Problem faced by command general at Persian gulf war

• The Second Marine Aircraft wing had to plan its activities in a fast-changing political and military environment.

• The commanding general and his staff of about 110 needed large amounts of information, such as personnel availability, logistics status, and weather conditions and forecasts.

• Getting all this information via telephones and paper reports was a slow and possibly inaccurate task.

• Using RediMaster (from American Information Systems), a local area network, and information downloaded from a mainframe or PCs, and EIS was constructed that could provide the commanders with the needed information in seconds.

• The EIS included e-mail, a calendar, word processing, a spreadsheet, graphics software, and anything else that could be used to support commanders.

• supports business or organizational decision

making activities.

• DSSs serve the management, operations, and

planning levels of an organization (usually mid

decisions, which may be rapidly changing.

• Decision support systems can be either fully

computerized, human or a combination of

both.

While academics have perceived DSS as a tool

to support decision making process, DSS used

as a tool to facilitate organizational processes.
