New treatment of input modeling highlights difficulties and solutions for real applications. Updated examples of simulation experiment design and analysis are provided. More Excel examples and supplements enhance the material. A more realistic presentation of input modeling in Chapter 9. Emphasis on appropriate analysis within the confines of commercial products, and a supplementary Excel tool that adds to the capabilities of those products. — Addresses that some texts present advanced simulation analysis methods that cannot be used in practice if they are not included in the software the practitioner actually uses, or are not readily available as a supplementary tool.
