This widely-adopted text presents an accessible introduction to the techniques and applications of management science. It is designed to make the subject easily understandable and interesting for students with limited mathematical backgrounds or skills. The author focuses on management science not only as a collection of techniques and processes, but as a philosophy and method for approaching problems in a logical manner. It includes Excel spreadsheets with solutions in every chapter, and many examples of how to solve management science models on the computer.
This was the textbook for my MBA course on scientific management techniques. It was a few years ago, so the content is a bit hazy. I do remember the text being good, however.
