Green Warehousing: Improving Energy Efficiency Through Digitalisation
No full textIn a context of increasing challenges for the logistics industry, further amplified by recent
disruptions, warehouses have been achieving an ever-crucial role in value chains. This has led to a
significant evolution of logistics facilities over time, that have been transitioning from simple
storage centres into high-functional facilities, with high complexity, where numerous and
heterogeneous processes are performed to guarantee efficiency and service level fulfilment. Such
transition has deeply impacted on warehouses, often making them highly energy intensive. To cope with these changes, a wide range of digital technologies is now available and has started to be gradually introduced by companies at their logistics facilities to reduce energy consumption and improve the environmental sustainability of warehousing operations. However, on the academic side, although a growing number of papers have been found addressing the adoption of digital technologies at logistics facilities with an energy efficiency perspective, a clear overview of the solutions in place and their impact on warehousing processes has been largely neglected so far. This contribution aims at addressing this research gap by offering a state-of-the-art of the role of digital technologies in improving energy efficiency at logistics facilities. The study is based on a systematic review approach performed by means of the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) protocol. The research is part of a broader Italian funded PNRR Research project “Centro Nazionale per la Mobilità Sostenibile” (MOST) – Spoke 10 “Sustainable Logistics”. Results indicate that the impact of digital technologies on warehouse processes is still underexamined, and research has mainly focused on specific technical issues or single warehousing processes rather than providing a holistic approach. The study provides a comprehensive framework offering guidance for technology implementation. Implications are discussed and streams for future investigation are identified
The Role of Digital Technologies in Improving Energy Efficiency at Logistics Facilities: A State-of-the-Art
Full text linkThe logistics industry is facing increasing challenges that have been further amplified by recent disruptions. In this context, warehouses have been playing an ever-crucial role. They have been transitioning from simple storage centres into high-functional facilities where several and heterogeneous processes are performed to guarantee efficiency and service level fulfilment. These dramatic changes have often made them highly energy intensive. To cope with these changes, a wide array of digital technologies is now available and has started to be gradually introduced by companies at their logistics facilities to reduce energy consumption and improve the environmental sustainability of warehousing operations. Nevertheless, on the academic side, although a mounting number of papers have been found addressing the adoption of digital technologies at logistics facilities with an energy efficiency perspective, a clear overview of the solutions in place and their impact on warehousing processes has been largely neglected so far. This contribution aims at addressing this research gap by offering a state-of-the-art of the role of digital technologies in improving energy efficiency at logistics facilities.

Green warehousing practices: Assessing the impact of PV self-consumption enhancement strategies in a logistics warehouse
Full text linkLogistics facilities, while critical to industrial systems, significantly contribute to greenhouse gas emissions, necessitating improved operations, energy use, and renewable energy integration. The use of distributed renewable energy sources, with their intermittent and unpredictable generation, disrupts energy balance and leads to curtailment issues. This places a significant load on the electrical grid, increasing emissions and environmental problems, hindering the effective use of renewable energy. To address these challenges, modifications can be made to existing warehouses to increase their self-consumption. Empirical studies assessing the impact of such modifications, particularly in the logistics field, are lacking. This work contributes to the ongoing research by proposing a simulation-based approach that evaluates multiple scenarios for a real-world logistics facility to enhance the self-consumption ratio. This analysis is based on a conceptual framework providing a roadmap towards sustainable warehousing practices. The study simulates and presents multiple scenarios, including the base case, electrification of the heating system, and an opportunity charging strategy for MHE, aiming to enhance self-consumption, while examining environmental and economic performances, followed by a sensitivity analysis. Findings demonstrate a 25% increase in self-consumption and significant energy consumption reduction (-110 MWh/year) and CO2e emissions (-67.8 tons CO2e/year) for the final proposed scenario
Sustainable and Energy-Efficient Industrial Systems: Modelling the Environmental Impact of Logistics Facilities
Full text linkIn the last decade industrial systems have been affected by increased challenges, and among those the need for more sustainable production and logistics has been called into question by both practitioners and academia. Within industrial networks, logistics facilities traditionally represent key nodes as they have a direct impact on both companies’ service levels and logistics costs. Recently, their complexity has dramatically increased due to their ever-demanding requirements and pressures from stakeholders and society. In this context, companies have started to search for solutions for greener warehousing processes and energy efficiency improvements. Still, on the academic side, a limited number of studies have been found addressing the quantification of logistics facilities’ environmental performance, the impact of the green warehousing practices in place, and the related effects on warehouse consumption and emission reduction. This paper aims to address this research gap by proposing a simulation-based approach where multiple scenarios of a real logistics facility are discussed, grounded on a conceptual framework that offers a roadmap towards sustainable and energy-efficient warehousing. Different scenarios are outlined, and the related performances are examined in terms of energy consumption and CO2eq emissions. Implications of the results are discussed and streams for future investigation are identified
Assessing the impact of smart lighting systems and on-site renewable generation in a distribution warehouse: a simulation-based approach
Full text linkIn the arena of logistics management, green warehousing has been achieving increasing attention from both practitioners and academia. On the one hand, practitioners – e.g., Logistics Service Providers (LSPs), manufacturers, and retailers – have been looking for solutions to decrease the environmental impact of their logistics facilities and incorporate measures towards greener warehousing processes. However, on the academic side, although a rising number of papers have been found addressing logistics sustainability, a need has emerged to focus on warehouses by analyzing the impact of the energy efficiency measures in place, and the related effects on warehouse consumption and environmental performance. This contribution aims at addressing this research gap. The paper proposes a simulation model based on DesignBuilder and EnergyPlus software and examines the impact of both interventions on the lighting systems and the introduction of on-site renewable generation in a distribution warehouse. Three different scenarios are proposed, and the related performance are examined in terms of consumption figures and CO2eq emissions. A discussion on the roadmap towards net-zero logistics facilities is offered, and streams for future investigation are highlighted
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
