Version 3.3.0 of Decision Modeling

  • 1.  Version 3.3.0 of Decision Modeling

    Posted 05-01-2023 10:41

    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. This pdf has now had well over 40,000 downloads.

    On Monday, May 1 a new version of Decision Modeling was issued. Since Version 3.2.5, the section on the transshipment problem has been re-written, and I have standardized on using lower-case letters for variables in algebraic models, while using upper-case letters for variables in LINGO models. There are also a few miscellaneous changes throughout the book. Version 3.3.0 can be downloaded for free from: https://linney.mun.ca/pages/view.php?ref=36808

    The first seven of the nine pdf files solutions files for the end-of-chapter problems have been reformatted. For example, where an objective function was one column in a LaTeX tabular environment, I now spread this function across three columns using the \multicolumn command. Also, I have standardized on the writing the variables as in done in Version 3.3.0. All nine files can be requested by contacting me at dtulett@mun.ca.
