Cooperation mechanism of multi-agent system driven by utility

Abstract

A cooperative mechanism amlong multiple agents was proposed. In the cooperative mechanism, a utility value was used to generate a preferred order for agents under different cooperative patterns. This utility value was achieved by computing the cooperative utility between one agent and the others under different tasks using a utility funct Accord-ing to this mechanism, agents can automatically choose the cooperative pattern, wh is the best to fit themselves to ac-complish their missions. Meanwhile, driven by utility, group task income can achieve the optimum, which enhances the cooperation efficiency of agent groups. A prototype system was designed at last to val te the proposed cooperative me-chanism. The effectiveness of this cooperative mechanism has been proved under the prototype system.
