Decision support is a field of research that focuses on developing tools, systems, and techniques to help individuals and organizations make more effective decisions. This area of study typically involves the use of data analysis, modeling, and simulation to provide decision-makers with relevant information and insights that can guide their decision-making processes. Decision support systems (DSS) are often used in various industries and sectors, such as business, healthcare, and government, to assist with complex decision-making tasks. These systems can help users analyze data, evaluate alternative courses of action, and assess potential outcomes to make more informed decisions. Researchers in the field of decision support often explore topics such as decision-making processes, information systems, data visualization, and decision analysis. By developing and refining decision support tools and methodologies, researchers aim to improve the quality and efficiency of decision-making processes in various contexts.
