Decision Support Systems are created to help people make decisions by providing access to information and analysis tools. many stockbrokers now use programs that will automatically put in requests to sell shares once they reach a certain price (either high or low). A DSS creates a mathematical model of the system which helps decison making about actions affecting a person organisation. Another example of a decision support system is the simple analysis tools that banks use to help formulate loans for prospective customers. A DSS allows the users to pose what-if questions and by changing a number of variables and then find out what the outcomes would be. In the home loan DSS customers can analyse how paying off more each pay would affect their loans, how a different type of loan may make it easier to make ends meet and by so doing tailor the loan to suit the customer.
A DSS depends upon the accuracy of the maths involved in creating the model and the ability of the user to accurately interpret the resulting data.
Example
Computer-driven trade has significantly affected the stock exchange. The Australian stock exchange uses a system called SEATS (Stock Exchange Automated Trading System). Computer and telecommunications technology, besides opening a wide market in over the counter dealings, has also given rise to trading on an international level. Personal computers and modems allow trading to occur around the clock, and the securities trading on one major stock exchange can now significantly affect the trading on others.
