A new vision of approximate methods for the permutation flowshop to minimise makespan: State-of-the-art and computational evaluation
(Elsevier, 2017)
The permutation flowshop problem is a classic machine scheduling problem where n jobs must be processed on a set of m machines disposed in series and where each job must visit all machines in the same order. Many production ...

Decision support systems for task scheduling: applications in manufacturing and healthcare
(2017)
Esta Tesis se centra en el problema de la programación de tareas. Aunque pueden encontrarse diferentes definiciones de la programación de tareas en la literatura, aquí se define como la asignación de un número de tareas – ...

Inventory record inaccuracy – The impact of structural complexity and lead time variability
(Elsevier, 2017)
This article presents a rigorous prospective analysis of the impact of Inventory Record Inaccuracy (IRI) on complex multi-echelon Supply Chains (SCs). Specifically, key operational factors (i.e., the magnitude of the error, ...

An approach to quantify value provided by an engineered asset according to the ISO 5500x series of standards
(2017)
The purpose of any asset is to provide value to the organization and its stakeholders. In Asset Management, the concept of value encompasses quantitative and qualitative, as well as tangible and intangible benefits that ...

A beam-search-based constructive heuristic for the PFSP to minimise total flowtime
(Elsevier, 2017)
In this paper we present a beam-search-based constructive heuristic to solve the permutation flowshop scheduling problem with total flowtime minimisation as objective. This well-known problem is NP-hard, and several ...

Aproximación cualitativa al concepto de valor durante el ciclo de vida de un activo industrial
(Asociación Española para la Calidad (AEC), 2017-11)
La familia de normas ISO 5500x establece el “Valor” como uno de los conceptos clave en la gestión de activos. Según esta norma, el activo es la entidad que tiene o genera valor para la organización, y la definición ...

New approximate algorithms for the customer order scheduling problem with total completion time objective
(Elsevier, 2017-02)
In this paper, we study a customer order scheduling problem where a number of orders, composed of several product types, have to be scheduled on a set of parallel machines, each one capable to process a single product type. ...

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 ...
