For junior/senior undergraduate and first-year graduate courses in Operations Research in departments of Industrial Engineering, Business Administration, Statistics, Computer Science, and Mathematics.
Theory, applications, and computations.
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.
The companion Excel, TORA, and AMPL files as well as the additional chapters and appendixes are available on the Taha Companion Website (www.pearsonhighered.com/taha) that includes valuable resources forboth students and instructors. A note about accessing the Companion Website:
Instructors should click the "Register" link and follow the on-screen directions to access the site. Instructors need a Pearson Education account to register, but do not require an additional Access Code.
Students can access the Companion Website by redeeming the Access Code included in the front of their new copy of Operations Research, 9e. Students can also purchase Companion Website access online.
The Instructor Resource Center contains the Solutions Manual and PowerPoints of the art from the book. Instructors can download these resources from www.pearsonhighered.com/irc
