In a historical/developmental sense, decision support systems (DSS) came before artificial intelligence systems. Some might say that artificial intelligence systems haven’t really come yet. A clinical decision support system is a DSS used in a medical environmental; however, artificial intelligence could be used for “clinical decision support”. I don’t see the two as mutually exclusive, but rather complimentary techniques.
1. DSS tends to be aimed at the less well structured, underspecified problem that upper level managers typically face;
2. DSS attempts to combine the use of models or analytic techniques with traditional data access and retrieval functions;
3. DSS specifically focuses on features which make them easy to use by noncomputer people in an interactive mode; and
4. DSS emphasizes flexibility and adaptability to accommodate changes in the environment and the decision making approach of the user.
