Introduction
Developed and/or developing countries, in the lows of the time, are facing or will be
faced with an increasing urbanization phenomenon. Along with population growth,
urbanization and the concentration of industries, capital, facilities and urban services
have grown, and large cities have become the metropolis of the present-day cities
and have created irreparable problems for humanity. Therefore, the most important
consequences of such a process of urbanization, in addition to lack of proper urban
infrastructure, is the emergence of irregular and worn out urban and inbred textures
for residents and urban migrants, which will lead to numerous socio-cultural and
economic problems. This issue, in addition to the transformation of land into a scarce
social source, has made it more important in the recent decades to make optimal use
of worn-out textures, one of the main sources of land-based urbanization. Identifying
the worn out textures, analyzing issues and adopting an approach based on
managerial priorities is one of the most important criteria determining the process of
improving the worn out textures. The worn out texture includes areas that are
subject to the special activity of the municipalities due to the specific quality of the
space, social conditions, disaster safety and the poor utilization of public services, and
the modernization organization has been designated as its trustee. The existence of
worn-out textures in the city center of lzeh is one of the factors of the city's lack of
development, and in order to solve its problems and to provide the citizens' security
in the face of old and worn out construction, these areas must undergo some
changes from the type of renovation or renovation. Therefore, the existence of a
worn-out texture in the central region of lzeh makes it necessary to reflect on the
development process in this region.
Materials and Methods
The present study is applied in terms of target and is descriptive-analytic in terms of
collecting data. In order to achieve the ultimate goal of the research, firstly, the
preparation and production of data on the physical factors affecting the renovation
and modernization of worn out texture, including five main and key indicators for the
upgrading and renovation of texture, namely, the price of the building, the life and
history of the building, the type of materials, the area of the building and Access to
the context has been made. Using Fuzzy AHP, the weight of each of the indices was
extracted by the experts, and then, using the Gama, Sum, product functions and
functions in the GIS environment (ArcGIS 10.1 software), the region's powers
Renovation and restoration of worn out tissue was evaluated. The final step of the
research also included comparing the results of various fuzzy functions. The
evaluated indexes in the present study consist of physical indicators, in which 5
variables were used to identify priority areas for the renovation and improvement of
worn out tissue. The leveling of each index to different classes, as well as the
determination of membership rates, was carried out by 15 experts.
Discussion
To certain is that the physical structure of cities affected by natural, social and
economic flows has gradually undergone a change and exhaustion, and the need to
rebuild and rebuild them over the course of different periods has been felt. The
implementation of modernization and renovation projects of urban wastewaters is
due to the multiplicity of origins and the formation and developmental elements of
them with particular issues and complexities. The worn out texture and management
of them is one of the concerns of urban managers and planners. Therefore, in this
research, we tried to identify priority areas for modernization of worn texture in the
central part of lzeh city in Khuzestan province. In order to do this, five variables such
as age, price, type of material, area and access were evaluated. Each layer was
prepared and prepared in GIS environment. Since the Gama, Product, Sum and Fuzzy
AHP models were used for data analysis, the data were analyzed.
Conclusions
The results of t his study show that, according to the analysis performed by fuzzy
operators and the fuzzy hierarchical analysis model, the central regions of the tissue
are more prerequisite for modernization. This is confirmed by a more detailed and
precise Gama Fuzzy operator, in which the operator proposed areas for renovation,
which only accounted for 0.28% of the total texture contribution, as well as the
building blocks The average area of the blocks is more than 6000 meters and is far
from the main routes, and it is separated from the commercial fabric of the city,
which indicates the degree of accuracy in the analysis of this operator. From the
differences that this research has from previous studies, it is to allocate two types of
weights (bachelor and fuzzy functions) to the layers, namely, by giving the weights to
the layer in the ArcGIS environment, and quantifying the values of the physical levels
in determining the level of tissue burnout, priority Determined the worst-worn blocks
of the texture in order to upgrade or modernize it. In other words, this study, by
combining the main variables affecting tissue erosion, identifies the regions that are
in a more critical condition in terms of burnout, and in the next step, also identify the
areas for modernization in a higher grade and rank as Precise and detailed in terms of
meter and percentage (relative to all parts of the texture). The accuracy of the details
of the proposed areas causes. In other words, according to the analysis, the fuzzy
operators, as well as the fuzzy hierarchical model of the central regions to the
boundary of the texture, are generally appropriate for modernization, but this is
illustrated by the more detailed and more detailed Gama fuzzy operator. The reason
for this is the combination of reduced effects and increased fuzziness in the output
map, which has led to a more detailed and precise view. Meanwhile, factors such as
proximity to the main arteries, the commercialization of marginal areas and the high
price of land in this area have played a significant role in not choosing these areas for
modernization.
