“…Also Hough and Duffy (1987) considered the MISs failed in trying to satisfy the information needs of executives. However, they saw that the MISs have succeeded as information systems of tactical and especially operative management because the decision making on those levels often is concerned with structured tasks (see also Alter, 1980;Sen and Biswas, 1985).…”

“…However, the ease of use of the DSSs was soon criticized by several authors (Rockart and DeLong, 1988;Sen and Biswas, 1985;Silver, 1991). Anyhow, the development of data communication techniques, micro computers and software has remarkably increased the use of the DSSs (Keen, 1987).…”

“…These capabilities, however, are rare. The users of DSSs are located on operative, tactical and sometimes even strategic managerial levels (Hough and Duffy, 1987;Rockart and DeLong, 1988;Sen and Biswas, 1985;Sprague, 1980).…”

“…This generalization effort was carried out both at the logical and implementation levels. At the logical level, the effort dealt with the question of how to create a generalizable DSS framework [1] and progressed through the 1980s [2,10,12]. At the implementation level, the effort concentrated on building systems that behave like a generalized DSS, such as GMIS, GPLAN [4], and others.…”

“…Lately, a new term "intelligent DSS" [6] (or expert DSS [10]) has been introduced that employs artificial intelligence (AI) techniques to extend the capabilities of knowledge system and problem processing system favored by Bonczek et al [2]. El-Najdawi and Stylianou [6] argue that an integration of the underlying tools is essential:…”

Computers and their associated programs have touched us all. Computer programs that are application oriented, require data, and produce information outputs (like reports, charts, recommendations, and others) are called "information systems."The three major kinds of information systems are transaction processing systems, management reporting systems, and decision support systems. Of these, the decision support system (DSS) is the most recent.The term was first introduced by Gorry and Scott Morton [7] approximately 25 years ago. According to them, a DSS is a system that supports managers in unstructured decision-making situations. This definition is very general, and does not explain the DSS structure. This is why we find it difficult to answer a simple question like "what is a DSS?" On the other hand, we can explicitly describe the other two information systems. For example, a transaction processing system is an application program whose main objective is to manage transaction data such as cash receipts, inventory data, orders, bills, invoices and so on. The management reporting system, on the other hand, stresses the importance of reports for the management.Why is the definition of a DSS so nebulous? Is there a fixed architecture for a DSS, or do DSSs favor varied architectures? Is DSS simply an user interface that acts as an umbrella to the underlying tools? Or is there a decision support process for which a DSS serves as an environment to manage this process? This paper attempts to clarify the DSS controversy by answering the above questions. Our discussion will reveal that in spite of a sustained interest in this area, research has been fragmented and dispersed over varied underlying domains like database management systems (DBMSs), artificial intelligence (AI), software engineering, graphical user interfaces (GUIs), and cognitive science.Rather than examining every definition of DSS since 1971, we will touch upon only those that we consider important. In their overview of the first DSS conference, Carlson and Scott Morton stateThe use of the term "decision support system" is relatively new and means different things to different people. For the purpose of this conference, it meant the flexible support of decision makers with computer-based information. In particular, we were interested in systems which provided useful support for problems with a lack of predefined structure. For all practical purposes, this type of computer support has not been available in the past [4].
