Free Open-Source Models
Embedded Files
Number Engine provides the general public with some open-source spreadsheet models. These models can be used with the Optimization Solver app to model and optimize various business operations. They can also be a good starting point to introduce you to modeling.
Check them out below! All models are completely free & open-source, subject to the MIT License. If you'd like to see a new model added that isn't available below, contact us about your idea.
Supported Functions
The Number Engine add-on supports optimization with many spreadsheet functions. Please see below for a comprehensive list of all 378 of them:
*Note that the linear solution method has some restrictions on functions with piecewise or discontinuous behavior, but the nonlinear solution method supports optimization with all of the functions below*
