Abstract: Profit allocation in enterprise coalition under fuzzy conditions is studied.The payoff function v and Shapley value are defined using the Choquet integral about fuzzy measures.The payoff function v thus defined is proved to have supperadditivity,and the Shapley value so defined proved to satisfy axioms such as efficiency,symmetry,dummy and additivity.The fuzzy Shapley value method for profit allocation in enterprise coalitions was thus given by examples.
