摘　　要：基于网格的决策支持系统(Grid based decision support system,GBDSS)的决策服务组合建模既要考虑领域内特定决策问题的过程建模,又要考虑所采用的方法的可行性和效率.提出了基于模型驱动架构(Model driven architecture,MDA)的GBDSS决策服务组合技术架构及其平台层次模型,论述了模型中各模块的运作机理,分析了其建模协议簇的层次结构.该模型通过平台无关模型(Platform independent model,PIM)到平台具体模型(Platform specific model,PSM)的转换实现GBDSS决策服务组合过程中抽象决策过程建模与实际组合决策服务执行之间的分离及动态映射,增强了GBDSS决策服务组合的自动化程度,提高了GBDSS解决复杂问题的能力.The modeling of GBDSS decision service composition should consider not only the modeling of decision-making processing in specific domain but also the feasibility and efficiency of modeling approach. An architecture of MDA-based GBDSS decision service composition was proposed. Then the hierarchical system structure, process mechanism, and modeling protocols of this architecture were discussed in detail. The model tends to separate specific decision service from abstract decision-making processing by translating PIM to PSM. It advances the automation of GBDSS decision service composition, and enhances the ability of GBDSS complex problem-solving.
