Excel OM is Prentice Hall's exclusive user-friendly Excel add-in. Excel OM automatically creates worksheets to model and solve problems. Students select a topic from the pull-down menu, fill in the data, and then Excel will display and graph (where appropriate) the results. This software is great for student homework, "what if" analysis, or classroom demonstrations. Extend+ is a graphic simulation program that allows you to build dynamic models and systems. A limited version of Extend+ is included on the CD. This version contains 10 manufacturing and service models that correspond to chapter topics. These models are described in Word documents and can be used for homework, team projects, or classroom demonstrations. The limited version of Extend+ is an excellent package for demonstrating operations processes and teaching simulation. Extensive Lecture Notes provide reinforcement of the main points of each chapter and allow students to review the chapter material. The Lecture Notes are available in both a slide-show format, with audio clips, for in-class viewing, and in a printable format to be used as a helpful study guide. Quizzes allow students to test their understanding of each chapter. Exercises: Miami Rec Center.
