Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous systems face challenges in dynamic and efficient coordination between agents, leading to suboptimal task allocation and response to real-world state variations, especially in large-scale deployments where perfect coordination may not be necessary.
Innovation Solution
A multi-agent mission planning system comprising a mission generator, tactical group planners, and a multi-agent planner that uses a Multi-Agent Language (MAL) to compute allocation vectors, allowing agents to perform missions while considering other agents in their tactical groups, and dynamically adapting between centralized and distributed management based on communication status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If exact coordination optimization is implemented for all agents, then task allocation quality is improved, but computational complexity becomes intractable
Solution Approach 1:
The patent segments the coordination problem by introducing a correlation order parameter k that limits optimization to small groups of agents rather than all agents globally. This segmentation transforms the intractable global optimization problem into manageable local optimization problems, where only agents within distance k of each other require detailed coordination, while distant agents use rougher approximation methods.
Solution Approach 2:
The patent applies partial action by implementing exact coordination optimization only for agent groups within correlation distance k, rather than for all agent pairs. This partial optimization approach achieves sufficient task allocation quality for locally critical coordination while avoiding the computational intractability of global exact optimization, balancing precision where needed with efficiency elsewhere.
2Loss of time
If strict real-time requirements are met with exact solutions, then response time is improved, but computational resources required increase
Solution Approach 1:
The patent segments the computational workload by correlation order k, requiring intensive exact optimization only for small local groups within distance k, while using efficient approximation algorithms for the remaining agent allocations. This segmentation enables meeting real-time response requirements with manageable computational resource consumption on embedded platforms.
Solution Approach 2:
The patent changes the parameter of optimization scope from global (all agents) to local (agents within correlation order k), and adjusts the solution precision parameter based on distance. This parameter change allows the system to meet real-time constraints by reducing the computational burden while maintaining sufficient accuracy for mission-critical allocations.
3Reliability
If perfect coordination between all agents is achieved, then system effectiveness is improved, but communication overhead increases
Solution Approach 1:
The patent segments communication requirements by introducing correlation order k, where agents only need detailed coordination information with other agents within distance k. Agents beyond this distance require only rough approximation coordination, dramatically reducing communication overhead while maintaining system effectiveness for locally-critical missions.
Solution Approach 2:
The patent applies local quality by providing high-quality detailed coordination information only where physically necessary (within correlation order k), and rougher approximation information elsewhere. This local differentiation of communication quality reduces overall communication overhead while maintaining reliability for missions where coordination is physically critical.
4Quantity of substance
If scalability is improved for large-scale deployment, then system size is improved, but coordination complexity increases
Solution Approach 1:
The patent segments the coordination problem by correlation order k, allowing the system to scale to large numbers of agents without proportionally increasing coordination complexity. Each agent only needs to coordinate in detail with a limited local neighborhood, making the coordination complexity per agent constant rather than growing with total system size.
Solution Approach 2:
The patent applies partial action by implementing detailed coordination optimization only for a fraction of agent pairs (those within correlation distance k), while using efficient approximation for the remainder. This enables scalable deployment of large agent swarms with manageable per-agent computational and communication loads.
