组合电子市场中多Agent联盟形成的动态特性分析

在给出一种多Agent中介系统控制的组合电子市场模型的基础上,利用基于群集智能的多Agent系统分析方法,针对中介主导的组合电子市场中大量消费者联盟形成的问题,从组合市场的宏观层次将其抽象为一个具有随机特性的群集系统,为多Agent间交互的动态特性作出宏观层次的定量分析.根据群集系统的速率方程,首先给出了一个反映组合市场中市场结构动态变化的微分方程,然后通过数值仿真,验证了组合贸易中多Agent联盟形成的可行性和有效性,分析了中介主导型商务系统这种新的电子市场模式存在的价值,并通过与相关工作的比较证明了多

Dynamics of Multiagents Coalition Formation in Combinatorial Electronic Marketplaces

A multiagents intermediary-driven combinatorial electronic market model is given. Applying multiagents coalition formation theory for it, a mathematical analysis methodology is used for customer coalition formation. At the macroscopic level of the marketplace, the combinatorial marketplace is described as a stochastic swarm system and the dynamics of multiagents coalition formation is studied. Based on the rate equation in swarm intelligence, a differential equation is derived, which gives the quantitative characteristic for coalition formation process of large-scale customers in the combinatorial market. Simulation experiments are performed to study the feasibility and validity of multiagents coalition formation in combinatorial trading. The global behavior of the system compared with correlative works proves the effective improvement of the dynamic process.
