Operations Research: An Introduction 9/e uses theory, applications, and computations to teach students the basics of OR:

●Numerical examples are effectively used to explain complex mathematical concepts, thus avoiding the use of complex notations and theorems.

●A separate chapter of fully analyzed applications aptly demonstrates the diverse use of OR.

●The popular commercial and tutorial software AMPL, Excel, Excel Solver, and Tora are used throughout the book to solve practical problems and to test theoretical concepts.

The book can be used conveniently in a survey course that encompasses all the major tools of operations research, or in two separate courses on deterministic and probabilistic decision-making.

Topics include Markov chains, TSP heuristics, new LP models, a simplex-based approach to LP sensitivity analysis, and more. The ninth edition also includes a dedicated chapter on the traveling salesperson, as well as, for the first time in any OR textbook, a (math-free) Section 3.7 explains how the different linear programming algorithms (simplex, dual simplex, revised simplex, and interior point) are “meshed” together to produce highly-successful commercial codes for solving LP in practice.
