Towards Adaptive Decision Support Systems: A Service-oriented Approach

Nowadays, managers in organizations usually have to confront increasingly complicated decision environments and dynamically changed decision demands. Traditional Decision Support Systems (DSSs) sometimes neglect that both requirements and objectives of decisions are indeterminate, and thus do not support flexible decision making. In order to meet dynamically changed contexts, DSS generators are introduced to build specific DSSs. However, DSS generators cost greatly but only bring about limited extensions. This paper reconstructs traditional DSS architecture using Service Oriented approaches. It describes the hierarchical model, conceptual model and implementation model for the framework of Service-based DSS, or SBDSS. In addition, it introduces the layered DSS adaptability model and presents the approach to high adaptabilities with context sharing and the assembly model of SCA and Spring Framework. Finally a prototype based on SBDSS is also given to show its feasibility.
