Flexible Stock Allocation and Trim Loss Control for Cutting Problem in the Industrial-Use Paper Production

الملخص EN

We consider a one-dimensional cutting stock problem (CSP) in which the stock widths are not used to fulfill the order but kept for use in the future for the industrial-use paper production.

We present a new model based on the flexible stock allocation and trim loss control to determine the production quantity.

We evaluate our approach using a real data and show that we are able to solve industrial-size problems, while also addressing common cutting considerations such as aggregation of orders, multiple stock widths, and cutting different patterns on the same machine.

In addition, we compare our model with others, including trim loss minimization problem (TLMP) and cutting stock problem (CSP).

The results show that the proposed model outperforms the other two models regarding total flexibility and trim loss ratio.
