摘要:

在时间敏感的动态任务中,多无人机团队必须对新信息和新目标快速响应。本文提出一种动态去中心化任务分配算法,用于分配在任务分配问题求解过程中在线出现的新任务。该算法扩展了去中心化任务分配算法 Consensus-Based Bundle Algorithm(CBBA,基于共识的捆绑算法),无需对现有任务进行完全重分配即可快速分配新任务。CBBA with Partial Replanning(CBBA-PR,带部分重规划的CBBA)通过在每轮任务竞价中重置各智能体先前分配的一部分任务,使团队能够在收敛时间与增强协调之间进行权衡。通过重置每个智能体最后分配的任务,我们能够确保团队收敛到无冲突解。CBBA-PR还可通过减少参与重规划的团队规模得到进一步改进,从而进一步降低团队的通信负担和CBBA-PR的运行时间。最后,我们在多无人机仿真中验证了CBBA-PR更快的收敛速度和提升的解质量。

英文摘要:

In time-sensitive and dynamic missions, multi-UAV teams must respond quickly to new information and objectives. This paper presents a dynamic decentralized task allocation algorithm for allocating new tasks that appear online during the solving of the task allocation problem. Our algorithm extends the Consensus-Based Bundle Algorithm (CBBA), a decentralized task allocation algorithm, allowing for the fast allocation of new tasks without a full reallocation of existing tasks. CBBA with Partial Replanning (CBBA-PR) enables the team to trade-off between convergence time and increased coordination by resetting a portion of their previous allocation at every round of bidding on tasks. By resetting the last tasks allocated by each agent, we are able to ensure the convergence of the team to a conflict-free solution. CBBA-PR can be further improved by reducing the team size involved in the replanning, further reducing the communication burden of the team and runtime of CBBA-PR. Finally, we validate the faster convergence and improved solution quality of CBBA-PR in multi-UAV simulations.
