The problems focused in this thematic project were divided into: (A) cutting problems; (B) packing problems; (C) lot-sizing problems; (D) scheduling problems; (E) routing problems (F) location problems and (G) the integration of these problems. In addition to the study and development of mathematical models related to these problems, solution methods and algorithms to solve them will be d…
In 2007 the applicant has started to develop financial supported projects on lot sizing problems integrated to other problems of optimization of the productive system. The applicant has done several contributions on the integration of the lot sizing problem with the scheduling problem, with the cutting and packing problem and with decisions related to the transportation of the produced it…

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 view of the increasing competitiveness between industries, the search for efficient techniques to help the production planning is expanding, with the purpose of maximizing the productivity and improving the products quality. In this work, we approach the alveolar slabs planning production integrated to the optimization problem of the use of molds. Based on the production process of the…
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…
In some industries, decisions about the production activities needed to transform raw materials into final items in the most efficient way possible are closely related to decisions on the lots of final items that must be produced, and in this context, arises the lot sizing problem, which basically, consists of determining the production lot sizes (ie, quantities to be produced of each ite…

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 …
