Decision Support Systems

Definition

Decision Support Systems (DSS) are computer-based information systems that assist in the decision-making process by analyzing large volumes of data, providing insights, and presenting information in a user-friendly format. They combine data, sophisticated analytical models, and sometimes user-friendly software to support the process of making decisions, especially in complex scenarios where various factors need to be considered.
