Abstract：Agent coalition is an important cooperative manner in multi-agent system. Its performance counts for much in task accomplishment. However, the existing methods have a lack of performance evaluation on agent coalition after coalition formation. In this paper, D-S evidence theory is adopted to make uncertain and incomplete evaluation on agent coalition according to agent ability, harmonious performance, communication cost, familiarity and continuable expansibility. A two-layered evaluation method on agent coalition is proposed, and its evaluation accords with process of human thinking and judgement. The agility, validity and rationality of the method have been illustrated by the example.
