Research on Grid-based and Problem-oriented Open Decision Support System

The characteristics of grid technology is suitable for constructing the platform of DSS, and can solve the problems of the development of DSS in distributed and dynamic decision-making environments. Open Grid Service Architecture (OGSA) is a new type grid architecture, which can support service creating, keeping and applying. With the inspiration of virtual enterprise building idea, this paper puts forward the architecture model of Grid-based and Problem-oriented Open Decision Support System (GPODSS) and discusses its operational process
