Version 2.4.0 of Decision Modeling is available for free pdf download from:
This book 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.
Since Version 2.3.2, I have re-written Chapter 1, which has caused a change to the solution to Question 2 at the end of Chapter 1. The revised solutions to Chapter 1 are attached. Solutions to all the end-of-chapter problems (nine pdf files) can be requested by contacting me at firstname.lastname@example.org.
