Model based decision support systems

Abstract

More and more powerful tools are available to construct a DSS. Although the situation is improving for the professional domain user continuously, there is still a problem of one tool not providing all the functionality needed for the application in question. For example, the databases have extensive facilities for the handling of data but usually have limited modelling facilities. Subsequently it is important that the tools are of an ‘open design’ type so that they can be connected with each other as desired by the user.

As already stated it is usually possible to find suitable software to build the data base and the model. However, the evaluator is the heart of the DSS system in containing the real decision making part. Such a decision may be made by comparing two or more different scenarios run by the model. The requirements of the evaluator are usually application specific and need to be constructed by the domain expert.
