Decision Support Systems
Midterm Exam
Course Introduction
Decision Support Systems (DSS) explores the concepts, design, implementation, and application of computerized systems that support complex decision-making and problem-solving processes in organizations. The course introduces students to the components and types of DSS, including data management, models, user interfaces, and knowledge-based systems. Students will examine how DSS integrates data, sophisticated analytical models, and interactive tools to support structured and unstructured decision scenarios. Emphasis is placed on real-world case studies, the impact of DSS on organizational effectiveness, and emerging technologies such as artificial intelligence and machine learning in decision support. By the end of the course, students will be able to design and evaluate DSS to improve managerial and operational decision-making.
