Heuristics and metaheuristics for heavily constrained hybrid flowshop problems

Urlings ., Thijs (Universitat Politècnica de València, 2010-07-16)

Due to the current trends in business as the necessity to have a large catalogue of products, orders that increase in frequency but not in size, globalisation and a market that is increasingly competitive, the production ...
Heuristics in optimal detailed design of precast road bridges

Yepes Piqueras, Víctor; Martí Albiñana, José Vicente; García Segura, Tatiana; González Vidosa, Fernando (2017)

[EN] This paper deals with the cost optimization of road bridges consisting of concrete slabs prepared in situ and two precast-prestressed U-shaped beams of self-compacting concrete. It shows the efficiency of four heuristic ...
Iterated Greedy methods for the distributed permutation flowshop scheduling problem

Ruiz García, Rubén; Pan, Quan-Ke; Naderi, Bahman (Elsevier, 2019-03)

[EN] Large manufacturing firms operate more than one production center. As a result, in relation to scheduling problems, which factory manufactures which product is an important consideration. In this paper we study an ...
Local search methods for the flowshop scheduling problem with flowtime minimization

Quan-Ke Pan; Ruiz García, Rubén (Elsevier, 2012-10-01)

Flowshop scheduling is a very active research area. This problem still attracts a considerable amount of interest despite the sheer amount of available results. Total flowtime minimization of a flowshop has been actively ...
METAHEURISTIC ANALYSIS IN REVERSE LOGISTICS OF WASTE

Serrano Elena, Antonio (Editorial Universitat Politècnica de València, 2016-06-01)

[EN] This paper focuses in the use of search metaheuristic techniques on a dynamic and deterministic model to analyze and solve cost optimization problems and location in reverse logistics, within the field of municipal ...
Modelizado para la planeación de la producción y la logística directa e inversa de una cadena de suministro cuyo abastecimiento depende parcialmente de los materiales de retorno

Parra Peña, Javier (Universitat Politècnica de València, 2016-11-10)

[EN] In this Thesis, we analyze an industry type that has two basic features: Its products are distributed in a geographic level and it reuses material after that is consumed to made new products. Because of these features, ...
New Heuristic Algorithms for the Windy Rural Postman Problem

Benavent, E.; Corberán, A.; Piñana, E.; Plana. I.; Sanchís Llopis, José María (Elsevier, 2005)

[EN] In this paper we deal with the windy rural postman problem. This problem generalizes several important arc routing problems and has interesting real-life applications. Here, we present several heuristics whose study ...
Optimization and Robustness in Planning and Scheduling Problems. Application to Container Terminals

Rodríguez Molins, Mario (Universitat Politècnica de València, 2015-03-31)

Despite the continuous evolution in computers and information technology, real-world combinatorial optimization problems are NP-problems, in particular in the domain of planning and scheduling. Thus, although exact ...
Production scheduling in no-‐idle environments

Piérola Orcero, Ana (Universitat Politècnica de València, 2016-11-02)

[EN] This MSc. Thesis gathers the description, implementation and evaluation of heuristic and metaheuristic scheduling methods in no-‐idle production environments
Secuenciación de máquinas con necesidad de ajustes y recursos adicionales.

Yepes Borrero, Juan Camilo (Universitat Politècnica de València, 2021-01-10)

[ES] En esta tesis doctoral se estudia el problema de secuenciación de máquinas paralelas no relacionadas con necesidad de ajustes y recursos adicionales asignados en los ajustes. En este problema, se tiene un grupo de ...
Sistema para la optimización del corte en línea de float

Adrià Bohigues, Vicente (Universitat Politècnica de València, 2016-09-13)

[ES] En este TFG se aborda el problema real del procesado de materia prima, desde un origen en forma de material continuo o bobinas gigantes hasta un formato más maleable en forma de láminas rectangulares. Ejemplos de estas ...
