Unveiling the relationship between sustainable development and Industry 4.0: A text mining literature analysis

Abstract

This article aims to assess the evolution of the literature on the link between Industry 4.0 and sustainable development. Through a systematic analysis of the literature, a sample of 234 documents was identified, published between 2011 and 2021. Given the large number of papers collected, the text mining approach was performed to analyze the sample of documents. In particular, the latent Dirichlet allocation model was adopted to group articles in different relevant topics starting from two dictionaries belonging to terms both in the domain of Industry 4.0 and in sustainability. As a result, 11 different topics have been identified that link these two domains. The results showed a strong predominance of Industry 4.0 compared to sustainability models that are very focused only on the environmental aspect. In conclusion, this study emphasizes future research potential by highlighting these existing research areas.

A Quality Control Improvement Model That Takes into Account the Sustainability Concept and KPIs

“…These opposing approaches are often considered in terms of environmental protection, but the idea of sustainable development goes beyond this [39]. It is about fusing and balancing different planes, which include the following: the natural-economic plane, the technical plane, the economic plane, the social plane and the political plane [40].…”

Project management for sustainable development: Critical determinants of technological competency for project managers with smart technologies

“…In the context of pronounced natural resource scarcity and significant environmental issues, the Environmental, Social and Governance (ESG) and the Sustainable Development Goals (SDGs) have been proposed, becoming the focal points of interest across various industries (Hák et al, 2016;Mhlanga, 2022;Strazzullo et al, 2023;Teixeira Dias et al, 2023). ESG may positively or negatively impact the financial performance or solvency of companies and even industries (Li et al, 2021;Teixeira Dias et al, 2023).…”

Data science approaches for sustainable development

“…In fact, at the moment, the empirical evidence regarding the advantages provided by data science to sustainability is reduced. However, there are numerous cases of implementation of data science applications aimed at fostering a transition towards an economy based on reuse and recovery and reducing the consumption of resources, and, above all, polluting emissions (Dantas et al, 2021;de Miranda et al, 2021;Strazzullo et al, 2023).…”
