Given the importance of human centricity, resilience, and sustainability, the emerging concept of Industry 5.0 has pushed forward the research frontier of the technology-focused Industry 4.0 to a smart and harmonious socio-economic transition driven by both humans and technologies, where the role of the human in the technological transformation is predominantly focused on. Several studies discuss the impacts of disruptive technologies on smart logistics operations in Industry 4.0. However, since Industry 5.0 is a new concept and still in its infancy, its implications for smart logistics have not been discussed. To fill this gap, this paper presents a comparative bibliometric analysis to show the connection and differences between Industry 4.0 and Industry 5.0 and their implications for smart logistics. A thorough content analysis is then given to illustrate the features of smart logistics in Industry 5.0 concerning four areas, namely intelligent automation, intelligent devices, intelligent systems, and intelligent materials. The results show that, compared with Industry 4.0, the research of smart logistics in Industry 5.0 puts more focus on the interaction between humans and technology in the digital transition, with the increasing adoption of collaborative technologies, e.g., human–machine systems, collaborative robots, and human–robot collaboration. Finally, a research agenda is proposed for identifying future research directions of smart logistics in Industry 5.0.
It is inevitable that technological improvements have affected human's life in any aspect to a large extent. Automation, artificial intelligence, robotics, etc., are some advances contributed to the fourth industrial revolution: Industry 4.0. Despite there are still many arguments, Internet of Things (IoT) and Cyber Physical Systems (CPS) have been widely acknowledged as the main fundaments of Industry 4.0. This paper introduces the concept of CPS by providing an explicit framework that unifies the existing theories in this regard. Nine exquisite technologies attributed to Industry 4.0 are investigated, among which virtual technology (VT) and digital twin (DT) are considered as two of the core criteria and are thus focused on in this paper. However, for providing an acceptable level of integration and intelligence, noticeable gap between the virtual world and the real factory is still a significant challenge. Holistic approaches addressing this issue suggest VTs and DT have the potential to form the fundaments for more improvements in terms of both interoperability and consciousness. Furthermore, they may pave the way for achieving the highest level of CPS and Industry 4.0.
The broad and extensive application of public-private partnership (PPP), as well as the divergent documented definitions and experiences, have led to a translucent perspective of PPP and strained academia and industry to reach a consensus on the major practice of this concept. Early contractor involvement (ECI), governance tools, and relational contracting are only a few of the frameworks attributed to PPP. This issue has received limited attention from researchers, despite the focus of review studies on different disciplines of PPP. Hence, this paper puts forward the idea of conducting a comprehensive review to not only shed light on the major practice of PPP but also provide a wider outlook on this concept based on the research carried out since 1979. A narrative review is initially accomplished to identify the major drivers and milestones that have contributed to the evolution of PPP. Employing bibliometric analysis in the following phase assists in conducting a multi-dimensional assessment of studies published within the last five decades. The economic and societal practices of PPP throughout its evolution path signified the dominant application of this concept as a business model. The bibliometric analysis revealed that PPP has contributed to various sectors, i.e., urban development, public infrastructure, transportation, health, and education, just to name a few. In addition, economic and organizational management of PPP was revealed as a major research stream that was accompanied by sustainable development. As a matter of fact, economic and environmental sustainability are the major cross-disciplinary elements that form an interplay between the drivers and attributes of PPP. Value for money (VfM), technology, and innovation, along with smart infrastructure (SI) and smart cities (SCs), are identified as the major directions for the future research agenda associated with PPP.
