Introduction to Operations Research

Introduction to Operations Research. Instructor: Prof. G. Srinivasan, Department of Management Studies, IIT Madras. Operations research is a field of study about optimizing performance under given constraints. Operations research also helps us develop models for decision making. The course covers topics on linear programming, graphical and algebraic solutions, simplex algorithm, duality, understanding the dual, solving LPs using solver, transportation problem and assignment problem.
