Today all countries are attempting to increase their investments in research. In this order, industrial and developed countries to preserve their current position, or to advance themselves on the scene of global competition, in research investments, while developing countries have understood that for fundamental solution to their social and economic problems and real development, they have no other choice of increasing their research investments. In Iran, attention to research has noticeably extended in recent decade. Development of graduate studies in universities especially in PhD level led to the rapid rise and dramatic science production in the fields of basic and applied science. Development of technologies which are necessary for converting science to production, can’t be achieved by research activities in graduate level in universities. Thus, main aims of research centers established in universities are for practical and professional research for developing technologies. A regular and continuous performance evaluation for these research centers is needed for considering their aims with useful and effective indexes. In this article, a new model is designed for performance evaluation of research centers, and as a case study the model is used for the performance evaluation of some research centers in Amirkabir University of Technology. One of It ‘s results can determine research centers activities orientation and university uses for more support of research centers that are active more than others. . Some of research centers are weak in performance rank,is studied and university must take necessary action for solving of their problems.
