Research on model base system of GDSS based on SOA in heterogeneous environment

Aiming at the difficult problem that it´s hard to share models of group decision support system (GDSS) in heterogeneous environment, the paper constructs internal structure and applicable external scenario for model base system of GDSS using service-oriented architecture (SOA), which is an integration technology architecture. The authors design an access mode of model base system based on “service scenario” in order to improve the use efficiency of models and realize model services publication and call in distributed model base systems of GDSS in heterogeneous environment. As for development for GDSS, the paper may be used as a reference.
