“Decision support system can function in many ways. They can organize information for decision situations, interact with decision makers, expand the decision makers horizons, present information for decision makers understanding and structured the decisions and use multiple-criteria decision-making models.”

Decision Support System

In this topic they discuss the different characteristics of Decision Support System (DSS). They have posses’ special characteristics that need to be considered and the End users of the DSS, by virtue of the type of problems they address and the learning they undergo.

Decision Support System (DSS) supports the decision-making process through presentation of information designed for the decision maker’s problem solving approach and application needs. It is also a way to organize intended information for use in decision-making that involves the use database. It helps to the decision-makers interact in a natural manner. Interacting with DSS will prove new and challenging for most decision makers and will provide new perspective on the decision-making process. DSS are designed to support decisions involving complex problems that are formulated as semi structured. It supports the decision process that leads to a solution and structured to support one-time decisions, it requires human judgment because human feels it is inappropriate to relinquish their judgment.

Decision Support Systems is also typically designed for either a particular decisions maker or a group of decision makers. The high degree of individualization allows the system designer to customize important system features to be able to adapt to the type of presentations. There’s a integrated hardware and software called a DSS Generator (DSSG) that a system analyst can use. They can lessen the time and cost associated in building a case-specific DSS. Hardware and software are the designate3d tools as “DSS tools”. DSS is best conceptualized as a process instead of a product. DSS change as the needs of the end-users change and the decision maker changes through interacting with the DSS process.
