How many other optimal solutions exist? How do I find those solutions. This article explains how to use the CPLEX solution pool.
Why does my model find different solutions? Some solutions are better than others – how can that be true? How do I find the overall best solution?
We've collated many interesting optimization models in our GitHub repository. The focus is on Excel and Python models.
We present an example of project crashing using an optimization model to help the project manager decide what to do.
Given available stock of wire and a list of pieces required, what is the best way to cut the stock to fulfil demand while minimizing waste?
We experiment with the new Python in Excel feature, building and solving a linear program using the Python SciPy library.
Designing an optimization model is difficult. This article explains common mathematical notation used to define optimization model formulations.
This article series implements a staff scheduling model in Excel using OpenSolver, then in Python using Pyomo.
