The evolving role of decision support systems is evident from the text books which appeared since 1978 [1] [2] [4] [8] [9] [17] . However, it seems that the common interest in establishing user-friendly/ accepted systems has displaced the question how quantitative methods of operations research should be integrated into such systems. Moreover, while there is much empirical research on the management of information systems - see [3] [ 10] - we must state a lack of empirical research on decision support systems. Therefore this paper aims at - showing how OR methods are integrated into a DSS - reporting on the user behavior of such a system, and trying to find out some factors which are related to the efficiency of the system ...
