Abstract: Based on the concept of pan-integral defined in fuzzy measure space, the concept of fuzzy evaluation pan-space is given as a derivative. Discussing the common evaluation models and the structure of fuzzy integral, we point out the association between fuzzy synthetic evaluation and pan-integral of which the convergence theorem can play well a basic role in association. In view of that the pan-integral is highly abstract and generalizable, it has good prospects for a wide application in fuzzy synthetic evaluation. Two examples are given showing the practicality of applications.
