A systematic review on multi-criteria group decision-making methods based on weights: analysis and classification scheme

Interest in group decision-making (GDM) has been increasing prominently over the last decade. Access to global databases, sophisticated sensors which can obtain multiple inputs or complex problems requiring opinions from several experts have driven interest in data aggregation. Consequently, the field has been widely studied from several viewpoints and multiple approaches have been proposed. Nevertheless, there is a lack of general framework. Moreover, this problem is exacerbated in the case of experts’ weighting methods, one of the most widely-used techniques to deal with multiple source aggregation. This lack of general classification scheme, or a guide to assist expert knowledge, leads to ambiguity or misreading for readers, who may be overwhelmed by the large amount of unclassified information currently available. To invert this situation, a general GDM framework is presented which divides and classifies all data aggregation techniques, focusing on and expanding the classification of experts’ weighting methods in terms of analysis type by carrying out an in-depth literature review. Results are not only classified but analysed and discussed regarding multiple characteristics, such as MCDMs in which they are applied, type of data used, ideal solutions considered or when they are applied. Furthermore, general requirements supplement this analysis such as initial influence, or component division considerations. As a result, this paper provides not only a general classification scheme and a detailed analysis of experts’ weighting methods but also a road map for researchers working on GDM topics or a guide for experts who use these methods. Furthermore, six significant contributions for future research pathways are provided in the conclusions.The first author acknowledges support from the Spanish Ministry of Universities [grant number FPU18/01471].

Multi-criteria site selection workflow for geological storage of hydrogen in depleted gas fields: A case for the UK

Underground hydrogen storage (UHS) plays a critical role in ensuring the stability and security of the future clean energy supply. However, the efficiency and reliability of UHS technology depend heavily on the careful and criteria-driven selection of suitable storage sites. This study presents a hybrid multi-criteria decision-making framework integrating the Analytical Hierarchy Process (AHP) and Preference Ranking Organisation Method for Enrichment of Evaluations (PROMETHEE) to identify and select the best hydrogen storage sites among depleted gas reservoirs in the UK. To achieve this, a new set of site selection criteria is proposed in light of the technical and economic aspects of UHS, including location, reservoir rock quality and tectonic characteristics, maximum achievable hydrogen well deliverability rate, working gas capacity, cushion gas volume requirement, distance to future potential hydrogen clusters, and access to intermittent renewable energy sources (RESs). The framework is implemented to rank 71 reservoirs based on their potential and suitability for UHS. Firstly, the reservoirs are thoroughly evaluated for each proposed criterion and then the AHP-PROMETHEE technique is employed to prioritise the criteria and rank the storage sites. The study reveals that the total calculated working gas capacity based on single-well plateau withdrawal rates is around 881 TWh across all evaluated reservoirs. The maximum well deliverability rates for hydrogen withdrawal are found to vary considerably among the sites; however, 22 % are estimated to have deliverability rates exceeding 100 sm3/d, and 63 % are located within a distance of 100 km from a major hydrogen cluster. Moreover, 70 % have access to nearby RESs developments, with an estimated cumulative RESs capacity of approximately 181 GW. The results highlight the efficacy of the proposed multi-criteria site selection framework. The top five highest-ranked sites for UHS based on the evaluated criteria are the Cygnus, Hamilton, Saltfleetby, Corvette, and Hatfield Moors gas fields. The insights provided by this study can contribute to informed decision-making, sustainable development, and the overall progress of future UHS projects within the UK and globally

Silent Light, Luminous Noise: Photophonics, Machines and the Senses

This research takes the basic physical premise that sound can be synthesized using light, explores how this has historically been, and still is achieved, and how it can still be a fertile area for creative, theoretical and critical exploration in sound and the arts. Through the author's own artistic practice, different techniques of generating sound using the sonification of light are explored, and these techniques are then contextualised by their historical and theoretical setting in the time-based arts. Specifically, this text draws together diverse strands of scholarship on experimental sound and film practices, cultural histories, the senses, media theory and engineering to address effects and outcomes specific to photophonic sound and its relation to the moving image, and the sculptural and media works devised to produce it. The sonifier, or device engendering the transformations discussed is specifically addressed in its many forms, and a model proposed, whereby these devices and systems are an integral, readably inscribed component - both materially and culturally - in both the works they produce, and via our reflexive understanding of the processes involved, of the images or light signals used to produce them. Other practitioners' works are critically engaged to demonstrate how a sense of touch, or the haptic, can be thought of as an emergent property of moving image works which readably and structurally make use of photophonic sound (including the author's), and sound's essential role in this is examined. In developing, through an integration of theory and practice, a new approach in this under-researched field of sound studies, the author hopes to show how photophonic sound can act as both a metaphorical and material interface between experimental sound and image, and hopefully point the way towards a more comprehensive study of both

Peopled Landscapes (Terra Australis 34)

This impressive collection celebrates the work of Peter Kershaw, a key figure in the field of Australian palaeoenvironmental reconstruction. Over almost half a century his research helped reconceptualize ecology in Australia, creating a detailed understanding of environmental change in the Late Pleistocene and Holocene. Within a biogeographic framework one of his exceptional contributions was to explore the ways that Aboriginal people may have modified the landscape through the effects of anthropogenic burning. These ideas have had significant impacts on thinking within the fields of geomorphology, biogeography, archaeology, anthropology and history. Papers presented here continue to explore the dynamism of landscape change in Australia and the contribution of humans to those transformations. The volume is structured in two sections. The first examines evidence for human engagement with landscape, focusing on Australia and Papua New Guinea but also dealing with the human/environmental histories of Europe and Asia. The second section contains papers that examine palaeoecology and present some of the latest research into environmental change in Australia and New Zealand. Individually these papers, written by many of Australia’s prominent researchers in these fields, are significant contributions to our knowledge of Quaternary landscapes and human land use. But Peopled Landscapes also signifies the disciplinary entanglement that is archaeological and biogeographic research in this region, with archaeologists and environmental scientists contributing to both studies of human land use and palaeoecology. Peopled Landscapes reveals the interdisciplinary richness of Quaternary research in the Australasian region as well as the complexity and richness of the entangled environmental and human pasts of these lands
