This is an introductory text for Operations Research with focus on methods used to solve Linear Programming Problems (LPP). It provides a reader an easy-understanding of problem-solving methods based upon careful discussion of model formulation, solution procedures and analysis. It further discuss the use of computer packages (LINDO) to solve the LPP. The entire book is divided into 6 chapters, which contains the following: 1.General Concept of Operation Research 2.Linear Programming Problem/Model 3.Graphical Method 4.Simplex Method 5.Duality in Linear Programming 6.Sensitivity Analysis in Linear Programming The book is intended to serve as a textbook for students of B.Sc (Education, Computer Science and Statistics) , BBA who need to understand the basic concepts of Operations Research and apply them. It also suits the requirement for MBA, MSc (Mathematics, Information Technology and Statistics) who need both theoretical and practical knowledge of Operations Research.
