Abstract
Despite its broad range of industrial applications, the two-stage guillotine restriction has received very scant attention in the strip cutting literature. An integer linear programming model that is based on a special graph structure is devised for this strongly NP-hard problem. In addition to being easy to implement, the empirical study on a large set of instances from the literature and from real industrial world cases shows the efficiency of the proposed method while solving instances with high multiplicity factor.
