Agent coalition is an important cooperative manner for applications where an agent can't efficiently finish a task by itself and coalition performance counts for much to the accomplishment of tasks. Existing researches in agent coalition problem lack for sound evaluation of coalition after coalition formation. The hard topic is how to evaluate a coalition from multi-point of view and to aggregate all experts' opinion. In this paper, D-S evidential theory is adopted to make an uncertain and incomplete evaluation of agent coalition according to ability, cooperation, communication spending, familiarity and sustainable development. And a two-layered evaluation method of agent coalition is proposed. Finally, a typical example is displayed to analyze the process of evaluation.
