Dynamic view of decision domains for the design of active DSS

Active decision support systems must be able to operate in two different modes. The traditional mode consists of their performing tasks under the explicit control of the user. The active mode consists of their performing some reasoning of their own and taking initiatives. The active mode requires that they have a knowledge-base related to the domain of the decision. The author addresses the contents and the organization of the knowledge base. A generic architecture is proposed; it integrates the database and the model base of the DSS (decision support system). The advantages of this architecture in the context of active as well as traditional DSS are discussed
