fuzzy analytic network process (fuzzy)

Today’s, in the process of urban decay regeneration, historic districts are emphasized as the manifestation of economic, social dimensions, and the crystallization of culture and urban identity, based on which identifying the scope of these districts is the first step to regeneration and preserve them. It is also one of the challenges of urban management and those in charge of affairs in Iran. As such, this paper aims to identify the range of historical district of Jahrom city, through a descriptive-analytical approach and utilizing documentary sources and libraries, the necessary indicators (19 indicators) are gathered in the terms of economic, social, physical-spatial dimensions, and historic.

Then, these indicators were investigated using a spatial analysis approach by combining two models of analytical network process (ANP) and Fuzzy Analytic Network Process (F-ANP) through ARC GIS software. The information required to quantify and evaluate the indicators are collected from some sources such as the official census in 2016, field perceptions, urban development plans, the extracted, and the weighted indicators in the developed model, by surveying the experts, urban management, and researchers.

Ultimately, this paper introduced the historic district of Jahrom in two zones. In this way, some indicators (1) the existence of primary market core via weight of 0.146, and (2) the existence of recorded historic monuments with weight of 0.133, obtain the highest scores to determine the historic district of Jahrom.

Moreover, the importance of the proposed dimensions has simultaneously been emphasized such as the historical, physical-spatial, economic, and social dimensions, respectively.
