As the popularity and use of the World Wide Web (the Web) increases daily, many technologies and applications that were initially developed and used as stand alone tools are migrating towards the Web. Decision support technologies are examples of applications that traditionally have been developed as stand alone systems. One feature common to all decision support systems is that they require user input to produce results. However, due to some inherent limitations with the Web, some modifications must be made to allow users to interact with these technologies. Common Gateway Interface (CGI) programs, or scripts, provide Web servers the capability to produce dynamic documents and maintain user information or state. With CGl scripts, developers can capture user entered data access external applications to process the data, and return the results. Using CGI scripts to interface with database applications gives Web servers the ability to maintain state by tracking user data, information, and preferences. This thesis implements a Windows spreadsheet based decision support system (DSS) designed to optimize radar coverage of tactical aircraft. Using Delphi to write CGI scripts, the Web based DSS allows the user to enter data to run a new problem, save input and output data, and retrieve the saved data at a later time.
