基于群体智能的多机器人任务分配

针对具有松散和紧密耦合型任务的大规模多机器人系统,研究了基于群体智能的任务分配方法。系统采用层次结构,高层用蚁群算法实现松散耦合型任务分配的寻优,提出逆转分配思想让蚂蚁代表任务,为每个任务选择任务的承担者。底层分别提出了基于蚁群、粒子群蚁群和量子蚁群实现机器人联盟的形成——产生紧耦合型任务解,并进行仿真。仿真结果表明,基本蚁群算法得到的解质量最差;粒子群蚁群算法得到的分配解最好,但是运算时间最长;量子蚁群算法得到的解稍次于粒子群蚁群算法,但分配时间比另两种算法减少了一半。因此,在大规模的多机器人任务分配中,量子蚁群算法具有更强的适用性。

Multi-robot task allocation based on swarm intelligence

The task allocation was studied based on the swarm inteeligence for the large-scale multi-robot system with loose-and tight-coupled tasks adopting the hierarchial architecture. In the high level,the ant colony algorithm was employed to find the optimal allocation of the loose-coupled tasks,namely,based on the reverse distribution idea,taking each ant to form a task,an undertaker was chosen for every task. In the low level,the coalition formation algorithms based on the ant colony optimization(ACO) ,the part...
