Introduction to Management Science, 2/e uses case studies, modeling, and a spreadsheet approach to teach management science. Unlike the authors more rigorous Operations Research, this book is expressly designed to make management science easier to learn for students at the introductory level. Pedagogical features new to the Second Edition include margin notes, solved end-of-chapter problems, and "How-to" instructions for the Excel mini-cases. In addition to the text itself, the Second Edition includes a professional version of Crystal Ball, the most widely used Excel add-on for computer simulation. This software includes OptQuest (an optimizer with simulation) as well as a forecasting module. Material on working with Crystal Ball is integrated into the text. Other technology supplements include Premium Solver, another Excel add-on for solving large nonlinear problems.
