基于改进合同网的多Agent系统协作机理研究

针对传统合同网协作模型的不足和舰船动力辅助系统的特点,从三个方面对合同网加以改进,给出了一种适合于舰船动力辅助系统多Agent控制系统的改进合同网模型,该模型不但能够提高协作效率,而且能够有效的解决被控系统在突发事件和故障状态下的交互协作问题.以简化的冷却水系统为例,以JADE为开发平台,将该模型应用于其多Agent控制系统开发中,通过仿真模拟了Agent之间的协作过程,并将协作结果与理论结果比较验证了其正确性,为深入研究多Agent系统的协作机理提供了通用的方法.

Research on Cooperation Mechanism of Multi-agent System Based on Improved Contract Net

In consideration of the shortcomings of the traditional contract net cooperation model and the characteristics of auxiliary system of marine power plant,three improved schemes of contract net are concluded.On this basis,an improved contract net model is proposed which is suitable for multi-agent control system of auxiliary system of marine power plant.The model can not only enhance the cooperation efficiency but also solve the cooperation problem under abnormal conditions efficiently.Lastly,take the simplified cooling water system as an example,by using JADE as the development platform,the improved contract net is applied to the development of the multi-agent control system.The cooperation process is simulated and the cooperation results are validated by comparing with the theoretic results.The simulation affords a universal method for studying the cooperation mechanism deeply.
