This study supplies contributions to the existing literature with a state-of-the-art bibliometric review of sustainable industrial and operation engineering as the field moves toward Industry 4.0, and guidance for future studies and practical achievements. Although industrial and operation engineering is being promoted forward to sustainability, the systematization of the knowledge that forms firms’ manufacturing and operations and encompasses their wide concepts and abundant complementary elements is still absent. This study aims to analyze contemporary sustainable industrial and operations engineering in Industry 4.0 context. The bibliometric analysis and fuzzy Delphi method are proposed. Resulting in a total of 30 indicators that are criticized and clustered into eight study groups, including lean manufacturing in Industry 4.0, cyber-physical production system, big data-driven and smart communications, safety and security, artificial intelligence for sustainability, the circular economy in a digital environment, business intelligence and virtual reality, and environmental sustainability. Graphical Abstract

Sustainable corporate finance is an attractive field of study in sustainability literature; however, the literature lacks systematic bibliometric analysis that provides a comprehensive review to clarify state-of-the-art sustainable corporate finance and that discusses new opportunities and potential instructions for further studies. To address this gap, this study adopts a literature review, bibliometric analysis, network analysis and co-wording technique to systematically investigate the Scopus database. In total, 30 keywords listed at least three times are used and are divided into six clusters considering six fields of research, namely, corporate finance in corporate sustainability, sustainable competitive advantages, sustainable stakeholder engagement, circular economy, sustainable corporate finance innovation and risk management and sustainable supply chain ethics. This study contributes to examining the sustainable corporate finance bibliometric status to provide directions for future studies and practical accomplishment. The sustainable corporate finance knowledge gaps are (1) corporate finance in sustainability; (2) sustainable competitive advantages; (3) sustainable stakeholder engagement; (4) circular economy; (5) sustainable corporate finance innovation and risk management; and (6) sustainable supply chain ethics. The knowledge gaps and future directions are also discussed.

Social media has changed how tourists source and assess information about tourist products and destinations. Tourists can now easily share their travel experiences through text-based posts, photographs, and real-time videos on social media. Such word of mouth (WOM) allows tourists to focus on and develop an interest in diverse tourism experiences and efficiently interact with other travelers as reliable information sources. However, studies on the cruise industry remains scarce in this issue. Thus, this study examines the impact of travel information sourced from social media on consumers’ purchase intentions with WOM (WOM praise and WOM activities) as a mediating factor. The analysis employs a value-based adoption model derived from prospect theory and mental accounting theory from the perspective of benefit maximization (information reliability and enjoyment). Empirical data are collected (n = 305) using a survey. Structural equation modeling reveals that social media users’ WOM significantly influences consumers’ purchase intentions. That is, WOM increases the benefits of sourcing information on cruise travels from social media. Further, experience sharing through WOM significantly impacts consumers’ decision making. The study concludes with theoretical and practical implications.

This study contributes a data-driven of sustainable food supply chain with the comparison between Halal and non-Halal food, and suggestion for future studies and practical fulfillments. Although food supply chain is urged to become sustainable, there is a lack of a systematic data-driven describing the most appropriate indicators to advance both Halal and non-Halal sustainable food supply chain. With an aim of analyzing up-to-date sustainable food supply chain, a combination of content analysis, fuzzy Delphi method, fuzzy decision-making trial and evaluation laboratory is presented. The results show that the most significant indicators for non-Halal sustainable food supply chain are food consumption, food safety, food security, resilience, food waste management. The most crucial indicators of Halal sustainable food supply chain consist of Halal certification, Halal supply chain trust, Islamic values, Halal food safety. A contemporary sustainable food supply chain is presented and future trends, challenges, and opportunities are determined.

This study provides insights into digitalization in sustainable supply chain management by establishing a structural set of attributes with causal interrelationships among them, as well as by reporting empirical findings on successful criteria for footwear supply chain practices in Indonesia. Sustainable supply chain management and digitalization are mutual benefits. However, there are unclear cause and effect interrelationships. This study aims to critically pinpoint digitalization to approach sustainability and is designed to help firms achieve supply chain competitiveness. The fuzzy Delphi method and fuzzy decision-making trial and evaluation laboratory are utilized, due to the fuzziness associated with human decision making and the complexity and uncertainty in the supply chain. Five aspects and seventeen criteria are validated. The findings indicate that four aspects, including digital platform effectiveness, digital communication belonging to the supply chain digitalization perspective, labour conditions, and manufacturing processes, are important to sustainable supply chain management. The top causal criteria, including logistics integration, logistics optimization, delivery speed, proactive action, and real-time inventory, are considered to assist firms in implementing better practices.
