problem statement:
The necessity of regeneration in worn out fabrics, which is the range that is less effective than other peripheral fabrics, is obvious and clear, and one of the policies in this field is the definition of catalyst projects. In summary, catalyst projects are one of the most recent approaches to urban regeneration literature in Iran and in the world, and with their proper location, the fabric of the area in which these projects are located are revived and developed.

The objectives of this study are to determine the location indices of catalyst projects with emphasis on physical issues and to identify potential areas for defining catalyst projects in the area of two region of Tehran's 18th municipality

research method:
The type of applied research and research method is descriptive-analytic. Data gathering tools included questionnaire, library studies and observation. In the location section, the AHP method is used in GIS software.

The results show that different indices such as population and construction densities, age and quality of buildings, level of culture and literacy of the community, mixing and diversity of uses and activities, etc. to locate catalyst projects with emphasis on physical dimension is extracted from the views of scholars. Also, by applying these indices to locate potential zones, for defining catalyst projects in the problematic texture in the area of two region of Tehran's 18th municipality, 3.99 hectares (14.04%) of the worn out texture of the studied area have the least ability to formulate catalyst projects (the western part of the contaminated area of the region two) and 9.66 hectares ( 34%) of the studied area has the most ability to implement the catalyst projects (the eastern part of the area of region two) and the major areas suitable for placement in the central parts of the texture and areas of Shahid Rajaee and Sadeghieh.
