Then these factors should be prioritized using the Todim model in the 22 neighborhoods of the city.

Also, prioritization based on the importance and needs of citizens has been in the AHP hierarchical matrix. The research findings indicate the extraction of 27 indicators as key factors that show the pattern of unstable distribution. The results show that according to the criteria for regeneration of dysfunctional tissues, 22 neighborhoods of Saqqez, 22, 2, 8 and 21 neighborhoods, which are located in the southwest and part of the north of the city, In contrast, neighborhoods 16, 17, 19, 6, 18, 4, 13 and 1, which are located in the southeast, somewhat northeast, west and the city center, are considered as highly inefficient neighborhoods that in between the Indicators of regeneration of deteriorated urban areas, Economic, physical (internal and external), environmental and social indicators have the highest to lowest rating.
