Integrated lot-sizing and cutting stock problem applied to the mattress industry
(2020-01-01)
In many productive processes, two important problems arise in the production planning: the lot-sizing problem and the cutting stock problem. Generally, companies deal with these problems separately but, by considering them ...
Strategies to model scheduling decisions to plan the soft drink production process
(2012-06-13)
In this paper we present a mixed integer model that integrates lot sizing and lot scheduling decisions for the production planning of a soft drink company. The main contribution of the paper is to present a model that ...
Optimization Of An Integrated Lot Sizing And Cutting Stock Problem In The Paper Industry

The combined cutting stock and lot-sizing problem in industrial processes
(Elsevier Science BvAmsterdamHolanda, 2006)
Integrated lot sizing and blending problems
(2021-07-01)
The standard blending problem consists of combining components to produce a final product with a given demand, while satisfying specific criteria with respect to the global blend and minimizing the total cost. The ...
A hybrid heuristic approach to solve the multi level capacitated lot sizing problem
(2011-08-29)
This paper presents preliminary results found by a hybrid heuristic applied to solve the Multi-Level Capacitated Lot Sizing Problem (MLCLSP). The proposed method combines a multi-population genetic algorithm and fix-and-optimize ...
Mathematical model and solution approaches for integrated lot-sizing, scheduling and cutting stock problems
(Springer, 2020-09-04)
In this paper, we address a two-stage integrated lot-sizing, scheduling and cutting stock problem with sequence-dependent setup times and setup costs. In production stage one, a cutting machine is used to cut large objects ...
The integrated lot sizing and cutting stock problem in a furniture factory
(2013-08-08)
This work studies the integrated lot sizing and cutting stock problem, where the goal is to capture the dependency that exists between two important decisions in the production process, in order to economize raw materials ...
A Lagrangian relaxation approach to a coupled lot-sizing and cutting stock problem
(Elsevier B.V., 2009-06-01)
Industrial production processes involving both lot-sizing and cutting stock problems are common in many industrial settings. However, they are usually treated in a separate way, which could lead to costly production plans. ...
