Overview

A solution to the steel mill problem can be determined using CP Optimizer and the three-stage method of describe, model and solve.

In this lesson, you will learn how to:

• use the specialized constraint IloPack;

• use the specialized constraint IloOr;

• use search phases to direct the search.

You will learn to model and solve a problem regarding selecting steel slabs of various sizes and assigning a batch of steel coil orders to the selected slabs. This problem is based on problem 38 in the CSP Library (www.csplib.org). To find an optimal solution to this problem using CP Optimizer, you will use the three-stage method: describe, model and solve.
