This paper proposes a neuro fuzzy model for analyzing the relationship between contractor’s qualifications and project quality in research projects. The proposed model has been implemented in a research-based organization, IIES. Cross validation method has been used in order to generate some set of data which have been used for different evaluations. The proposed neuro fuzzy model has dominated the linear regression model not only in average, but also in each data set. Moreover, the results showed a confident relationship between project quality and three criteria used for evaluating the contractor’s qualifications.
