基于MAS的移动服务链协同工作机制研究

基于多智能体系统（multi agent system，MAS）原理，对移动服务链的竞争和协同工作机制进行了模拟研究。首先，建立了门户，接入服务提供商、产品／服务商驱动和无线网络服务提供商之间的动态竞争和协同工作方式的优化模型；其次，基于进化算法，在Repast构架上，用java实现以上三种工作机制的多代理模拟系统；最后设计模拟实验场景，对三种工作机制下多期平均利润和风险等模拟结果进行对比分析，结果表明，协同工作方式较另外两种竞争机制，服务链总利润更高，设计合理的约束条件，能有效降低服务链利润风险。

Research on Collaborative Work Mechanism for Mobile Service Chain Based on MAS

The competition and collaborative work mechanism for mobile services chain were discussed based on MAS(Multi Agent System)theory.First of all,the dynamic competitive and collaborative work optimization model were modeled between e-commerce service provider initiated and products service provider initiated;based on the evolutionary algorithm,and used Java to implement multi-agent system of three kinds of work mechanisms above;finally,designed simulation scenarios,the expectations and variance(risk)of the max profits,and other simulation results for three kinds of mechanisms were compared and analyzed,the results show that the total profit for service chain of collaboration mechanism are higher than the other two competitive mechanisms,and the risk of service chain profits can effectively reduced by designing reasonable constraints.
