A computer system specifically designed to assist managers in making unstructured or semistructured decisions, i.e. the nature of the problem requiring a decision is not known in advance. A language subsystem has to be included in the DSS to allow users to communicate easily with the system and a problem processing subsystem, such as a spreadsheet, is also required. Typically, a system of this type has a store of internal data and is able to access external data. A group decision support system (GDSS) is designed to facilitate group decision making. See also data warehousing; expert system; management information system.
