How many other optimal solutions exist? How do I find those solutions. This article explains how to use the CPLEX solution pool.
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?
Designing an optimization model is difficult. This article explains common mathematical notation used to define optimization model formulations.
Formulating logic conditions in linear programs can be difficult. This two-part article series explains how, using easy to follow steps.
We describe an example of how to represent price breaks in a linear programming model, built in Excel using Solver or OpenSolver.
This series of 13 articles compares Python libraries Pyomo, PuLP, OR-Tools, Gekko, CVXPY, and SciPy for building a linear programming model.
We've collated many interesting optimization models in our GitHub repository. The focus is on Excel and Python models.
Optimal facility location is a common & difficult decision that organizations need to make. We build a location optimization model in Excel.
