A relax-and-fix with fix-and-optimize heuristic applied to multi-level lot-sizing problems
(2015-10-29)
In this paper, we propose a simple but efficient heuristic that combines construction and improvement heuristic ideas to solve multi-level lot-sizing problems. A relax-and-fix heuristic is firstly used to build an initial ...
Estudos em problemas de dimesionamento de lotes com preparações carryover e crossover
(Universidade Estadual Paulista (Unesp), 2017-03-13)
Os problemas de dimensionamento de lotes consistem em determinar a quantidade de itens que devem ser produzidos em todos os períodos de um horizonte de planejamento. Em geral, são considerados custos de produção, preparação ...
Problema da programação da produção de bebidas à base de frutas: modelos de otimização e métodos heurísticos
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia de Produção - PPGEPCâmpus São Carlos, 2017-07-03)
The present work aims to study the problem of the production scheduling optimization of fruit-based beverage, such as nectars and fruit flavoured drinks. This is a lot sizing and scheduling problem in two main production ...
Integrated planning for planting and harvesting sugarcane and energy-cane for the production of sucrose and energy
(Elsevier B.V., 2021-05-01)
The main products obtained from sugarcane for the global market are sugar, ethanol and energy. Although the demand for these products is high, in Brazil there is no longer space to expand sugarcane cultivation due to other ...
Modelos de otimização e métodos de solução para o planejamento de redes logísticas
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia de Produção - PPGEPCâmpus São Carlos, 2022-09-13)
Logistics Network Planning (LNP) involves decisions such as facility location, demand allocation, inventory, and transportation management. These decisions differ in terms of periodicity and frequency over the planning ...
Annual Operating Costs Minimization in Electrical Distribution Networks via the Optimal Selection and Location of Fixed-Step Capacitor Banks Using a Hybrid Mathematical Formulation
(Cartagena de Indias, 2022)
The minimization of annual operating costs in radial distribution networks with the optimal selection and siting of fixed-step capacitor banks is addressed in this research by means of a two-stage optimization approach. ...
