My free-to-download book called Decision Modeling covers the modeling of linear and integer programming, sensitivity analysis, goal and non-linear programming, and decision analysis. Problem solutions are obtained using both LINGO and the Excel Solver. The use of LINGO is in scalar mode, which avoids the use of sets, thereby making things easier for the intended audience of business students doing a survey course on optimization. Even if you are teaching an OR course which overlaps only part of the coverage of this pdf, you might wish to include it in a reading list. It is and will always remain a free resource.
Today a new version of Decision Modeling was issued. Version 3.2.5 can be downloaded for free from: https://linney.mun.ca/pages/view.php?ref=36808
The nine pdf files solutions files for the end-of-chapter problems can be requested by contacting me at dtulett@mun.ca.
(They have not changed since Version 3.1.0.)
