Big Challenges of Small Manufacturing Enterprises in Industry 4.0

Systematic Literature Review Predictive Maintenance Solutions for SMEs from the Last Decade

“…In addition to the manager expectations and concerns mentioned above, which were repeated in numerous articles, highlighting their relevance, there are other expectations from the organization's stakeholders. Dobrotvorskiy et al [24] noted that a graphical user interface maintenance management system is really critical for decision-making for users who are not skilled in IT. Regarding the subject of a user-friendly environment for a computerized maintenance management system (CMMS), Campos et al [25] attempted to find a new way to dynamically interact with the physical environment, that is, the workplace, and support information systems, leading to faster responses to events and increased performance.…”

“…Figure 7 shows examples of each the above groups. Other challenges discussed in the recent research, specifically on the subject of predictive maintenance, include investments and unclearly defined costs (based on a questionnaire in 2019 on Industry 4.0 regarding Serbian SMEs) [34], not enough opportunities for failure and small-sample learning tasks [17,35], a lack of highly qualified users [24], Other challenges discussed in the recent research, specifically on the subject of predictive maintenance, include investments and unclearly defined costs (based on a questionnaire in 2019 on Industry 4.0 regarding Serbian SMEs) [34], not enough opportunities for failure and small-sample learning tasks [17,35], a lack of highly qualified users [24], and the loss of specialists or the dependence of the system on them [36], forcing organizations to absorb increasingly more distant knowledge faster and with fewer opportunities for reuse [37]. This modeling and integration of large volumes of industrial data [38] are in contrast to small sample prediction problems [26].…”

Selection of worm gearing optimal structure for machine rotary table

“…Design and modernization of the structure of the rotary tables with drive worm gears in various computer-aided design systems are carried out [4]. Given the specifics of the products under consideration, the availability of regulatory design documentation is promising the use of CAD/CAM/CAE KOMPAS-3D [5][6][7].…”

“…As [24] rightly claims, one of the research main goals of mechanical transmissions is to create a working 3D model for analyzing contact geometry, visual identification, and evaluating the ratios of many tooth geometric parameters. The composition of the designer's toolkit should include a method for creating a gearwheel three-dimensional model in the corresponding integrated CAD systems [4,6,7].…”

Research of toothed belt transmission with arched teeth

“…In modern computer-aided design (CAD) systems, a parameterization toolkit is implemented to reduce design time and improve the quality of design decisions made [5]. In CAD systems of the "middle" and "heavy" class, the presence of a parametric model is embedded in the functioning mechanism of CAD systems.…”
