A Decision-Making Tool for a Regional Network of Clinical Laboratories
(INFORMS, 2013)
For healthcare systems that operate in large, geographically dispersed areas, the quality of the services provided requires the effective management of a complex transportation problem. We present a decision support ...

NEH-based heuristics for the permutation flowshop scheduling problem to minimize total tardiness
(Elsevier, 2015)
Since Johnson׳s seminal paper in 1954, scheduling jobs in a permutation flowshop has been receiving the attention of hundreds of practitioners and researchers, being one of the most studied topics in the Operations Research ...

Capacity restrictions and supply chain performance: Modelling and analysing load-dependent lead times
(Elsevier, 2018)
Several studies have reported that capacitated supply chains may benefit from an improved dynamic performance as compared to unconstrained ones. This occurs as a consequence of the capacity limit acting as a production ...

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 ...

Los cuatro arquetipos de cadenas de suministro
(Portal Universia S.A., 2010)
A lo largo del siglo XX las cadenas de suministro han evolucionado para enfrentarse a los desafíos del mercado globalizado y librarse de ineficiencias congénitas como el efecto látigo. En este artículo se presentan cuatros ...

Single machine scheduling with periodic machine availability
(Elsevier Ltd, 2018-09)
In this paper we address the problem of scheduling jobs on a single machine with cyclical machine availability periods. In this problem, the scheduling horizon is composed of periods where the machine is available followed ...

Permutation flowshop problems with initial availability constraints: Characterisation and Analysis
(ADINGOR ( Asociación para el Desarrollo de la Ingeniería de Organización), 2010)
This paper characterises the initial availability constraint problems in a permutation flowshop layout considering different objectives: makespan, total flowtime and idle time. The goal is to analyse the structure ...

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, ...

The permutation flowshop scheduling problem: analysis, solution procedures and problem extensions
(2016-06-27)
During the past twenty five years, following the massive use of internet and the EU single Market, European manufacturing companies struggle in a more competitive market, where firms from different countries must fight for ...
