Abstract:

The scale model for judgment linguistic can directly affect the scientific and rationality of integration calculation results in complex system decision-making. The principle of outside objective stimuli and psychological subjective judgment is analyzed from the perspective of psychophysics. The psychophysics model between the numerical system of the scale model and the judgment linguistic set of paired comparison is established. Two scale models for judgment linguistic of paired comparison are constructed based on Weber-Fechner (W-F) law and Stevens’ power law, and the detailed numerical system of the two scale models is calculated. The advantages of the scale model based on psychophysics are verified from its application results and own characteristics,with using the standard uniform judgment matric as the verify instance. And the results of the verify instance show that the W-F law is more appropriate than the Stevens’ power law on the research for the complex system decisionmaking.
