Extended Abstract IntroductionIncreasing population and urban development, increasing use of cars, increasing the number of private cars, Also the narrow width of the streets and the lack of supply of marginal park space, especially in the central parts, have caused many problems for large and densely populated cities. Parking lots as one of the most important urban infrastructures play a major role in reducing these problems. Today, in large cities, with the correct location of public parking lots, optimally manage of urban traffic is possible by increasing the provision of services to a large number of vehicles. Materials and MethodsIn this research, first, effective criteria were extracted according to the opinion of Babol Municipality experts. The information layers of each criterion were prepared in the GIS environment and to equalize the layers, each criterion was classified, Then, the identified criteria were weighted using ANP technique and with the help of Super Decision software, and then pairwise comparisons were done. Weighted layers were combined by ANP method, were placed on top of each other in the GIS environment based on the influence of each layer (relative weight) and the map of the optimal areas for the construction of public parking lots was obtained. Results and DiscussionIn this research, the inconsistency coefficient obtained was 0.07. Criteria prioritization showed that, "Distance from the road", "Distance from offices use" and "Distance from business use" criteria with a significance coefficient of 0.25, 0.24 and 0.15 respectively had the highest weights. Arc GIS software was used to prepare the final maps. Finally, suitable places for creating public parking lots were determined by applying the final weight of the criteria and overlapping the layers. According to the final location map, areas with very high potential, areas with high capability and areas with medium capability each have 3.11, 55.75 and 36.56 percent of urban lands, respectively. Areas with very high and high potential are mostly located in the northwestern, northeastern, southwestern and central parts of the city. ConclusionThe results indicate that the spatial distribution of existing parking lots in the city is not related to the effective criteria in these parking lots. According to the residential use map and population density and due to the epidemic of private car use, there is no match between the number of parking spaces in the city and their spatial distribution and population density. The result of urban parking location zoning using the ANP model and comparing it with existing parking lots in the city shows that The class of areas with high capacity for parking lots is located in parts of the city where there are no parking areas and there is an urgent need to create these types of users. This factor indicates that the location of existing parking lots in Babol city has been done without considering effective factors and criteria. All parking lots are located in one part of the city and at a close distance from each other. There is a need to create many public parking lots in other parts of the city, according to the urban population, until the per capita is closer to the reality. Considering the population of Babol city, which is 250,217 people, and the number of public parking lots, which is 6, this amount per capita is very low.

Extended AbstractIntroductionPassive defense refers to a set of non-armed actions and activities which reduces the vulnerability of buildings, manpower, facilities, equipment, funds and vital arteries of the country against destructive and hostile operations of the enemy as well as natural disasters such as earthquakes and floods. The Including passive defense policies in most countries of world and especially Iran is Building public shelters to protect and maintain of Citizens' lives, also minimizing possible damages in the human domain. But what is important in Proportion with the proposed policy, location and choice of place is suitable for the construction of urban shelters. That People can take refuge to these shelters during enemy attacks or during natural crises. For this end, the aim of doing this study is locating potential areas of urban shelters based on passive defense principles in Ilam city. Materials & MethodsPresent research In terms of the purpose, is of the type applied research and in terms of the nature and method of investigation, is of the type descriptive-analytical. Also, in terms of the data collection method, is included in the category of documentary and field research.

Extended AbstractIntroductionDefense - security issues are always one of the most important factors in planning, and neglecting this important issue can have dire consequences in the national security of a country. So, Choosing the best location and defense-security locating of military bases has an important role in the process of providing security and fighting against the country's threats. In this context, identification of appropriate natural and human factors and criteria in defense-security positioning are important issues in this regard. Therefore, considering the importance of this issue, the purpose of this study is to analyze the defense-security locating of military bases with emphasis on the Holy Defense period in Kermanshah province. Materials and methodsThe current research is applied in terms of purpose and its method is descriptive-analytical. The tools for collecting data and information are questionnaires and interviews. The statistical population is various military and security experts and experts in specialized fields related to security and political-military issues. Using targeted sampling, 50 experts were selected as samples. To analyze the data and answer the research questions, the exploratory unlimited cointegration rank test and the time series modeler method were used.Results and discussionsIn order to investigate this, the factors and criteria for the defense - security locating of military bases, emphasizing the period of sacred defense, investigated two general categories of natural factors, which included 12 natural criteria, and human factors with 13 human criteria. The results of the research in the field of natural criteria affecting the locating of military bases in Kermanshah province showed that out of the 12 indicators considered for this, six criteria of faulting and seismicity of the region, geographical conditions of the region, topography of the region, unstable lands and occurrence The problems of creep and subsidence, land slope and land type have played an important role in the locating of military bases. In general, the results of the identification of natural criteria showed that the highest level of influence was related to the fault index and seismicity of the region and the lowest level of influence were related to the index of the number of frost days. The results of the research in the field of human criteria affecting the location of military bases in Kermanshah province showed that among the 13 indicators considered for human criteria; Six criteria of political and security considerations, the presence of transportation security in the region, distance from urban and rural centers, distance from international borders, lack of settlement in the vicinity of infrastructure and distance from the communication network of main roads play an important role in locating of the military bases. The results showed that the highest level of influence was related to the index of considering military-security considerations in the locating of military centers and the lowest level of influence was related to the index of distance from gas transmission stations and highways.ConclusionFinally, the results of the investigation of the general natural and human factors affecting the location of military bases in Kermanshah province showed that among the two groups, the role of the human factor is greater than the natural factor, and the human factors and And human factors and its indicators have been more important in locating military bases in Kermanshah province. Therefore, for the proper locating of military bases, it is necessary to pay attention to the natural and human factors and their criteria so that during the crisis or military attacks, the military bases will suffer the least damage And in order to ensure the security of military equipment and bases and to ensure the security of the entire country, less damage should be done to military equipment and bases. since Kermanshah province is a border province in the west of Iran And the country of Iran has been attacked many times from the region of the western borders, and the most recent one was the war imposed by Iraq against Iran, which is known as the period of sacred defense, Compliance with the principles of defense-security planning is one of the necessities that should be considered more than other non-border provinces.

Introduction Iran is mostly located in arid and semi-arid regions, and groundwater is its only water resource. The present study introduces a method based on spatial zoning evaluation which takes advantage ofFuzzy Logic and Geospatial Information System to design possible sites for an underground dam, and ranks them according to their suitability. The usability of this method for the construction of an underground dam in Kabodarahang Plain in the north of Hamedan Provincewas evaluated in the present study. Materials & Methods Groundwater use is considered to be a solution of water scarcity in arid and semi-arid regions. Lack of sufficient financial resources and adequate technology as well as specific physical conditions make it difficult to provide clean water in arid areas of most developing countries. Over the past few years, underground dams has been considered as a way to overcome water scarcity in arid and semi-arid regions. The present study seeks to identify suitable locations for the construction of an underground dam in Kabodarahangplain in north of Hamadan province using fuzzy logic in GIS environment. As one of the case study areas of Qareh Chai River,KabodarahangPlain isthe largest plain of Hamedan province with an area of 3448 square kilometers and an average height of about 1789 meters above the sea level.It is located between 48°14ˊ 51 ̋ to 49° 5ˊ 11 ̋ eastern longitude and 34° 50ˊ 6 ̋ to36°14ˊ 31 ̋ Northern latitude. To reach the goal of the present study, effective parameters in the constructionof underground dam, such as land slope, positionof wells, springs and aqueducts, rivers channels, positionof faults, location of villages and cities, position of paths and the thickness of alluvium were collected from the study area. Based onthe possibility of performing different spatial analyses in geographic information system environment, zoning ofKaboodarahang plain was evaluated from the point of view of an underground dam construction usingfuzzy logic and GIS tools in the present study. Results & Discussion Similar to membership in classical series,“And” operatorin Fuzzy Logic is used when two or more different criteria can help in solving an issue. This operator extracts the minimum membership level of pixel units in a specified positionand use it in the final map.Fuzzy multiplication operator multiplies membership level of pixel units in specified positionsof different factors and use the result in the final map. This operator is used when mapsof different criteria have a subtractive effect on each other.Fuzzy gamma operator is the general form of algebraic multiplication of fuzzy multiplication and addition operators to the power of gamma. It is used when increasing and decreasing effects are present in the relations between different criteria. Following the preparation of layers in Arc Map software, Euclidean distance operator and interpolation based on triangulation method were used to convert parameters to raster layers. Based on the background research and standards used, the criteria maps were combined using fuzzy operators. Using Fuzzy membership operator, an area of 3342 hectares, using fuzzy multiplier operator an area of2393 hectare (around one percent of the study area) and using the fuzzy gamma operator, an area of 35574 hectares (10.32% of the study area) was selected as having a very good potential for underground dam construction.Slope Map is also one of the most important criteria in determining areas appropriate for underground dam construction. It is suggested to use a larger-scale topographic map to improve the accuracy and increase the possibility of errors. Intelligent algorithms can also be used to determine the threshold level for standardization of the criteria. Since different organizationswork in the field of data collection, it is also suggested to providea suitable mechanism to assess the potential of other plains through consultation and coordination with other relevant organizations. It is recommended to use other parameters and factors affecting the selection of suitable areas for the construction of underground dams, such as soil type or physical and chemical properties of soil in future studies. Conclusion Zoning maps prepared by fuzzy logic in GIS environment can be used to determine the appropriate location forthe constructionof underground dams. Fuzzy operators provide special conditions which make them more reliablecompared to traditional methods.Appropriate areas for construction of underground dam were identified in GIS environment. A decision making model can also be produced based on the input parameters.It is suggested to enter general information of the area to perform the initial investigation of potential areas and then add field study information to complete the model.

With increasing growth of urban population and urban development, the necessity of building new public service centers and determining an optimal place for them have become obvious. Due to dramatic increase in population, chaotic development of the city, and increase in the number of vehicles manufactured in the metropolis, Tehran faces a shortage of appropriate places for parking vehicles in crowded areas. Optimal locating of public parking lots is an approach and solution for traffic dilemma. Geographic information systems and Boolean logic are appropriate systems for finding the most optimal place for building Multi-story parking lots. This article investigates and evaluates multi-story parking lots in Tehran 15th district, considering parameters like attractive centers for travelers, access networks and urban passages, quality-structure, traffic junctions, different useful land uses, etc. Analytic hierarchy process (AHP) was used to weight the above mentioned parameters, and Boolean logic was used to overlap produced layers. After applying final weights retrieved from AHP model and overlapping produced layers, optimal sites for locating Multi-story parking lots were determined. Finally, suggestions were proposed according to the results and requirements of time and space.

Selecting a site for solid waste landfill is an important procedure in managing municipal solid waste and landfill sites should be selected with great precision and through a scientific process. Therefore, it is possible to select an appropriate site for solid waste landfill in accordance with environmental criteria using geographic information system. The present article is descriptive-analytic. Secondary research and field study were simultaneously used for data collection. It seeks to locate an optimal site for solid waste landfill in Faruj city. In this study, we first investigated factors and principles of locating municipal solid waste landfill according to valid resources. Then, maps of influential factors on locating municipal landfill were prepared and valuated based on information layers and spatial analyzer tool, using geographic information system. According to geological indexes, distance from the river, distance from residential area, landfill is located in an inappropriate zone. Ultimately, the maps were integrated and combined. Analyzing the final map of Faruj solid waste landfill, we concluded that locating principles and standards were disregarded and the present landfill site is in an inappropriate zone.

Annually, earthquake damnify many countries dramatically and damages human communities physically and psychologically. Regarding absolute annual average of people facing earthquake threat, Iran ranks 7th in Asia and 13th in the world. Throughout history, Qiru Karzin city has always faced devastating earthquakes which have resulted in many losses and damages in rural and urban areas. In this regard, spatial information system can play an influential role in identifying areas facing earthquake hazard, their dispersion, the quality of physical structure in danger and analyzing economic, social and demographic features of the area in danger. The present study seeks to identify secure and unsecure zones and find appropriate locations for crisis management bases in Qiru Karzin. To reach this goal, information received from different criteria is studied and classified into three classes of natural variables, physical variables and institutional-management variables. Then, information layers of different criteria are entered into GIS environment and standardized using Fuzzy linear functions. Later, maps are integrated using Fuzzy Plus. Finally, appropriate and inappropriate zones are identified regarding risk taking and construction of crisis management bases. According to the research results, three villages were selected based on their capability for creating crisis management bases in three levels. These villages will aid rural municipalities (Dehyaris) in the process of crisis management in Qiru Karzin and in reaching goals of crisis management bases using geographic information system capabilities .

Constructing new urban facilities needs a precise investigation on the right method of establishing such facilities in different areas of the city. Selecting an optimal place based on different and sometimes controversial characteristics is the first fundamental issue in correct allocation of urban facilities. This is especially important if crucial issues like human life are also considered. Thus due to the importance of endangered human lives, optimal selection of fire stations is considered to be crucial. Considering the uncertainty about information sufficiency and comprehensiveness of inferences drawn by tools like spatial information system, fuzzy model is used in combination with analytic hierarchy process. In the beginning step of the study, influential factors in locating fire stations were determined and standard maps were produced and prepared. During the study, a survey performed on the experts opinions indicated that these criteria do not have the same influence in locating stations. Thus, these criteria should be assigned different weights based on their importance and influence. Analytic hierarchy process (AHP) and Export choice software were used to weight these criteria. After collecting expert opinions and in order to avoid possible non-expert opinions, adaptability of the judgments were calculated. After verifying CR values, these weights were used in subsequent steps. In the next step, fuzzy logic was used to rate these layers. Prepared layers were transformed into fuzzy logics using different membership functions which were selected according to experts’ opinion. Finally, AHP and weighted linear combination (WLC) were used to integrate fuzzy criteria with fuzzy membership functions and calculated weights, and in this way appropriate zones for building fire stations were identified and determined. Simply relying on the map results cannot have the necessary efficiency in locating an optimal place for the fire stations. Therefore, standard functional radius of available stations were determined using network analysis in GIS environment. Then, places with a high score for building stations and those covering whole area in a standard time were selected. This research seeks to display the efficiency of applying integrative logic for ranking layers using AHP in GIS environment. The integrated model benefits from high capabilities and it can be applied for different goals (selecting the optimal place for a site) and in different spatial situations.

Experience of new cities in Iran has a long history. Cities like Abadan, Shushtrano, Zahedan, Noshahr and various industrial cities are among its examples. The strategy of new cities began after the approval of the Cabinet of Ministers in 1986, and the responsibility for the construction of these cities was delegated to civil engineering companies. However, the policy of locating new cities in our country has not been favorable and has been more concerned with the fact of state ownership of the land, neglecting other regulations of locating such as urban development capability, proximity to major economic centers, accessibility to roads, desirable distance from the mother city, paying attention to the population centers of the region, attention to the geographical and natural criteria of the region and ... As a result, the new cities have not succeeded in achieving their goals. Shahr-e-Jadid (new city) of Baharestan is one of the four new towns of Isfahan, which has a relatively good location, and has therefore succeeded in some way in attracting and settling the population.

The process of locating new cities includes regional studies, initial choice of a number of places, preparation of selection criteria, application of criteria on different places and choosing the best alternative, meaning the more appropriate place for the development of the new city. This locating has a direct effect on the success or failure of new cities and, since the place of the city has an effective role in attracting population or their absorption (assimilation) in different dimensions, the new cities that manage to accommodate for the population can achieve their aims. The locating of new cities has a direct relation to the intended aims of establishing these cities. In our country, locating of new cities has been usually carried out by the goal of absorbing the extra population of a mother-city, and the new cities whose locations have been determined around the country, are placed in connection with a mother-city. The locating of the new city of Sahand, the subject of discussion in the present paper, is in connection with a mother city (Tabriz) and with the aim of absorbing the overflow of that city’s population. The place of the new city of Sahand has been chosen without any regional view and merely by examination of a number of criteria.

It has been proved today that efficient urban management is not practical without utilizing up-to-date information on land uses and trends of their changes, the type and extent of activities, physical growth of the city, and so on. Hence a need for various information equipment in this regard has been developed, and the amount of up-to-date information has increased in organizations associated with urban affairs. The Global Positioning System (GPS), as one of the most important and reliable positioning technologies and the Geographic Information System (GIS) as a reference system of reception and optimal management of positional information, plays an important role in position-based analyses. The combination of these two systems provides new and comprehensive capabilities in position-based management.
