Students first... This will be a difficult course no matter which textbook you use. Having said that, I would say that the text is about average in terms of readability in comparison to other texts on the subject. There are plenty of realistic cases to illustrate basic decision/ management science concepts, as well as a very useful CD, with which I recommend that you become well-acquainted as the course moves forward. Not much has changed since the last edition, so you may be able to get by with a previous edition if the textbook (authored by Eppen). Be advised, however, that some of the chapter materials have been re-arranged, including the exercises at the end of each chapter.
For professors... You are probably already aware that this course can be challenging for the professor as well as the student, esp. with respect to how math-intensive you wish the course to be. I think Moore & Weatherford is an excellent text, but it is written as an advanced graduate text. I have been able to "tone it down" for undergraduates by accompanying it with a nice, soft, theory-oriented text on decision/ management science (featuring the teachings of Herbert Simon and some of the early decision science theorists). The text is accompanied with ample instructor resources including a very useful CD with solutions, decision science software. I would engage the students w/ the CD as early as possible. I have also found that the best exams for this course are take-home exams - give the students some moderately challenging decision models to formulate and solve, and focus your evaluation primarily on how well they are able to interpret the results and propose recommendations for decision makers, and secondarily on whether they were able to get the software to spit out the right answers.
Don't buy it if you can live without it.
