Ergonomic Factors Impacting Industrial Operator Performance, Productivity, and Musculoskeletal Health

This paper investigates the intricate relationship between workplace factors and their influence on the occurrence of Work-Related Musculoskeletal Disorders (WMSDs). It delves into the factors affecting industry operators' performance, emphasizing the role of organizational, ergonomic, and individual factors as triggering elements. To quantitatively assess these factors' contributions to a person's work productivity, a novel grid model is proposed, enabling a structured evaluation. The study involved a cohort of ten actively participated in the study. Participants provided insights into workplace conditions significantly affecting WMSDs through a meticulously designed questionnaire. The mathematical model presented here adopts a systematic and analytical approach, employing algebraic equations to represent both hyperbolic and linear relations. This model establishes a structured framework for the assessment and optimization of workplace conditions, ultimately aiming to reduce the incidence of WMSDs. Parametric studies were conducted to evaluate the model's effectiveness, facilitating the prediction of different factors' impacts on the performance index linked to WMSD reduction. Results indicate that ergonomic factors affected 60% of the participants’ performance. Similarly, individual factors affected 20% and organisational factors affected 50% of the participant's performance. This paper sheds light on the dynamic interplay of these factors, offering valuable insights for the prevention of WMSDs in various occupational settings.
