OR and AI approaches to decision support systems

First the concept of a decision support system (dss) is described. Then the first approach, in which the development of a network of models forms the kernel, is given. An example illustrates this approach. Then, architectures of decision support systems according to the first approach are given. Afterwards a second approach is considered, in which an (abstract) dss machine is described that can be tuned to specific decision situations. Finally the applicability of this approach is illustrated with an example.
