This seventh edition continues to build on the strength of the first six editions, providing balanced coverage of the theory, applications, and computations of operations research. Complex mathematical concepts are effectively explained by means of carefully designed numerical examples, essentially eliminating the need for the usually obscure formal mathematical proofs. The book includes fully analyzed practical situations and each chapter concludes with summary applications borrowed from published case studies. The role of modern computational tools in enhancing the effectiveness of operations research as a decision-making tool receives considerable attention in this new edition. New for the Seventh Edition: *Practically every algorithm in the book is now supported and explained by an appropriate software tool, greatly facilitating the process of explaining concepts that otherwise would be difficult, if not impossible, to demonstrate. *The powerful Windows -based TORA software offers new and unique tutorial features, ranging from animated graphical LP solution to dynamic construction of CPM time charts and generation of branch-and-bound search trees. *For the first time, Excel te
