The rapid increase in the population and the increase in the rate of urbanization is one of the concerns of the city authorities for the management of construction and demolition waste. These solid wastes lead to the destruction of soil, air and water bodies and pose serious risks to human health. The present study focuses on the combination of AHP model approach with GIS for the optimal location of construction and demolition waste burial site in Haftkal city (Khuzestan province). In this research, with the help of experts' opinion, 3 groups of main criteria, 12 sub-criteria and also benefiting from the hierarchical analysis of the positioning process were used. With the help of Expert Choice software, the comparison of the main criteria and sub-criteria was done, and among the three groups of main criteria, the morphological criterion with a weight of 0.443 has the most weight, and among the sub-criteria, slope (0.800), geology (0.293), distance They got the most weight from underground water wells (0.293) and distance from roads (0.411).The obtained weights were applied to each of the criterion layers in Arc GIS software with the help of the Weighted Sum command, and the final result of this research showed that 27229.79 hectares of land in Haftkal city is in a very suitable area for the construction of a construction and demolition waste burial site.

Establishing tourism eco-camps is a key strategy for sustainable tourism development, particularly in religious tourism destinations, as it enhances their appeal and economic value while preserving spiritual and historical sites. Weis Al-Qarn, a popular tourist destination in Kermanshah Province, attracts a significant number of visitors annually. Introducing a tourism eco-camp in this area can be a crucial step towards achieving sustainable religious tourism objectives. Hence, this quantitative and applied research aimed to identify an appropriate location for a tourism eco-camp in the tourist area of Weis Al-Qarn in Kermanshah Province. To accomplish this objective, 12 criteria, including elevation, slope, annual solar radiation angle, geology, proximity to landslide areas, distance from the river, distance from roads, land use, vegetation differentiation index, distance from cemeteries, distance from the court of Weis Al-Qarn, and proximity to paragliding sites, were employed. The data analysis involved using the overlay method and the Weighted Sum tool in ArcGIS software. The research findings revealed that out of the total investigated area of 219.39 ha for the tourism eco-camp construction, approximately 32.2 ha were classified as highly suitable, 55.03 ha as suitable, 60.76 ha as moderately suitable, 45.73 ha as unsuitable, and 25.66 ha as highly unsuitable. The highly suitable area was predominantly located in the southern and southeastern parts of the study area with a limited portion in the western section.

Problem Statement: 

The location and architectural design of administrative sites play a crucial role in achieving passive defense goals and facilitating decision-making at various strategic levels. Office spaces are a key consideration for urban planners and designers. 

 This applied research, utilizing a descriptive-analytical approach, aimed to identify and design administrative sites in the 4th district of Tabriz City. 

 The study employed documentary methods and questionnaires to gather information. The research population consisted of 30 individuals with 28 ones selected as the statistical sample by using Cochran's formula. The IHWP model's positioning was analyzed using GIS software and the AHP method in Expert Choice software was utilized to assess the impact of architectural design indicators on office spaces within the sample.

Notably, desirability tended to decrease from north to south. Furthermore, the study examined 47 architectural indicators for office building design, highlighting the necessity of incorporating secure underground spaces for emergency shelter and safeguarding sensitive areas within office buildings to enhance resilience against potential threats. Ultimately, the research presented the placement and design requirements for office buildings.

Urban green space is deemed as a kind of application which its distribution and diffusion across cities bear a great deal of significance and is regarded as the breathing lungs of cities. Green spaces should sport such components as facilities, easy accessibility, suitable distribution across cities and proper area to be able to perform their roles properly.

Purpose of the research: 

This study wants to identify suitable places for the construction of new green spaces by locating urban green spaces, using by GIS and AHP model, in region 3 of Kermanshah, based on standard criteria.

This is an application-oriented kind of research being undertaken through descriptive-analytical methods endeavoring to identify the optimal locations for establishing new green spaces in the third division of the metropolis of Kermanshah according to the principles of positioning. For this purpose, such criteria as proximity to lands with residential applications, street networks, training applications, cultural applications, proximity to rivers, existence of wastelands, distance from green spaces, workshops and factories alongside multi-criteria decision making method (AHP) in the environment of Arc GIS have been utilized.

Geographical Territory: 

The study area is Region 3 of Kermanshah which is located in the southeast of Kermanshah, with an area about 1886 hectares and the population of about 165023 people.

The results demonstrate that per capita green space of the third division of Kermanshah is very low compared with a suitable and optimum standard and additionally, the manner of green spaces’ distribution, diffusion and their function radii in the before-mentioned region show that they are not in line with the condition of the region, in such a way that more than 20% of the population of the before-said region are deprived of an appropriate coverage by green spaces. The final map shows that the western, southern, central and eastern parts of the region are the best locations to establish green spaces in the third division of the metropolis of Kermanshah.

By analyzing the mentioned parameters, suitable places were identified for the construction of new green spaces considering that AHP Model be used in future studies to evaluate green space in regions of Kermanshah.

Choosing the optimal location for emergency or temporary accommodation of crisis-affected populations is one of the issues that is always considered by responsible organizations in crisis management. The city of Isfahan, being located near two very important nuclear centers within a radius of 10 and 100 km and for various political reasons, can be the main focus of military attacks as well as terrorist attacks. At a time when the greatest focus is on urban terrorist attacks and there is a very high probability of such attacks in the city of Isfahan, it seems that addressing the issue of temporary accommodation after the attack can be considered as one of the main categories. Passive defense related issues.

The main purpose of this study is to analyze the spatial location of temporary housing in Isfahan with a passive defense approach.

This research is descriptive-analytical research in terms of nature and method and applied research in terms of purpose. In order to achieve the objectives of the research, using spatial data and performing relevant analyzes in the GIS and multi-criteria decision model AHP, VIKOR has been taken.

The city of Isfahan with a longitude of 51 degrees and 38 minutes east and a latitude of 32 degrees and 38 minutes north and an area of 550 square kilometers.

The results show that among the criteria affecting the location of temporary housing, the land slope criterion with a score of 0.097 is the most important and the criterion of access to welfare service complexes with a score of 0.021 is the least important criterion according to experts.

According to the studies, the lands of the northeastern part (lands between Rahmatabad and Kameshcheh areas) of 30 km are suitable for temporary accommodation.

Waste management is one of the major challenges of urban management in different parts of the world. This problem is more severe in developing countries, which contain a large part of the world's population. The current research is to locate the landfill site selection in Haftkal county, Khuzestan. In this study, three main morphological, environmental and socio-economic criteria were considered. Sub-criteria include slope, elevation, geology, distance from faults, distance from water wells, distance from water surface, distance from roads, distance from oil and gas pipelines, distance from high voltage power transmission lines, distance from residential areas, distance from protected areas and landuse. According to the conditions of the city and with the help of experts' opinion, the main morphological criterion with 0.443 was assigned the most points and importance among the main criteria .Also among the sub-criteria slope, geology, distance from underground water wells and distance from roads got the most points. In this study, Geographic Information System techniques such as Weighted Sum, Fuzzy Overlay and Boolean was used and among the used Fuzzy Sum and Weighted Sum methods introduced the most suitable lands for the construction of a landfill site and the methods of Fuzzy Gamma 0.3 and Fuzzy Product were the most strict functions and they identified 171.14 square kilometers and 124.01 square kilometers of land in Haftkal as suitable for the construction of a landfill site. According to Boolean's logic the current landfill site of Haftkal is located in an inappropriate place and in the other of the studied methods it is in the average range.

Threats to urban areas are known today as a common phenomenon in all natural and unnatural crises. With the increase of natural crises, insecurity and destructive internal and external wars and the targeting of management and command centers, including governorates, the use of passive defense principles in locating government offices, especially governorates, becomes increasingly important. Considering the proximity of Ardabil city to the northern and northwestern borders of the country and also considering the fact that the governorate building of Ardabil city is located in the center of the city with poor access and traffic congestion, therefore, the present research aims to identify a new place to build The building of the governorate of Ardabil city has been done using indicators and principles of passive defense. This research is applied in terms of purpose and descriptive and analytical in terms of nature. In line with the discussion framework, 23 indicators were prepared in the form of 6 components of compatibility, comfort, utility, efficiency, health and safety standards and passive defense. The collected data were weighted in the SuperDecision software, then mapped in the GIS environment and finally zoned using the TOPSIS technique.

Adherence to non-operating defense principles in locating infrastructure, especially military centers, can reduce vulnerability and damage in times of danger and crisis and any military threat. There are several factors affecting this location, most of which are natural geographic (climatic and geomorphological) factors. Considering the development of cities and the placement of military centers within the urban context and the lack of adherence to non-operational defense principles in their placement and construction in the past, as well as the need to relocate most of the existing military centers at the provincial level, the importance of the case doubles. One of the main goals of the research is. Two groups of data were used in this study. Climatic data obtained from the Provincial Meteorological Organization and other data obtained from topographic and geological maps and related organizations The present study deals with the role of climatic elements and other effective factors in locating military sites. The purpose is to identify areas that are prone to non-operating defense principles. The strategic position of the East Azerbaijan Province in northwestern Iran in order to align with the Republic of Azerbaijan and Armenia and the Nakhchivan Autonomous Republic and to position itself on the European and Central Asian communication axis further emphasizes the importance of non-operational defense principles in locating sensitive and military centers. . The research method in this research is based on the Network Analysis Process (ANP) and GIS analysis. After weighting the layers and overlapping them and examining the principles of non-operating defense, the final mapping was prepared and the results show that among the factors Effective in locating military centers in the study area, climatic factors have the highest weight (0.34).

Organizing urban furniture as one of the most important elements of the urban environment, has a significant contribution to the desirability and pleasantness of the space from the citizens' point of view, and the lack of planning or incomplete planning in the field of urban furniture contributes to the inefficiency of these elements. Accordingly, considering the importance and role of urban furniture in the urban landscape and also the impact it has on the lives of city residents, the present study evaluates the design and location of urban furniture elements and variables in the city and the situation of Gorgan in terms of furniture. Urban has been examined. The present research is an applied research based on the purpose of the study and is analytical-descriptive in terms of research method. Two field methods and documentary studies have been used to collect information on the current situation. To analyze the data of the questionnaire, Spss, Excel software and Kruskal-Wallis statistical test and also for spatial analysis of urban furniture elements in Gorgan and preparing a map, Arc GIS software was used. The results obtained from the research show that in designing and manufacturing city furniture, standard principles and attention to local culture have not been observed. Also, in examining the location of urban furniture elements, no special attention has been paid to the selection and location of urban furniture components and the necessary standards have not been observed and it is not functionally in a favorable condition.

The quality of urban green space and its distribution is one of the important factors in urban sustainable development. Appropriate distribution and accessibility of urban green space are the requirements of new urbanism. The city of Maragheh is one of the middle cities of East Azerbaijan province in which the distribution of urban green space is inappropriate. Accordingly, in this study, with the aim of helping to optimize the green space of this city, a method for analyzing the existing land-uses and locating neighborhood parks has been presented. In this process, the criteria including land priorities, access to secondary and main arteries, proximity to educational and cultural centers, avoidance of inconsistent uses, centrality to the neighborhood, and appropriate distance from existing parks were considered as factors of assessment. In this order, Analytic Hierarchy Process (AHP) and TOPSIS, and fuzzy theory have been used in the GIS software environment. The results show that 13.3% of Maragheh city are completely compatible with the construction of neighborhood parks and 6% are completely incompatible. The results also show the high efficiency of the proposed method in analyzing land uses and selecting suitable areas for park development in neighboring units.

Medical services are one of the most important basic needs of human society, which the current research addresses in the direction of locating medical services in Tabriz metropolis (case study: Taleghani, Mansour and Baghmisheh areas). In this research, we first identified the target areasAnd by using Arc GIS software, we showed the map of the regions and then we used the Analytical Hierarchy (AHP) method. It includes: communication network, security, population, centrality, land, compatibility, and then we defined sub-criteria for each of them. To perform this method, we obtained the final weight matrix by using two-way comparison for each of the criteria and sub-criteria. It should be noted that we have used EXCEL software to perform calculations.Zone A (Taleghani), Zone B (Mansour) and Zone C (Baghmisheh). Based on the data obtained from the analysis of criteria, sub-criteria and options, area A (Taleghani) was identified as the most appropriate and most suitable place to establish a treatment center with a final weight of 0.01134015 due to the large number of residents and the conditions of the area.

In recent decades, the metropolis of Mashhad has experienced a huge horizontal expansion and growth, and the annexation of the surrounding villages to the city has been common. In this regard, the newly urbanized areas are located on the outskirts of the city,which are considered the junction of the suburbs with the city and called Pirashahr in the form of separate development in only three urban areas, including Toos,Shahid Bahonar and Mehregan. The result of the present study is descriptive-analytical and based on documentary and survey methods following the effect of land location in isolated suburban areas in Mashhad on controlling or accelerating the process of dysfunctional tissue and also determining isolated suburban area in Mashhad with more success in the field. Elements of land location elements(including demographic,social and cultural elements-economic elements-administrative,defense and securityelements-geographical, natural and environmental elements-spatial-physical elements).The results of the research hypothesis using paired t-test and one-way analysis of variance showed Separate urban sub-districts have improved their economic, quality of life and welfare services after accession.In the field of environment no different is observed compared to the past and in the social field, negative changes have occurred. In the QoL index, Toos area and in the social index,Bahonar town have had a better situation. Also, the results of fuzzy TOPSIS showed that in isolated metropolitan areas, the isolated area of Toos in controlling the growth of dysfunctional tissue and the realization of land location elements had a better performance than Shahid Bahonar town and Mehregan town in order to prevent growth and Expansion of dysfunctional tissues in Shahid Bahonar and Mehregan towns,in the field of planning,considered the necessary measures,especially in the environmental and social fields.

The rapid growth of population and urbanization in recent decades has created many problems in human daily life. One of the important issues in this connection is urban transportation, especially public transportation, and it is of great interest today. Studying the effective factors and evaluating the location of subway stations is one of the important and necessary issues in the urban context. The importance and prestige of any city depends on its city services. The more these services and facilities are at an ideal level, the more comfortable the conditions are for the citizens' lives and the more the satisfaction of the citizens, which is one of the most important urban services of public transportation, especially the urban subway. Accordingly, the scientific goal of this research is to use GIS analysis to identify service areas and use multi-criteria decision models to locate new stations. This research has been carried out through several steps, including identifying variables, preparing standard criteria maps, obtaining the weight of layers, applying the weight of layers, and fuzzy overlapping of layers. Analytical Network Process (ANP) model was used to weight the criteria. In the results of weighting, the distance from the fault, the distance from the parking lot, and the population without cars had the greatest impact on positioning. Finally, suitable places for the construction of the metro station were suggested.

By installing the required facilities such as recycling booths, Tehran municipality can play an important role in the promoting waste separation in order to protect environment and the goals of the sustainable development. The rate of the collection of daily dry wastes by 460 recycling booths is about 40 tons throughout the city of Tehran, out of which about 32% (12.8 tons daily) is received from the citizens by means of 81 recycling booths placed in the western areas. The aim of this article is to produce a model for dry waste management of the recycling booths placed in the western parts of Tehran. The instruments used for the purpose is the ARC GIS software. The method used in this article is descriptive-analytical and applied method. Due to the spatial characteristic of locating and lack of finality of urban problems, the basis of this research is to prepare layers of information based on the factors influential in locating recycling booths and their incorporation and overlapping in the ARCGIS software domain, using AHP and Fuzzy logic inference. A study of the results indicates that around fifty percent of the zones 5, 9, 21, and 22 of Tehran are considered useful for locating recycling booths, while around 74% of the existing recycling booths are not used properly. The maximum and minimum efficiencies among the existing recycling booths belong to municipality zones 5 (39%) and 22 (4%), respectively.

One of the physical factors in the development of Maragheh is the change of utilities and their conversion into residential use, which in turn have a direct impact on the process of physical development. The city of Maragheh is one of the most important cities in East Azerbaijan province, which has no exception to the rule of physical development. In this research, the characteristics of the city development process are examined physically. Statistics show the growing population in the city of Maragheh during the years 1966 to 2011. Understanding the factors affecting the physical expansion and development of cities helps understand urban growth and development trends. The study clarifies the factors that cause horizontal and physical growth of cities and, conversely, the repulsive factor of other parts of the city that are left behind by physical growth for any reason, and this explains the need for this research. The causes of urban growth are exactly the same as the origins of urban sprawl. In many cases, no distinction can be made between urban growth and urban sprawl however, it is important to have a clear understanding of the difference between urban sprawl and urban growth. The most imperative problems that have arisen from the uncontrolled growth of city due to physical development are the excessive use of land, the lack of sufficient urban facilities and equipment, the disconnection of the suburbs and thus adding to the urban problems. The purpose of this study is to study environmental and physical factors and their impact on the physical growth and development of Maragheh city and provide the best place for future development of the city. 

 In the present study, the criteria and sub-criteria and the relationships between them were first defined by the ANP method using Super Design software, and after obtaining the weight for each criterion and sub-criterion, the sub-criteria were first fuzzy and according to the weight of each of them the main criterion was obtained from the sum of these sub-criteria. Finally, the three main criteria of human, environmental and topographic parameters, considering their weight, have provided the main layer of the possibility of physical development of the city. Choosing a suitable method and approach for modeling a system depends entirely on the complexity of that system and complexity is inversely related to the amount of knowledge and understanding of our system. Fuzzy systems can be well used to model two main types of uncertainty in the phenomena. The first type is uncertainty due to the lack of knowledge and human tools in recognizing the complexities of a phenomenon.

Using the three main layers obtained for topographic, environmental and human criteria and according to the weight of each, the final location map of physical development of Maragheh city was obtained. The development map of Maragheh shows that the south-eastern parts are very unsuitable for physical development, while the north-eastern, north-western and south-western parts are suitable for development in terms of three environmental, human and topographic features. Environmental factors seem to have the greatest impact on the development and expansion of cities. According to our findings, and depicting the map of the city development over different years, the final map was obtained for the development of this city which is almost in line with the expansion of the city during the years 1996 to 2006 and 1976 to 1986. 

 With the arrival of the third wave of industrialization in Third World countries since the beginning of the twentieth century, production and income in cities, followed by increased demand for urban services and consequently urbanization has expanded. One of the effects of physical growth is related to the expansion of the outskirts of cities beyond the administrative boundaries of any city. Such urban development goes to areas outside the administrative boundaries and changes in land uses. The city of Maragheh has many limitations in terms of physical expansion due to the gardens around the city. In order to prevent the destruction of gardens and agricultural lands as well as physical expansion in line with natural and human criteria, extensive studies should be conducted. Information and data were applied in this study for the analysis of these parameters.The city of Maragheh needs to expand physically following the increase in population naturally and its increasing expansion goes on due to uncontrolled urban migration. In the present study, three main criteria of human, environmental and topography have been used. From the topographic criteria, the south-western parts are the most suitable places and the north-eastern parts of the city are the most unsuitable parts. In terms of environmental criteria, the western and south-western parts and to some extent parts of the north are suitable for development. Due to being a garden city, it is limited to gardens from the surroundings, which makes it difficult to expand from a human and environmental standards point of view. By combining three layers of environment, human and topography, the best place for the development of this city according to the final map was prepared for the optimal location of the future development the city based on ANP Fuzzy method by which it is more suitable in the west and north-west than in the south and south-west.Paying attention to horizontal expansion preserves the traditional texture of the city and single-storey buildings and prevents its vertical expansion. Although vertical expansion has advantages over horizontal spreading out, the current conditions of Maragheh city and its size, as well as its traditional texture and culture, make the need for horizontal expansion more tangible than vertical expansion.By using the right development model, both the traditional construction of the city can be preserved and the problems caused by sporadic development can be reduced, provided that the horizontal development goes in the direction that environmental and human conditions demand.

Using the traditional methods for planning the special physician offices to give health and care services is wasting time and paper. Nowadays, GIS or Geographical Information System works as a means to create a proper and efficient bank of information. One of the uses of this positioning system is the land use for special physician offices. This study aims to evaluate the spatial distribution of specialist doctor offices in Ilam City and to determine suit able zones in order to provide a desirable pattern using a descriptive-analytical method. Data collection in this research has been done through library and field methods. The statistical population of the study consists of urban management experts, 20 of whom are selected through available sampling. The research questionnaire is distributed among them. Data analysis is performed using fuzzy analytical hierarchy process (AHP) and integration with digital layers in Expert Choice and ArcGIS software. The stages for determining the locations of specialist doctor offices included preparing information layers in raster format for each criterion, classifying each information layer based on the value by using FUZZYAHP, combining all the information layers, applying the final coefficients of the FUZZYAHP model, and preparing the final map. After performing the necessary calculations and evaluations, the highest weight was given to the criterion of “population density and vulnerable population” (0.303), while the lowest weight was given to the criterion of “distance from commercial usages” (0.016). Considering the weights of the criteria and the overlap between the layers, ultimately the highly suitable areas with an area of 43 hectares, the zone with suitable location with an area of 176 hectares, the zone with relatively suitable location with an area of 225 hectares, the zone with unsuitable location with an area of 131 hectares, and the zone with highly unsuitable location with an area of 269 hectares for the establishment of specialist doctor offices in Ilam City were determined. The most suitable locations were in Area One of Ilam City Hall, zones 2 and 3; in Area Two of Ilam City Hall, zones 1 and 2; in Area Three of Ilam City Hall, zones 1, 2, and 3; and in Area Four of Ilam City Hall, zones 1, 2, and 4Expanded.

The Geographical location pattern of industries is the title of spatial planning. Industrial location based on planning to manage systematic space and in format of industrial towns provides the possibility to performance the supportive policies from fragile ecosystems. The purpose of current research is to investigate the distribution pattern of the Alborz province industrial workshops in association with the role of industrial towns. that studying this topic become possible by using library resources and documents related to the topic of the research. The statistical Society of Research is the workshops with over 10 people employees and more in the Alborz province that matching with workshop census statistics in the year 201, is about 2944 item workshop. Current research in terms of goal is practical and methodological, is a type of descriptive and analytical research. Quantitative models such as entropy coefficient and qualitative data analysis were used in the analysis of workshop distribution. According to the research findings, the distance between the entropy coefficient obtained and the number 1 is very high and shows the unbalanced distribution of industrial workshops in Alborz province. A triple pattern was identified in the establishment of the province's industrial workshops.Two-thirds of the province’s workshops formed individually. From 15 industrial town’s province, 12 towns formed spontaneous and then have been approved as industrial towns. The unplanned formation of industrial towns and the dispersal of workshops in the residential and agricultural areas of the province, it has caused many environmental problems for the region.

Reducing the vulnerability of urban facilities to decrease the amount of damage using new crisis management approaches, such as passive defense, that can be effective in creating a safe environment in cities is one of the most important objectives that urban planners and managers today seek to implement in cities. Accordingly, the present study aims to investigate the vulnerability of urban facilities in Ilam City concerning passive defense and with an emphasis on environmental threats. The research method is a descriptive-analytical method for explaining the status quo and finding answers to the research questions. The data collection method is library and field studies. Data analysis is done by combining the two AHP Fuzzy and GIS methods. The results show that based on the principles of passive defense, the City of Ilam is vulnerable to flood hazards. Furthermore, facilities of Ilam City, including electricity and gas distribution networks and most water and wastewater distribution networks, are located in safe areas of the city based on passive defense principles. However, an important part of the network of major drinking water pipelines is located in critical flood areas. In this study, safe points have been identified from the perspective of passive defense to take the necessary steps to change the path of these pipelines by the relevant organizations.
