Serial versus divergent supply chain networks: a comparative analysis of the bullwhip effect
(Taylor & Francis, 2014)
The amplification of demand variation in a supply chain network (SCN) is a well-known phenomenon called the bullwhip effect, which creates inefficiencies due to high variation in the order quantities placed between companies, ...

Single machine scheduling with periodic machine availability
(Elsevier, 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 ...

The heterogeneous vehicle routing problem with time windows and a limited number of resources
(Elsevier, 2020-09)
This paper introduces the heterogeneous vehicle routing problem with time windows and a limited number of resources (HVRPTW-LR), a practical extension of the classical vehicle routing problem in which routes to be designed ...

Advanced Techniques for Assets Maintenance Management
(IFAC (International Federation of Automatic Control) - Elsevier, 2018)
The aim of this paper is to remark the importance of new and advanced techniques supporting decision making in different business processes for maintenance and assets management, as well as the basic need of adopting a ...

On bullwhip-limiting strategies in divergent supply chain networks
(Elsevier, 2014-07)
The amplification of demand variation in a supply chain network (SCN) is a well-known phenomenon called the bullwhip effect. This effect generates a large volume of inefficiencies as it moves a greater number of units than ...

Building Information Modeling as Assest Management Tool
(Elsevier, 2016)
BIM models are transforming the way buildings or, in more general terms, facilities or infrastructures are conceived, designed, constructed and managed. But current use of BIM concentrates on preplanning, design, construction ...

Information sharing in supply chains with heterogeneous retailers
(Elsevier, 2018)
This work analyses partial information sharing involving retailers with different operational configurations. Retailers are characterized by four operational factors, i.e., demand variance, lead time average, forecasting ...

A Model for Lifecycle Cost Calculation Based on Asset Health Index
(ICE Publishing, 2019)
During many years, asset management methodologies used in industry were focused on knowing and analysing the operational control of the daily work and the impact of the maintenance on the availability. Later, the costs ...

Iterated-greedy-based algorithms with beam search initialization for the permutation flowshop to minimize total tardiness
(Elsevier, 2018)
The permutation flow shop scheduling problem is one of the most studied operations research related problems. Literally, hundreds of exact and approximate algorithms have been proposed to optimise several objective functions. ...

Permutation flowshop scheduling with periodic maintenance and makespan objective
(Elsevier, 2020-05)
In this paper, we address the permutation flowshop scheduling problem with cyclical unavailability periods where no operation can be processed. Under this constraint, all machines must stop at the same time due to the shift ...
