Investigation of the Collaboration Net-work of the Faculty Members of the Technical and Engineering Research Institute of the Ministry of Science, Re-search and Technology in Tehran: 2011-2015

The purpose of this research is to analyze the collaboration of faculty members in the field of engineering in research Institutes in Iranian Ministry of Science, Research and Technology in Tehran during 2011-2015.

The research method is scientometrics and social network analysis. The population is scientific production of 7 institutes, which are extracted from databases.

the researchers with high scientific production were identified. There are also more scientific productions with more than 3 authors. Nearly %26 of researchers have collaborated with each other. Based on the SNA indicators, NIGB is the most active institute in the formation of scientific networks of research and technical areas.

Subject field can be one of the factors of high scientific production for IIPPI and NIGEG. The result showed that in scientific interactions, the trend of group work in TETRI is weak. One of the reasons might be paying attention to the basic topics of each discipline and lack of attention to the solution of interdisciplinary issues. The NIGEG has a privileged position among other research institutes and has more power and influence in the network. The United States has been the focus of the researchers' attention, and this could be due to fewer obstacles in the country.
