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 ...
Article
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 ...
Article
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 ...

Using real-time information to reschedule jobs in a flowshop with variable processing times
(Elsevier, 2019-03)
In a time where detailed, instantaneous and accurate information on shop-floor status is becoming available in many manufacturing companies due to Information Technologies initiatives such as Smart Factory or Industry 4.0, ...

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 ...
Article
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, ...

Efficiency of the solution representations for the hybrid flow shop scheduling problem with makespan objective
(Elsevier, 2019)
In this paper we address the classical hybrid flow shop scheduling problem with makespan objective. As this problem is known to be NP-hard and a very common layout in real-life manufacturing scenarios, many studies have ...

A new set of high-performing heuristics to minimize flowtime in permutation flowshops
(Elsevier, 2015)
This paper addresses the problem of scheduling jobs in a permutation flowshop with the objective of total completion time minimisation. Since this problem is known to be NP-hard, most research has focussed on obtaining ...
