This paper is concerned with the classical two-dimensional cutting stock problem, whose solution consists of a set of cutting patterns that optimize an objective function, for example, the waste of material. Nevertheless, the cutting patterns have to be sequenced so that another criterion is also optimized, for example, the maximum number of open stacks of the items (a stack is opened when a type of item is cut for the first time and closed when all items of this type were cut). A good solution for the problem of generating cutting patterns often does not result in a good solution for the problem of sequencing cutting patterns, and vice-versa. In general, these two problems are treated, either in practice or in the literature, in an independent and successive way. Pileggi
