Abstract:Payoff distribution of overlapping coalitions is a difficult topic in multi-agent systems. A payoff distribution strategy of overlapping coalitions for concurrent multiple tasks is proposed in this paper. Based on the idea of more abilities for more works, multiple concurrent tasks are dispatched in parallel by proportional allocation. Meanwhile, the payoff of overlapping coalitions is distributed according to the results of task dispatch. Then, a sufficient and necessary condition that one agent satisfies the principle of non-reducing utility when joining multiple coalitions is deduced. Finally, the effectiveness of the proposed method is proved by an example, and a comparative analysis between the proposed strategy and the serial utility allocation is carried out. The result shows that when a new agent applies for joining coalitions, the proposed strategy can satisfy the condition of non-reducing utility more easily and it has better timeliness.
