Abstract: The problem of virtual enterprise coalition generation is converted into multi-agent problem in the paper.In view of the limitation of the only considering the cost and the optimal value of the union in solving the multiple agent problems in traditional way，this paper introduces allocation of resources and then puts forward the solution.Focusing on the method of virtual enterprise coalition generation which is based on improved ant colony algorithm and the task ability-sorting，the agents are divided in the process of solving according to the core abilities which the task needs，then this paper adopts improved ant colony algorithm to solve the problem，so that the agent meeting the mission requirements has the priority to be selected，that means the waste of advantage resources can be avoided and the allocation of resources is reasonable.The example through simulation analysis shows that the algorithm can solve multiple agent problems quickly and validly，showing the correctness of the algorithm.
