The applications and computations in operations research are emphasized. Significantly revised, this text streamlines the coverage of the theory, applications, and computations of operations research. Numerical examples are effectively used to explain complex mathematical concepts. 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. New materials include Markov chains, TSP heuristics, new LP models, and a totally new simplex-based approach to LP sensitivity analysis.

    For every General Electric–still going strong after more than one hundred years–there are dozens of businesses like Central Leather, which was one of the world’s largest companies in 1912 but was liquidated in 1952. Ormerod debunks conventional economic theory–that the world economy ticks along in perfect equilibrium according to the best-laid plans of business and government–and delves into the reasons for the failure of brands, entire companies, and public policies. Inspired by recent advances in evolutionary theory and biology, Ormerod illuminates the ways in which companies and policy-setting sectors of government behave much like living organisms: unless they evolve, they die. But he also makes clear how desirable social and economic outcomes may be achieved when individuals, companies and governments adapt in response to the actual behavior and requirements of their customers and constituents.Why Most Things Fail is a fascinating and provocative study of a truth all too seldom acknowledged.

    Why is it better to buy a lottery ticket on a Friday? Why are showers always too hot or too cold?
