relation tracking.

  • Classification of conflicts into goal, plan, and belief conflicts.
  • Utilizing pattern matching for detecting resource sharing and conditional conflicts.

    • Main Results:

    • A systematic approach to detect and eliminate goal conflicts before plan integration.
    • Successful merging of individual E-PERT diagrams to form integrated plans.
    • Identification of plan conflicts arising from resource contention or action precondition/postcondition mismatches.
    • Implementation and testing of conflict detection techniques in a testbed environment.

    Conclusions:

    • The proposed techniques effectively detect and resolve various conflicts in MAS plan integration.
    • E-PERT diagrams provide a traceable mechanism for temporal relations among agent actions.
    • The developed methods enhance coordination and reduce potential failures in multi-agent collaborations.
