The purpose of this study is to analyze the location of urban green space in District 4 of Tehran and determine suitable locations for creating green space. Proper location of green space in the appearance of cities, in addition to aesthetic and recreational aspects, has an important role in reducing air pollution and maintaining the balance of the environment and has positive social effects such as vitality and vitality. The research method was descriptive-analytical and the effective criteria in locating the green space were determined using library studies and expert opinions. Parallel comparison of criteria with each other was performed using Chang method (fuzzy AHP). The criteria map was prepared in GIS environment and standardized in IDRISI environment. Then, using the OWA technique, the sequential weights of the criteria were calculated and the final green space location map was obtained. The results showed that the distance from residential centers with 0.157 and the distance from industrial centers with 0.053 have the highest and lowest standard weights, respectively, in the appropriate location of urban green space. Therefore, the most suitable and unsuitable places to create green space were determined according to the priority of parameters and compatibility of uses with green space. The novelty of this study is in using OWA technique in locating green space for District 4 of Tehran.

The aim of this study was to evaluate the location of sports activities with emphasis on social justice and spatial balance in Shiraz. The research method was descriptive-analytical based on 11 criteria. To examine the criteria from the layers of proximity to compatible uses, the following variables were used: Non-proximity to incompatible uses, access to public transportation, access to public parking, access to the arterial transportation network, determining the radius of performance at regional and transregional scales, consideration of the approved use of detailed plan, young population, population density, available sports per capita and the lack of inappropriate slope. In order to determine the priority of each criterion, a researcher-made questionnaire was completed by 40 experts, then by forming a pair of data comparison matrix, the score of each criterion was determined by the experts and 7 priorities were extracted. The results revealed that the fuzzy overlap method had more flexibility than the index overlap. The results of the two methods shared about 60%. From the research findings, it can be concluded that the use of GIS and AHP is a suitable method for evaluating location, and planners and city managers are recommended to use the results of this research to locate new sports centers. The innovation of this research is the use of several combined analytical methods in the GIS context.

The purpose of this study was to determine the appropriate locations of fuel supply stations (CNG) according to the existing criteria in the western areas of Tehran. In this regard, by using GIS, a map of effective parameters in locating gas refueling stations, such as: population density, passages and access, land slope, compatible and incompatible uses was prepared. By utilizing the Analytic Hierarchy Process (AHP) model parallel comparisons between criteria were performed and the importance and weight of each criterion was determined by using Expert Choice software. The results of weighing the criteria showed that the benchmarks of fire, access and population density had the greatest impact on creating suitable locations for gas refueling, respectively, and the development of gas stations in the western part of Tehran Municipality has not been done based on population needs of different areas. The output map obtained by spatial analysis and AHP indicated that among the available stations, about 29% of them are located in areas with good potential and 71% of places are in places with medium potential and no places are located in areas with unsuitable potential. Also, 32.53% of the areas have suitable potential, 43.76% have medium potential and 23.7% have inappropriate potential for construction of refueling station. The novelty of the present study is that it examines a set of effective parameters.

The purpose of this study was to determine an appropriate distance for the construction of a new university branch (unit) or the merger of existing branches based on the reduction of students and the absence of the need for a university based on standard distance using the arrangement approach. The research method is applied in terms of purpose and descriptive-analytical in terms of nature. In the present study, four centers and university units of Payam-e-Noor in the south of West Azerbaijan province (Miandoab-Shahindaj-Chaharborj-Keshavarz) were studied in terms of scope of student enrollment and optimal location, and the standard distance for student admission was determined. The results showed that the spatial distribution of student enrollment in the region was heterogeneous and university units were not located correctly relative to their centers. Also, Payam-e-Noor, the center of Miandoab, was the most suitable place in the region and the center of Shahindaj was the most unsuitable position. In the end, the most suitable place for students in this area, 11 km of Miandoab road to Shahindaj was suggested.

The purpose of this article is to analyze the sustainability of urban neighborhoods with emphasis on the spatial distribution system of urban facilities in neighborhoods of region one of Tehran. Access to urban facilities is one of the important factors in the sustainability of neighborhoods. Public spaces and urban facilities are a vital part of our daily lives in the city. The research method was descriptive-analytical. Niavaran, Emamzadeh, Rostamabad, Naft, Velenjak, Darabad and Qeytariyeh neighborhoods in region 1 of Tehran by random method as the study area. were chosen. Data were collected using documentary method and extracting maps of neighborhoods and residential parts of the neighborhoods from relevant organizations, and finally, using GIS and fuzzy logic, the quality of neighborhoods' access to neighborhood elements was determined. The results showed that neighborhoods in general are fundamentally different in terms of access to neighborhood facilities, Although they are in good condition in some elements, such as access to the park, they are generally far from ideal.

The purpose of this study was to present an analytical model of morphological dimensions of the entrance, based on the phenomenological approach and study of the main inputs of Tehran. The methodology of this article was based on qualitative- Survey methods. Since the study of urban entrances has not been studied from the perspective of phenomenological approach, research innovation is in terms of approach and case study. Data collection was built upon document analysis, complete observer and questionnaire survey (108 users) and they were analyzed through qualitative – quantitative methods. The results of the expert -based survey showed: All of the entrances to Tehran are inappropriate regarding the identification and semi-appropriate concerning the orientation. The results of the user-based survey confirmed expert-based findings and showed: Saveh with a score of 77.8% in all of the identification dimensions had the worst position and in regard the orientation, its condition was semi-appropriate (56%). Damavand with a score of 66.7% was in the best condition. In relation to the type of environmental characters, Saveh had just natural elements, while Damavand with a score of 88% in green spaces and with a score of 63% in its potential for the activities was in the best position. Karaj was in the next position, because of the physical elements (64%) and unique land uses (66%). Although in all of the entrances, the final level of inside-ness had not existed, in Damavand’s entrance (11%), it existed a little. Based on findings, for having a successful entrance, creating the “identification” and “orientation” should be considered. The innovation of this research is in conducting a study for the city of Tehran.
