Management Science
Midterm Exam
Course Introduction
Management Science is a discipline that applies quantitative and analytical methods to assist decision-making within organizations. The course covers a range of mathematical modeling techniques, including linear programming, decision analysis, simulation, forecasting, and network models, to solve complex business problems and improve operational efficiency. Students will learn to use software tools for model formulation and analysis, interpret results to support managerial decisions, and understand the limitations and ethical considerations of these approaches. By integrating theory with real-world case studies, the course prepares students to apply scientific principles and data-driven strategies to management challenges in diverse industries.
