Abstract:

 

The determination of subjective workload (SWL) imposed on an employee plays an important role in designing and evaluating an existing work and work environment. Additionally, it is a hard problem since SWL evaluation is typically a multi-dimensional problem involving several work demands on which employee’s evaluation is usually vague and imprecise. In this study, NASA TLX (National Aeronautics and Space Administration Task Load Index) method used widely in different work types combined with intuitionistic fuzzy set (IFS) theory to determine SWL in an industrial sailing firm. The integrated method is named as Intuitionistic Fuzzy TLX (IF-TLX). IFS theory is a powerful tool to model the uncertainty because of degree of hesitation in human decision system. It is worth pointing out that proposed method also considers work experience effect on SWL evaluation. This improves objectivity of final SWL scores for the whole work. This paper also develops a new intuitionistic evaluation scale for rating of SWL dimensions and work experience. As a result of this study it is determined that industrial salespeople who have more than 15 years of work experience feel the highest SWL with the effect of increasing age.
