...Information Systems researchers, academicians and technologists have built and investigated computerized Decision Support Systems (DSS) for approximately 40 years. This article chronicles and explores the developments related to building and deploying DSS. The journey begins with building model-driven DSS in the late 1960s, theory developments in the 1970s, and implementation of financial planning systems, spreadsheet-based DSS and Group DSS in the early and mid 1980s. Data warehouses, Executive Information Systems, OLAP and Business Intelligence evolved in the late 1980s and early 1990s. Finally, the chronicle ends with knowledge-driven DSS and the implementation of Web-based DSS beginning in the mid-1990s. The field of computerized decision support is expanding to use new technologies and to create new applications. In the 1960s, researchers began systematically studying the use of computerized quantitative models to assist in decision making and planning (Raymond, 1966; Turban, 1967; Urban, 1967, Holt and Huber, 1969). Ferguson and Jones (1969) reported the first experimental study using a computer aided decision system. They investigated a production scheduling application running on an IBM 7094. In retrospect, a major historical turning point was Michael S. Scott Morton's (1967) dissertation field research at Harvard University. Scott Morton’s study involved building, implementing and then testing an interactive, model-driven management decision system. Fellow Harvard Ph...

...CURRENT ISSUES OF DECISION SUPPORT SYSTEM Cynthia P. C. Lee Abstract This paper emphasized on the Decision Support System (DSS) defined in various ways depending upon the author’s point of view by Turban (1995), Little (1970), Moore and Chang (1980), Keen (1980), and Power (1997); history of DSS during late 1950s and early 1960s until millennium approached of Web-based analytical applications; the Decision support system (DSS) has been used in many different ways (Alter 1980, Power, 2002). Turban (1995) defines it as "an interactive, flexible, and adaptable computerbased information system, especially developed for supporting the solution of a nonstructured management problem for improved decision making. It utilizes data, provides an easy-to-use interface, and allows for the decision maker's own insights." For Little (1970), a DSS is a "model-based set of procedures for processing data and judgments to assist a manager in his decision-making." Moore and Chang (1980) define DSS as extendible systems capable of supporting ad hoc data analysis and decision modeling, oriented toward future planning, and used at irregular, unplanned intervals. importance of DSS to assist in high-level decision-making, assist academic advising staff, improve the quality and timeliness of marketing decisions, and medical diagnosis process; and current issues of DSS where decision-making as the most important activities for human beings, Clinical Decision Support Systems (CDSSs), several...

...and operating complex systems. Simulation is an cost effective means for exploring new ideas. It can be used as an effective communication tool which shows how an operation works while stimulating creative thinking for more improvements. One of the major advantage of simulation modeling is that we can begin with a simple model of a process and as we better understand the process we can gradually refine the model accordingly. this helps us to achieve good approximations for very complex problems within a short amount of time. Decision-making usually requires a lot of analysis of large amounts of data and complex relations. Decision support system are computerized tools designed and implemented for such purposes. A decision support system helps in an organization or business decision making activities. In an organization, the decision support system serves the management, the operations and planning levels of an organization. it helps people make decisions problems that can rapidly change and which cannot be specified easily in advance. There are many decision support systems. They can be classified into five types: * Communication driven decision support systems * Data-driven decision support systems * Document-driven decision support systems * Knowledge-driven decision support systems and * Model-driven decision support systems.
