The Cutting Pattern Planning System

One of the great strengths of the system is that it is capable of optimising both sheet and roll orders. Indeed, some paper machines allow for a mixture of sheet and roll cutting plans to be input into the production program at the same time.

In the course of cutting planning, the system is able to cut together orders of different qualities if the quality parameter tolerances overlap to the extent that the narrow cross section still gives a technologically feasible cutting plan.

Of course, the program will only generate such combinations where there are no other alternatives.

Given the right parameters, the system’s algorithm will utilize only the absolutely necessary amount of raw material to realise the given task. In order to achieve an optimal solution, the cutting plan is able to display what quantity from which order is necessary to be produced in advance of the originally scheduled production time.

Sheet cutting planning automatically takes into account the effect of sheet sizes on cross-cut productivity indicators, and then accordingly tabulates and switches orders.

The entire process of cutting planning requires just a few minutes in the case of an entire weekend program to be constructed because the system executes the cutting planning of all planned qualities in a single operation.
