The development of an adaptive decision support system

An integrated conceptual model of an adaptive decision support system (ADSS) is proposed by following a unified research methodology. Adaptive behaviors of the DSS are identified based on previous research into adaptivity of information systems. A variety of knowledge that enables the system to adaptively behave is recognized. The concept of a reflexive system and a conceptual framework of decision-making organization are adopted to structure various components. This model consists of several components at two levels: the meta-level and the basic-level. The components in the basic-level unit communicate with the user and carry out the task of decision support. The meta-level is a controlling unit capable of introspecting the system's capabilities and limitations, and determining an appropriate action to adjust the capabilities of components in the basic-level unit.
