Abstract :In this study, we evaluate the effect of demographic factors such as age, gender, marital status, and education level on mental workload of TEYDEB’s insert ignore into journalissuearticles values(Technology & Innovation Grant Programs Directorate); experts working in basic stages of R&D projects evaluation activities. One of the workload measurement techniques, NASA-TLX is chosen since it is the most convenient measurement technique for the experiment groups used in this study. We make statistical analyses to measure the effectiveness of 6 scales used in NASA-TLX for evaluating the subjective mental workload of TEYDEB’s experts. In the second phase of the study, output of NASA-TLX is used by AHP insert ignore into journalissuearticles values(Analytic Hierarchy Process); and TOPSIS insert ignore into journalissuearticles values(Technique for Order Preference by Similarity to Ideal Solutions); methods to construct an expert system for choosing an executive expert from TEYDEB’s expert pool.
Keywords : Mental workload, NASA TLX, AHP, TOPSIS
