The objective of management science is to solve the decision-making problems that confront and confound managers in both the public and the private sector by developing mathematical models of those problems. These models have traditionally been solved with various mathematical techniques, all of which lend themselves to specific types of problems. Thus, management science as a field of study has always been inherently mathematical in nature, and as a result sometimes complex and rigor- ous. When I began writing the first edition of this book in 1979, my main goal was to make these mathematical top- ics seem less complex and thus more palatable to under- graduate business students. To achieve this goal I started out by trying to provide simple, straightforward explana- tions of often difficult mathematical topics. I tried to use lots of examples that demonstrated in detail the funda- mental mathematical steps of the modeling and solution techniques. Although in the past three decades the empha- sis in management science has shifted away from strictly mathematical to mostly computer solutions, my objective has not changed. I have provided clear, concise explana- tions of the techniques used in management science to model problems, and provided many examples of how to solve these models on the computer while still including some of the fundamental mathematics of the techniques.
The stuff of management science can seem abstract, and students sometimes have trouble perceiving the use- fulness of quantitative courses in general. I remember that when I was a student, I could not foresee how I would use such mathematical topics (in addition to a lot of the other things I learned in college) in any job after graduation. Part of the problem is that the examples used in books often do not seem realistic. Unfortunately, examples must be made simple to facilitate the learning process. Larger, more complex examples reflecting actual applications would be too complex to help th
