Spreadsheet Modeling and Decision Analysis (with CD-ROM and Microsoft Project 2003 120 day version)
In our opinion, Ragsdale has sufficient technical depth, including algebraic modeling, in all of the topics we teach (linear programming, decision analysis, queuing models, simulation, and forecasting).  The text is well written with a wide range of problems (easy to very difficult) from a variety of applications.[Ragsdale] has a very straightforward presentation of a difficult topic.  It is readable for students and useful for professors.
