服务联盟与协同演化策略研究

Research on the strategy of service federation and cooperating evolvement

文章提出了一种新的服务联盟与协同演化策略,在新的联盟对策中效益产生分为联盟扩张效益与对外提供服务效益两种,用联盟收益率与服务收益率来评价联盟与服务的活力指标,并提出了按贡献大小划分的效益分配原则。新的协同策略通过联盟交互的信任理论关系来完成。经过理论分析与实验结果表明,提出的联盟与协同对策改善了利益分配的合理性,增加了对服务实体协同工作演化过程贡献的表达,具有较强的联盟内聚力与有序进化能力,对构建有序演化的协同科学计算环境具有较好的指导意义。

A new strategy of service federation and cooperating evolvement is proposed in this paper. The strategy involves two kinds of benefits （federation-expanding benefit and service-providing benefit）, using the benefit rate of federation and service to evaluate the activity index. Also we＇ve come up with the principle that divides the benefit by the rate of contributing. The new cooperating strategy bases on the trust relationship of the federation communication. According to the theoretical analysis and the experimental result, the idea of involving the concept of federation and cooperating strategy not only keeps the benefit division in a reasonable way, hut also enhances the expression of contribution to the cooperating evolvement of service entities. The strategy is capable of keeping the cohesion inside the federation and orderly evolving, which is meaningful for constructing the cooperating scientific computing environment of orderly evolvement.
