This research project deals with problems that appear in different industrial contexts. An important part of industrial production planning comprises solving the lot sizing problem, which consists of determining the decisions regarding the quantities of end products to be produced in each period over a planning horizon of finite and discrete time. In several manufacturing systems, the pro…
The Cutting Stock Problem (CSP) consists in determining the best way to cut bigger objects into small items, and it has been studied for decades. CSP is found in many industrialprocesses, and part of its actual research has focused on extensions and integrations of this problem with other operational aspects found in real industrial systems, for instance, lot sizing and alternative manufa…
The lot sizing problem consists in determining the quantity of products to be produced in each period over a finite time horizon in order to meet a certain demand and optimize an objective function, such as minimizing costs. With the natural evolution of the industrial decisions process, several strategies have been used to improve the decisions made, making them more complex. Among these…
In some industrial sectors, the lot sizing is strongly related to other important decisions of the production process. Such decisions can be made independently of lot size decisions or integrated using a mathematical model that simultaneously captures the relationships between problems. Within this updated context, and motivated by the technical and economic importance of the practical ap…

This research project focuses on industrial production planning problems that involve blending components to assemble end products, where the proportion of components used in the final composition can vary. The objective is to yield plans that minimize overall costs of blending components to meet external demand of end products. The plans also need to consider capacity time constraints an…
This research project aims to study arc-flow formulations and solutions methods applied to cutting stock problems. We intend to investigate extensions of problems inspired by industrial applications in which their actual solution methods lack improvements. To improve its computational performance, we propose to reformulate these problems using state-of-the-art arc-flow formulations. Arc-f…
In this research project, the main goal is to provide an updated literature review on modeling integrated of lot sizing problems. A secondary goal is to introduce new heuristic approaches for such integrated problems which can provide a high-quality solution in a small computational time. In particular, strategies based on heuristics will be addressed as, e.g., relax-and-fix, fix-and-opti…
In this research project we intend to investigate extensions of lot sizing problems, as well as their integrations. Regarding integrations, the main focus will be to investigate the integrated lot sizing and cut stock problem, that consists in an optimization problem that considers simultaneously decisions related to the lot sizing problem and to the cutting stock problem. The goal is to …
As expected, up to the present stage of the post-doc, we have initiated the studies of flexibility to lot sizing problems. The first source of flexibility that we are working is the machine flexibility. In the standard lot sizing problem on parallel machines, each item can be produced on any of the machines and incurs a setup cost and time before production. In this case we have complete …
