An Adaptive Model of the Fuzzy Variable - Quality Index

In this article we discuss a model of quality as the fuzzy variable in order to better understand the concept and thus enable the further development of the variable. We propose a general method to estimate the quality index which can handle both qualitative and quantitative factors. The method uses a fuzzy neural network since the system learns how to integrate the human judgment of quality into a quantitative index. In our case study we have examined the measurement of image quality and pulp quality.
