However, it would be more appropriate to apply a fuzzy integral model, in which it is not necessary to assume additivity and independency, to approximate the human subjective evaluation process. This research modifies an effective algorithm to determine the l-value by the input data of fuzzy densities and by fuzzy integral based on l-fuzzy measure to determine the overall evaluation. Finally, this research gives an example of enterprise intranet web sites evaluation with illustrations of hierarchical structure of l-fuzzy measure for Choquet integral model, and the results show fuzzy integral is more suitable than a traditional multi-criteria evaluation method for human subjective evaluation or criteria are not mutually independent.
