A pre-pandemic analysis of the global fertiliser trade network
(Elsevier, 2023)
In this paper a complex network analysis of global fertiliser trade during the period 2014–2018 has been carried out. The goal is to study its structure both at the global and local level, identifying communities and ...

A decision-making model to design a sustainable container depot logistic network: the case of the port of Valencia
(Vilnius Gediminas Technical University Press, 2018)
In this paper, the design of a maritime container depot logistic network in a hinterland is studied. Containers are a basic tool in multimodal product transportation and all related operations have an impact on the ...

Data Envelopment Analysis Approach to Energy-Saving Projects Selection in an Energy Service Company
(MDPI, 2021-01-19)
Project selection is a common problem for many companies. Specifically, it consists in identifying which projects should be selected with regard to their economic efficiency, i.e., the projects that maximise the profit ...

Setting a common due date in a constrained flowshop: A variable neighbourhood search approach
(2010)
In this paper we study a due date setting problem in a flowshop layout. The problem consists of scheduling a set of jobs arriving to the system together with jobs already present (denoted as old jobs), in order to set a ...

Increasing Sustainability of Logistic Networks by Reducing Product Losses: A Network DEA Approach
(Hindawi Limited, 2018)
This paper considers a multiproduct supply network, in which losses (e.g., spoilage of perishable products) can occur at either the nodes or the arcs. Using observed data, a Network Data Envelopment Analysis (NDEA) approach ...

A novel integrated fuzzy DEA–artificial intelligence approach for assessing environmental efficiency and predicting CO2 emissions
(Springer, 2023)
Undesirable output of industrial economic activities—carbon dioxide (CO2) and other pollutants—has been become global concern because of their harmful effects on the climate, especially for environmentally sustainable ...

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 ...

Efficient heuristics for the hybrid flow shop scheduling problem with missing operations
(Elsevier, 2019)
In this paper, we address the hybrid flowshop scheduling problem for makespan minimisation. More specifically, we are interested in the special case where there are missing operations, i.e. some stages are skipped, a ...

Serial vs. 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, ...

A review and classification of computer-based manufacturing scheduling tools
(Elsevier, 2016)
Computer-based manufacturing scheduling tools can play a key role in the management of industrial operations, as obtaining economic and reliable schedules is at the core of excellence in customer service and of efficiency ...
