In this paper, we address the most pressing challenges faced by the manufacturing sector, particularly the manufacturing of small and medium-sized enterprises (SMEs), where the transition towards high-mix low-volume production and the availability of cost-effective solutions are crucial. To overcome these challenges, this paper presents 14 innovative solutions that can be utilized to support the introduction of agile manufacturing processes in SMEs. These solutions encompass a wide range of key technologies, including reconfigurable fixtures, low-cost automation for printed circuit board (PCB) assembly, computer-vision-based control, wireless sensor networks (WSNs) simulations, predictive maintenance based on Internet of Things (IoT), virtualization for operator training, intuitive robot programming using virtual reality (VR), autonomous trajectory generation, programming by demonstration for force-based tasks, on-line task allocation in human–robot collaboration (HRC), projector-based graphical user interface (GUI) for HRC, human safety in collaborative work cells, and integration of automated ground vehicles for intralogistics. All of these solutions were designed with the purpose of increasing agility in the manufacturing sector. They are designed to enable flexible and modular manufacturing systems that are easy to integrate and use while remaining cost-effective for SMEs. As such, they have a high potential to be implemented in the manufacturing industry. They can be used as standalone modules or combined to solve a more complicated task, and contribute to enhancing the agility, efficiency, and competitiveness of manufacturing companies. With their application tested in industrially relevant environments, the proposed solutions strive to ensure practical implementation and real-world impact. While this paper presents these solutions and gives an overview of their methodologies and evaluations, it does not go into their details. It provides summaries of comprehensive and multifaceted solutions to tackle the evolving needs and demands of the manufacturing sector, empowering SMEs to thrive in a dynamic and competitive market landscape.

“…Total hours worked and the numbers of injury sustained during the hours as reported by each subject are stated. Column 4 and 5 are the accidents rating and meanings respectively for each of the workplaces derived by using EME aforementioned in equation (1). Column 6 and 7 reported the accident rating predictions of the developed expert system and the interpretations of the output using Table 3 respectively.…”

“…Many studies were reported by other authors on analysing and improving ergonomics of workstation. The major focus of all the researches were to improve operator's performance and comfort on the assigned tasks [1][2][3]. Washington State Department of Labor and Industries [4] suggested that while employees in micro sized work places are allowed to set up their own workstation to suit the way they work, managers in those of small-to-medium sized company should evaluate all of their office jobs stations to comprehensively ensure implementation of ergonomics program to reduce accident.…”

In this study, a fuzzy-based expert system called Accident Prone Workstations Prediction Expert System (APWAPES) was developed to forecast unsafe level of work stations. APWAPES used fuzzy set theory to make decisions based on the “Total-hours-worked” and “Injury-Count” as inputs and “Workstation-unsafe-ratings” as the output. Data collected from subjects in 20 workstations were run with APWAPES. The results were compared with an Existing Mathematical Model (EME). The validation result showed that there was a strong positive relationship between the EME and the developed APWAPES with a correlation coefficient of 0.710. The t-test result for mean difference showed that EME had a statistically significantly higher level of rating (0.60 ± 0.30, SEM=0.004) compared to APWAPES (0.50 ± 0.02, SEM= 0.007), t(38) = 1.613, p = 0.115. With a significance level of 0.001 at 95% confidence, the APWAPES and the EME predicted values were not significantly different. The study developed an expert system, APWAPES, which can find its applications in any work place where hazards occur and capable of helping managers of industries, to measure work places and/or activities disposed to accidents.

“…Neglect of ergonomic principles brings inefficiency and pain to the workforce. An ergonomically deficient workplace can cause physical and emotional stress, low productivity and poor quality of work (Ayoub, 1990a(Ayoub, , 1990b [8] A workstation should be designed such that it minimizes the working area, so that while carrying out the operations, the worker can use shorter motions and expend less energy, thus reducing fatigue [6]. Das and Grady [7]reviewed the concept of workspace design and the applications of anthropometric data.…”

Ergonomics is the science and technology of fitting the activities and environment to the abilities, dimensions, and needs of people to improve performance while enhancing comfort, health and safety [1] The objective of the present study was to investigate the effects of an ergonomically designed adjustable workstation for performing a repetitive industrial assembly task on operator performance and productivity. Ergonomically designed fully adjustable assembly workstations could be expensive for companies to adopt, especially the small scale industries. Therefore, a low-cost, ergonomically designed adjustable assembly workstation was designed, developed and evaluated for assembly of a product in a manufacturing company. Experiments were conducted on the existing fixed height and on the newly designed ergonomic assembly workstation using five industrial assembly operators. The operator performance on the ergonomically designed workstation was 29% higher compared to the existing non ergonomically designed fixed height assembly workstation. The increased performance was due to flexibility and ergonomic design features incorporated in the workstation.
