Then, with the help of the Fuzzy Dimetal method, the effectiveness and effectiveness ofthe criteria were investigated. The results showed that the "principle of justice" criterion has the most influence among the criteria and has the most interaction with other studied factors. On the other hand, the effectiveness of the "efficiency" criterion is more than others. In the next step, the fuzzy network analysis method was used. The results showed that the criterion of sustainability with a weight of 0.3412 ranked first, the criterion of operationality with a weight of 0.1051 ranked second and the criterion of local independence with a weight of 0.0983 ranked third. Also, in the prioritization of the sectors, the urban housing sector with a weight of 0.5219 has won the first place, the waste and urban garbage sector with a weight of 0.1542 has won the second place, and the welfare, entertainment, commercial sector has won the third place with a weight of 0.1471.
