“…It makes an important contribution to the design and assessment of tasks, jobs, products, work environments, and organizational systems so that they meet employees' needs, capabilities, and limitations (IEA, 2023). Er-gonomics is also the science of adapting workplaces, machines, and devices to humans to ensure safety and optimal efficiency so as not to force employees to adapt to non-ergonomic workstations and tasks, which may hurt their health and workplace well-being (Lasota & Hankiewicz, 2017b). Therefore, machines, tools, workplaces, and work environments must be best adapted to human capabilities and limitations.…”

In the era of Industry 4.0, digital human modeling (DHM) may be the key to improving ergonomics related to manual operations in the workplace. Poor workplace ergonomics may lead to reduced work productivity and an increased risk of health problems among employees, resulting in actual losses for enterprises, e.g., sickness absence, employee turnover, and training. DHM technology can help speed up ergonomic analysis and improvement. This paper proposes a methodological framework based on DHM to improve ergonomics in the workplace. Its purpose is to provide practitioners with an easy and detailed approach to ergonomics assessment and improvement procedures. The framework developed two main stages: the workplace Research Stage and the DHM and Simulation Stage, which cover the eight detailed steps of an effective DHM-based ergonomic assessment together. A case study was used to verify and demonstrate the effectiveness of the proposed methodological framework.

“…On the other hand, in South America, the First National Survey of Employment, Work, Health and Quality of Life Conditions was carried out in the country of Chile, which showed that 2 out of 10 working people suffer from MSDs [4]. A study carried out in Poland shows that there are characteristic postures in the production of upholstery and repetitive movements that affect the spine, arm movements below the shoulder joint and constant rotation of the body with large parts, which has repercussions on health problems, absenteeism, and low quality of work [5].…”

The present research work has the purpose of simulating an ergonomic improvement in the furniture production workshop for the areas that show a higher risk of musculoskeletal disorders. In this sense, ergonomics methods and instruments such as the Nordic questionnaire were used to measure the body areas, due to the increase in cases of MSDs related to physical work in the upholstery sector. These disorders develop due to the lack of an adequate ergonomic design and the lack of early identification that prioritizes the well-being of workers. Thus, NIOSH, RULA and OWAS methodologies were applied to evaluate the level of risk and lifting index before and after. These values were contrasted with Ergosoft Pro and 3DSSPP software to validate the design proposal. Thus, the risk level was reduced from a value of 4 to 1 and the uplift index from 3.8 to 0.99. In addition, artificial intelligence was employed through the application of Open Pose to achieve the estimation of the arm angles in real time.

“…Researchers widely use risk assessment methods to evaluate jobs, health outcomes and risk to WRMSDs of occupational groups in the production and assembly systems [8,9,11,27,34,35]. However, many industrial jobs are multi-task in nature [36] and there are multipurpose workstations.…”

The profile of human factors and ergonomics is rising. To provide an ergonomic work environment, it is necessary to pay special attention to the design and evaluation of the workplace. Traditional production work practices do not sufficiently take into account task variability in job design and assessment. Variations in task content, organizational work performance are seen due to the effective use of equipment, which enables higher levels of productivity to be reached. However, this variation has an impact on physical ergonomics risk factors and, consequently, on the risk of developing work-related musculoskeletal disorders. Variations can cause difficulties in assessing workers' exposure to ergonomic risk. This study aims to develop a framework for the evaluation of physical ergonomic risk in multipurpose workplaces. The presented framework integrates the concepts of well-known observation techniques used in the assessment of physical ergonomic risk factors in the multipurpose workplace. The research framework highlights a worker's exposure to the ergonomic risk and illustrates how these results can be used to find solutions in future ergonomic interventions. The framework's application is presented by illustrative case studies. Theoretical, managerial and practical features of the framework are discussed.
