METHODOLOGICAL FRAMEWORK FOR THE DEVELOPMENT AND MULTICRITERION VALIDATION OF THE EFFECTIVE ERGONOMIC LOAD MODEL

<p>This paper aims to present a methodological framework for the development and validation of the<br />Effective Ergonomic Load Coefficient (KEEO) model, an approach that seeks to quantify total<br />workload by integrating physical, mental, organizational, and technical and technological factors.<br />Current methods, such as RULA, REBA, OCRA, SWAT, and JCQ, address only individual aspects of<br />work and thus limit insight into the entirety of ergonomic risk. KEEO is based on a multi-criteria<br />integration of methodologies for determining weights and factors that have been identified as<br />determinants of ergonomic workload. Validation includes assessment of the content validity of the<br />questionnaire, analytical boundary checking, sensitivity analysis, and Monte Carlo simulation. The<br />results obtained show stable linear behavior and proportionality between components, suggesting<br />that KEEO can serve as a basis for future integrated ergonomic workload indices. This<br />methodological work is the result of work on a doctoral dissertation on the topic "Multi-functional<br />analysis of effective workplace workload".</p>
