речь о (продольной) разрезке (рулонов).

The trimming process in a paper mill, where winder cutting patterns are generated from the mix of orders to be manufactured, has primarily been considered a one-time, user-initiated event. For the typical trim solution, a production planner will execute a computer-based linear programming (LP) or heuristic trim algorithm after all orders in a manufacturing block are known and as the actual production date approaches. Most planners trim between one and four days in advance of the manufacture date. Trimming too far in advance risks rework if customers change ordered quantities or sizes.

Trim algorithms, because of their computational nature, consume large amounts of computer processing time. In the past, running a trim algorithm was slow and could affect the performance of an entire system. \
