| Distressed fact that so far has affected many historic towns. It is crystal clear that the growth of urban fabric has disrupted by this issue and so is leaded to around. Therefore, in addition to the destruction of internal and historical texture, the substantial costs of creating new textures of the city are imposed to the cities. The aim of this research priority areas studied in order to apply the improvement and modernization. To achieve this goal, 5 main variables decay include dating, price, type of materials, area and the accessibility of textures has been used. Survey data and variables were analyzed by using fuzzy operators (Sum, Gama, Product) in GIS software environment Also, with weight bearing selection criteria, the Fuzzy Analytical Hierarchy Process (FAHP), was used in order to compare. Finally, the results obtained from the fuzzy AHP and fuzzy operators, to identify the best places for the improvement and modernization of the decay, the analogy is compered. Results obtained suggest that in accordance with the functions and models used, in the outer parts of the research context (i.e. meters with an area of post-traumatic 236103 share% 65 of total tissue) due to the proximity to the main street and construction are relatively better than the inner part of the tissue (with an area of %28 m2 i.e. 100754 percent of the total share of the tissue), a lower priority for the renewal of ppt. Moreover, based on FAHP, an area of over 47,569 m2 (with 13 percent of whole regions) applies for the development of the proposal. Of course, this applies to the operator for more details on Gama with accuracy and relative to other functions and fuzzy AHP model has been shown. |
