MDA-based decision service composition system model and process mechanism of GBDSS

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.
