Abstract: To apply the multi-agent system task allocation algorithm to dynamic environment, an improved contract net protocol was proposed. First, the agent capability model and the tasks description of agent execution were studied. Secondly, the agent changed its capability dynamically by putting the executing tasks out to tender, so that the tasks could be redistributed. Finally, the feasibility and effectiveness of the proposed method were proposed by building a simulation system of AGV warehouse. The results of simulation indicated that the proposed method could reduce the total time for fulfilling the tasks effectively, improve the overall efficiency of the system and improve the capability of multi-agent system to adapt to dynamic environment.

Key words: capability model, improved contract net protocol, dynamic environment, multi-agent system, task allocation
