This article series implements a staff scheduling model in Excel using OpenSolver, then in Python using Pyomo.

We've collated links to dozens of websites about optimization modelling. The links are organized into several categories.

We explore methods to decide the best order for positioning devices in a rack: enumerate, heuristic, constraint programming, and linear program.

This series explores optimization of a "picking warehouse" by improving the warehouse design and efficiency of the picking process.

We experiment with the new Python in Excel feature, building and solving a linear program using the Python SciPy library.

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 compare a linear programming model written using Julia/JuMP with the same model written using Python/Pyomo.

This article replicates and extends a transportation optimization model for managing a COVID-19 vaccination plan in Hong Kong.

We minimize trim waste in a paper manufacturing process. A theoretically perfect solution is impractical, so what can we do?

We present an example of project crashing using an optimization model to help the project manager decide what to do.

Job sequencing is a common problem. Excel Solver can help you make optimal job sequencing decisions to minimize cost.

Designing an optimization model is difficult. This article explains common mathematical notation used to define optimization model formulations.
