"Wire cutting" is a common type of production problem. That is, given available stock of wire (or other one-dimensional stock material) and a list of pieces required, what is the best way to cut the stock to fulfil the requirements while minimizing waste?
The benefits from improved cutting can be substantial, while poor cutting choices can be expensive. To illustrate how an optimization model can help us make the decision, in this article we design, build, and solve a wire cutting problem using OpenSolver.
