A computational evaluation of constructive and improvement heuristics for the blocking flow shop to minimize total flowtime
(Elsevier, 2016)
This paper focuses on the blocking flow shop scheduling problem with the objective of total flowtime minimisation. This problem assumes that there are no buffers between machines and, due to its application to many ...

Integrated Project Scheduling and Staff Assignment with Controllable Processing Times
(Hindawi Publishing Corporation, 2014)
This paper addresses a decision problem related to simultaneously scheduling the tasks in a project and assigning the staff to these tasks, taking into account that a task can be performed only by employeeswith certain ...

Robust optimization of alginate-Carbopol 940 bead formulations
(Hindawi Publishing Corporation, 2012)
Formulation process is a very complex activity which sometimes implicates taking decisions about parameters or variables to obtain the best results in a high variability or uncertainty context. Therefore, robust optimization ...

Efficient constructive and composite heuristics for the Permutation Flowshop to minimise total earliness and tardiness
(Elsevier, 2016)
In this paper we address the problem of scheduling jobs in a permutation flowshop with a just-in-time objective, i.e. the minimisation of the sum of total tardiness and total earliness. Since the problem is NP-hard, there ...

The Permutation Flow Shop Scheduling Problem with Human Resources: MILP Models, Decoding Procedures, NEH-Based Heuristics, and an Iterated Greedy Algorithm
(MDPI, 2022-09-22)
In this paper, we address the permutation flow shop scheduling problem with sequence-dependent and non-anticipatory setup times. These setups are performed or supervised by multiple servers, which are renewable secondary ...

A bounded-search iterated greedy algorithm for the distributed permutation flowshop scheduling problem
(Taylor & Francis, 2014)
As the interest of practitioners and researchers in scheduling in a multi-factory environment is growing, there is an increasing need to provide efficient algorithms for this type of decision problems, characterised by ...

Sobre la modernización de los vehículos blindados y su relación con el coste de ciclo de vida
(CISDE, 2017)
La decisión de afrontar un gran programa de adquisiciones para la defensa suele tener muy presente los costes que supone. Si bien en ocasiones tal decisión queda delimitada a la consideración de costes de adquisición, ...

Reduction of permutation flowshop problems to single machine problems using machine dominance relations
(Elsevier, 2017)
The Permutation Flowshop Scheduling Problem with Makespan objective (PFSP-M) is known to be NP-hard for more than two machines, and literally hundreds of works in the last decades have proposed exact and approximate ...

A European Assessment of the Solar Energy Cost: Key Factors and Optimal Technology
(MDPI, 2021-03)
Solar energy has become one of the most important sources of energy all around the world. Only in the European Union, between 2010 and 2019, solar photovoltaic (PV) electricity generation capacity increased from 1.9 to ...

XPDRL project: Improving the project documentation quality in the Spanish architectural, engineering and construction sector
(Elsevier, 2010)
In this paper we discuss the results of a research project called eXtensible Project Documentation Reporting Language (XPDRL). The main objective of this project is to improve the quality of the core project documentation ...
