Mathematical models and a heuristic method for the multiperiod one-dimensional cutting stock problem
(2016-03-01)
The multiperiod cutting stock problem arises in the production planning and programming of many industries that have the cutting process as an important stage. Ordered items are required in different periods of a finite ...
Integrated lot-sizing and one-dimensional cutting stock problem with usable leftovers
(2020-01-01)
This paper addresses the integration of the lot-sizing problem and the one-dimensional cutting stock problem with usable leftovers (LSP-CSPUL). This integration aims to minimize the cost of cutting items from objects ...
The one-dimensional cutting stock problem with usable leftovers - A survey
(Elsevier B.V., 2014-07-16)
In this article, we review published studies that consider the solution of the one-dimensional cutting stock problem (1DCSP) with the possibility of using leftovers to meet future demands, if long enough. the one-dimensional ...
The integrated lot sizing and cutting stock problem in an automotive spring factory
(2021-03-01)
In this paper, a manufacturer of automotive springs is studied in order to reduce inventory costs and losses in the steel bar cutting process. For that, a mathematical model is proposed considering parallel machines and ...
Heuristics for the one-dimensional cutting stock problem with limited multiple stock lengths
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
This paper deals with the classical one-dimensional integer cutting stock problem, which consists of cutting a set of available stock lengths in order to produce smaller ordered items. This process is carried out in order ...

One-dimensional multi-period cutting stock problems in the concrete industry
(2021-01-01)
This research looks at the production planning of hollow-core slabs integrated to the optimisation problem of the use of moulds. Considering the production process of these structures, two mathematical models are proposed ...
A GENETIC ALGORITHM FOR THE ONE-DIMENSIONAL CUTTING STOCK PROBLEM WITH SETUPS
(Sociedade Brasileira de Pesquisa Operacional, 2014-05-01)
This paper investigates the one-dimensional cutting stock problem considering two conflicting objective functions: minimization of both the number of objects and the number of different cutting patterns used. A new heuristic ...
