To promote the healthy and stable development of infant dairy industry, this work starts from the background of family planning policy adjustment. Based on the Internet of Things (IoT), fertility policy, and other related theories, this work analyzes the population size changes and fertility willingness of Chinese women of childbearing age between 20 and 39 years old from 1980 to 2020. Additionally, this work discusses the current development of infant dairy industry and the willingness of residents in the first, second, third, and fourth tier cities to purchase domestic or imported milk powder. Finally, the IoT technology is introduced into the farm and infant dairy processing links for analysis. The results show that the population of women of childbearing age in China is shrinking year by year, and the willingness to bear children is also declining. From 2016 to 2021, the number of women of childbearing age will decrease by an average of 2.85 million every year. Women in rural areas are more willing to give birth than those in urban areas. Compared with Vietnam and India, China has the lowest population growth rate, followed by Vietnam and India. At present, the development of domestic infant dairy products is facing many setbacks due to the reduction of the birth population, the impact of foreign brands, and the “melamine” incident. Fortunately, due to the strict supervision of the market by the government, a certain proportion of the market has been gradually achieved in recent years. However, residents of the first, second, third, and fourth tier cities are still more willing to buy foreign milk powder. Introducing the IoT technology into the development of infant dairy industry can monitor the content of relevant additives and record the production information through radio frequency identification technology, which improves the quality of dairy products to a certain extent. Therefore, the research on the management of infant dairy industry integrated with the IoT under the background of family planning policy adjustment will have a certain beneficial impact on the subsequent development of the industry.

“…In this section, we detail an exploratory user study, which is the third iteration round of a project that investigates the application of VR for technical documentation creation purposes. The previous iterations were focused on the early phases of documentation creation [46][47][48], while in this work, we demonstrate how VR can be used for collaborative technical documentation reviews and risk assessments. The focus of this study is not on the development of a VR platform but evaluating the usefulness and benefits of VR for the case study.…”

“…The VR platform used in the user study, COVE-VR, was designed based on the input of subject matter experts and evaluated in collaboration between industrial and academic researchers [46] in several iterations and scenarios [46][47][48]. The following two virtual environments (Lab and Showroom) were deployed to facilitate a wide scope of industrial tasks: (1) a small-sized Lab replicates the realistic context of an elevator shaft based on a 3D CAD model and (2) a Showroom is a larger space to facilitate collaboration of multiple multidisciplinary teams and in-depth investigation of 3D CAD models that would not be possible to perform in a smaller space.…”

Technical documentation creation is a collaborative process involving several departments in R&D. Even though virtual reality (VR) has been demonstrated to facilitate industrial collaboration and advance the product development lifecycle in earlier studies, it has not been utilized for technical documentation review and risk assessment processes in industrial companies. This article presents a case study where the benefits of VR to maintenance documentation reviews and risk assessments were studied. The virtual reality environment was tested by nine domain experts from an industrial company in a user study that replicated their actual real-life industrial collaboration tasks. Both qualitative and quantitative data were collected during the study. Our findings show that collaborative VR has the potential to enhance the documentation review and risk assessment processes. Overall, the concept of using virtual reality for documentation review and risk assessment processes was rated positively by participants, and even though further development is needed for the review tools, VR was viewed as a concept that facilitates collaboration, enhances the current review practices, and increases spatial understanding. The benefits of VR are evident, especially for geographically scattered teams that rarely meet face-to-face or do not have access to the actual physical equipment. In cases where traditional means of communication are not enough, process improvements are needed for documentation review and risk assessment processes, and our proposed solution is VR.

Maintenance Performance in the Age of Industry 4.0: A Bibliometric Performance Analysis and a Systematic Literature Review

Recently, there has been a growing interest in issues related to maintenance performance management, which is confirmed by a significant number of publications and reports devoted to these problems. However, theoretical and application studies indicate a lack of research on the systematic literature reviews and surveys of studies that would focus on the evolution of Industry 4.0 technologies used in the maintenance area in a cross-sectional manner. Therefore, the paper reviews the existing literature to present an up-to-date and content-relevant analysis in this field. The proposed methodology includes bibliometric performance analysis and a review of the systematic literature. First, the general bibliometric analysis was conducted based on the literature in Scopus and Web of Science databases. Later, the systematic search was performed using the Primo multi-search tool following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The main inclusion criteria included the publication dates (studies published from 2012–2022), studies published in English, and studies found in the selected databases. In addition, the authors focused on research work within the scope of the Maintenance 4.0 study. Therefore, papers within the following research fields were selected: (a) augmented reality, (b) virtual reality, (c) system architecture, (d) data-driven decision, (e) Operator 4.0, and (f) cybersecurity. This resulted in the selection of the 214 most relevant papers in the investigated area. Finally, the selected articles in this review were categorized into five groups: (1) Data-driven decision-making in Maintenance 4.0, (2) Operator 4.0, (3) Virtual and Augmented reality in maintenance, 4) Maintenance system architecture, and 5) Cybersecurity in maintenance. The obtained results have led the authors to specify the main research problems and trends related to the analyzed area and to identify the main research gaps for future investigation from academic and engineering perspectives.
