Decision Support Systems (DSS) are computer-based tools that help people analyse information and make decisions. They use data from various sources, like databases and spreadsheets, to provide insights and recommendations. DSS are valuable in business and management, where they assist in complex decision-making processes by processing large amounts of data quickly and accurately. They can simulate scenarios, perform calculations, and visualise data to help users understand trends and predict outcomes. By integrating advanced analytics and modelling techniques, DSS enables users to evaluate different options and choose the best course of action based on objective data analysis. This makes DSS essential tools for organisations seeking to improve decision-making efficiency and effectiveness across various industries. This book includes some of the vital pieces of work being conducted across the world, on various topics related to decision support systems. It brings forth some of the most innovative concepts and elucidates the unexplored aspects of decision support systems. It aims to serve as a resource guide for students and experts alike and contribute to the growth of the discipline.
