35 years of grey system theory in economics and education

Abstract

PurposeThe Grey System Theory (GST) is an emerging area of research within artificial intelligence. Since its founding in 1982, it has seen a lot of multidisciplinary applications. In just a short period, it has garnered some considerable strengths. Based on the 1987–2021 data collected from the Web of Science (WoS), the current study reports the advancement of the GST.Design/methodology/approachResearch papers utilizing the GST in the fields of economics and education were retrieved from the Web of Science (WoS) platform using a set of predetermined keywords. In the final stage of the process, the papers that underwent analysis were manually chosen, with selection criteria based on the information presented in the titles and abstracts.FindingsThe study identifies prominent authors, institutions, publications and journals closely associated with the subject. In terms of authors, two major clusters are identified around Liu SF and Wang ZX, while the institution with the highest number of publications is Nanjing University of Aeronautics and Astronautics. Moreover, significant keywords, trends and research directions have been extracted and analyzed. Additionally, the study highlights the regions where the theory holds substantial influence.Research limitations/implicationsThe study is subject to certain limitations stemming from factors such as the language employed in the chosen literature, the papers included within the Web of Science (WoS) database, the designation of works categorized as “articles” in the database, the specific selection of keywords and keyword combinations, and the meticulous manual process employed for paper selection. While the manual selection process itself is not inherently limiting, it demands a greater investment of time and meticulous attention, contributing to the overall limitations of the study.Practical implicationsThe significance of the study extends not only to scholars and practitioners but also to readers who observe the development of emerging scientific disciplines.Originality/valueThe analysis of trends revealed a growing emphasis on the application of GST in diverse domains, including supply chain management, manufacturing and economic development. Notably, the emergence of COVID-19 as a new research focal point among GST scholars is evident. The heightened interest in COVID-19 can be attributed to its global impact across various academic disciplines. However, it is improbable that this interest will persist in the long term, as the pandemic is gradually brought under control.

Mapping the Research Landscape of Industry 5.0 from a Machine Learning and Big Data Analytics Perspective: A Bibliometric Approach

“…Table 10 includes the most global cited documents on Industry 5.0, ML, and big data analytics, the number of authors, region, total citations, total citations per year, and normalized total citations (NTC). NTC refers to citations to all authors of the paper, assuming an equal effort from all authors while taking into account the average citations per document for each paper published in the same year [59][60][61]. Extracting the main information from all ten papers, we can see the focus of each author, how the articles evolved, and what the main topics are.…”

Theoretical Framework and Research Proposal for Energy Utilization, Conservation, Production, and Intelligent Systems in Tropical Island Zero-Carbon Building

“…In the mid-20 th century, ecologists Howard T. Odum and Eugene P. Odum introduced system theory into the field of ecology, pioneering research in ecosystem ecology, energy ecology, etc., and proposing the ecosystem theory [36]. Fritjof Capra combined systems theory with ecology, physics, and philosophy at the end of the 20th century, proposing the connection between ecology and science [37]. Peter Senge, on the other hand, proposed a theory of organizational learning in the fields of organizational science and management, applying system thinking to organizational management [38].…”

Mathematical Patterns in Fuzzy Logic and Artificial Intelligence for Financial Analysis: A Bibliometric Study

“…Bibliometric analysis has gained momentum and is increasingly used in all fields because its main benefit is the complex scientific mapping [21], over a specific time period, highlighting new trends that practitioners or decision-makers in various domains can apply [22,23]. Lately, there has been a growing number of bibliometric studies where authors emphasize the importance of utilizing fuzzy logic in various domains such as marketing [24], big data [25], decision management [26], financial modeling [27], and more [28].…”
