Extended Abstract1-IntroductionA crisis is a crisis that threatens our country due to special geographical conditions. According to official statistics in the last 29 years, 1% of the country's human casualties were caused by earthquakes, and on average every year an earthquake with a magnitude of 7 on the Richter scale occurs in the country for 11 years (Attar), 2012: 8).From the point of view of geology, Iran has a zone of lithological structure such as Central Iran, Zagros, Northeastern Iran, Northwestern Iran and Azerbaijan zone, which the thrust and elevated structure of Zagros is considered as one of the most active of these zones. It includes faults such as Sahne, Durood, Qala Hatem. The seismic characteristics of Zagros show that compared to other structural zones, the frequency of earthquakes is high. The central Iranian and Arabian plates are constantly pressing on the Zagros region, and this is the reason why more earthquakes occur in Zagros than in other regions. The studied area of Kermanshah region is an earthquake zone in terms of seismicity. This province, which is located in the Zagros region, has high seismic activity. These earthquakes usually occur around known seismic faults in the province, including the High Zagros Fault (High Zagros Fault, 2014: 114). Despite numerous researches in the field of locating temporary accommodation on the subject of seismic vulnerability, its suitable and usable place after the earthquake with the approach of crisis management in urban areas has received less attention. The city of Kermanshah is a prone region in terms of earthquakes, and due to its location in a geographical area with a high risk of earthquakes, knowing the vulnerable and resistant areas and planning for the correct and appropriate location of temporary accommodation in time The occurrence of an earthquake is necessary to prevent or reduce the possible danger in this city. This research is complementary to the previous research and with more effective criteria and indicators by providing a practical, efficient, simple and logical method for locating temporary accommodation in order to prepare the city with their specific complexity in responding to crises caused by earthquakes. Is. As an example, the Ezgele earthquake in Kermanshah in 2016 with a magnitude of 3.7 on the Richter scale occurred 11 km from Ezgele section and 32 km from Sarpol-Zahab city, which killed and injured more than 12 thousand people. And since then, due to the lack of single policies in the field of emergency, temporary and permanent housing, problems have been created for housing people. Therefore, the existence of a suitable place to live in Sharat after natural hazards, especially earthquakes, is essential for the city of Kermanshah. The present study, taking into account the stages of crisis management of an earthquake-prone city, tries to address the problem of locating suitable spaces for the construction of temporary accommodation camps.2-MethodologyThis research is of an applied type and according to the investigated components, the approach that governs it is the descriptive-analytical method. The aim of the present research is to analyze the important and influential criteria for the correct location of temporary accommodation in Kermanshah city. In order to achieve this goal, in accordance with the objectives of the research, the required information has been collected using library research, documents and interviews with experts, and then the criteria used for positioning have been selected based on the positioning criteria. The current approach to spatial analysis has been carried out by using the weighted sum model and the ranking method and ArcGIS software.3-Results-Road situation: The analysis of the results of the Kermanshah city situation based on the road access index using GIS analysis software shows that 75% of the city is in the very low vulnerability zone, 7% is in the low vulnerability zone, and 5% is in the vulnerability zone. On average, 3% is in the high vulnerability zone and 10% is in the very high vulnerability zone.-Population density: Examining the results of the state of Kermanshah city based on the population density index using GIS analysis-mapping software, shows that 27% of the city is in the very low vulnerability zone, 27% in the low vulnerability zone, 26% in the medium vulnerability zone. 11% is in the high vulnerability zone and 10% is in the very high vulnerability zone.-Location to administrative, law enforcement and military centers: Examining the results of Kermanshah city status based on the index of access to administrative, law enforcement and military centers using GIS software, shows that 7% of the city area is in the very low vulnerability zone, 12% in the vulnerability zone low, 13% in the medium vulnerability zone, 12% in the high vulnerability zone and 57% in the very high vulnerability zone.-The location of fire stations: the analysis of the results of Kermanshah city based on the index of access to fire stations using GIS analysis software shows that 2 percent of the city is in the very low vulnerability zone, 5 percent in the low vulnerability zone, 8 percent in In the medium vulnerability zone, 32% is in the high vulnerability zone and 53% is in the very high vulnerability zone.-Land slope: This criterion is measured by the slope index. Examining the results of Kermanshah city status based on the land slope index using GIS analytical-mapping software, shows that 46% of the city area is in the very low vulnerability zone, 33% in the low vulnerability zone, 11% in the medium vulnerability zone, 6% in the vulnerability zone. high and 4% is in the zone of very high vulnerability.-Distance from flood-prone areas: The evaluation of the results of Kermanshah city status based on the index of distance from flood-prone areas using GIS analysis-mapping software shows that 16% of the city area is in the very low vulnerability zone, 11% in the low vulnerability zone, 19% in the low vulnerability zone. In the zone of moderate vulnerability, 25% is in the zone of high vulnerability and 29% is in the zone of very high vulnerability.-Distance from hazardous facilities: To measure this criterion, the indicators of electrical facilities, gasoline pumps, gas pumps and gas pressure reduction stations have been used in terms of their functional nature and hazard. Analyzing the results of the state of Kermanshah city based on the index of distance from dangerous facilities using GIS analytical-mapping software, it shows that 13% of the city area is in the very low vulnerability zone, 12% in the low vulnerability zone, 25% in the medium vulnerability zone. 34% is in the zone of high vulnerability and 16% is in the zone of very high vulnerability.-Status of water sources: The results of Kermanshah city situation based on the index of access to water resources using GIS analysis-mapping software show that 9% of the city is in the very low vulnerability zone, 17% in the low vulnerability zone, and 15% in the vulnerability zone. On average, 32% is in the high vulnerability zone and 27% is in the very high vulnerability zone.-Location to power sources Construction of camps and temporary accommodation sites in the power transmission routes due to the provision of lighting and the use of heating devices. The evaluation of the results of the status of Kermanshah city based on the index of access to electricity resources using GIS analytical-mapping software shows that 9% of the city area is in the very low vulnerability zone, 8% in the low vulnerability zone, 8% in the medium vulnerability zone, 26% in The zone of high vulnerability and 49% is placed in the zone of very high vulnerability.-The final map of the optimal location of temporary accommodation bases after defining the important criteria and analyzing the indicators in the studied area is as follows: The results of the combination of 9 indicators in the city of Kermanshah indicate that 1% of the city area In the area of very low desirability, 11% is in the area of low desirability, 37% is in the area of medium desirability, 38% is in the area of high desirability, and 13% is in the area of very high desirability.4-Discussion&ConclusionsIn this research, according to the nature of the research and examination of the environmental conditions of Kermanshah city and the important indicators that are selected and evaluated according to the topic. After examining the determining and influencing factors on the temporary accommodation system and identifying the factors, the results were 9 indicators, which should be applied in the present study with general and specific evaluations (relative to the conditions of the study area). It became a scientific source of consolidation. Investigating and identifying the most accurate features in choosing the location of safe shelters: (slope, access to roads, distance from centers and management, access to firefighting centers, access to water and electricity sources, distance from flood-prone areas, and distance of dangerous risks) is considered And the results of the research showed that the important criteria and options in choosing the right place for temporary accommodation are centers that are identified as the best places that are far from the river and sensitive and dangerous uses such as gas stations and pressure lines. It should be maintained strong and close to essential service centers such as medical centers and fire stations, provided with water and electricity sources, accessible by communication lines, and the probability of damage and blocking of roads should be low. Examining the points selected in the final map shows that in the city of Kermanshah, these points are suitable for use according to important criteria such as: accessibility, distance from sensitive uses, proximity to service areas and distance from flood prone areas. It is in critical condition. The results of the current research show the capability of multi-criteria decision-making methods and geographic information system in identifying areas prone to temporary settlement. Therefore, according to the findings and results of this research, it is suggested that relevant organs, departments and organizations such as the municipality, the governorate, the crisis management center of the Kermanshah Fire Organization, etc., by creating comprehensive and updated databases of all details and elements A city based on the geographic information system should always be prepared for the temporary settlement of the population in the wake of the earthquake crisis. -Preparation of basic and suitable infrastructures for selected sites such as sanitary facilities, water sources, lighting system, etc., so that in case of an earthquake, it has the necessary conditions to accommodate the population, and the need to spend time for not provide these services. Accommodation centers should be located near roads that provide access to different parts on the one hand, and on the other hand, the probability of damage and blockage of these roads is low so that the risk of cutting off access, accommodation, relief and rescue operations does not stop. Zagros seismic zone has its own seismic mechanism. The fault systems and the earthquakes that occurred there follow the special pattern of the Zagros earthquake province, so planning and management should be done by evaluating the existing conditions and taking into account all the conditions of the region and the needs of the people. be carefully examined.

Extended AbstractIntroductionManagement in general is the art and knowledge of efficient and optimal use of resources to achieve the goal, and waste management or waste management is in fact all the planning and activities in the field of waste and in order to reduce, move, convert, Decontamination or disposal of waste takes place. Waste management system consists of different parts. This system can be compared to a chain that in the absence of a loop, the chain will be broken, so the performance of each waste management will affect other parts. Although the waste problem has been solved in many cities of the country and may have become a source of prosperity for the city,In the metropolis of Ahvaz, due to the lack of a clear strategy and proper investment in recent years, it has not been able to bring prosperity to the city and always a lot of garbage in the people, has caused a huge amount of dissatisfaction of citizens. In Ghizaniyeh section of this city, since 1991, with the closure of the old landfill in the "Broumi" area, it has been set up Non-disposal of garbage in a principled manner and according to the rules in this garbage site, provides the conditions for garbage to burn in this site and the smoke from this fire will burn the residents of Sofireh village and most of the villages of Ghizaniyeh section of Ahvaz city and east of this city. Has encountered a problem. One thousand tons of city waste is transferred to the Ahvaz waste site daily. The per capita waste production in the country is 700 grams per person, this per capita in Ahvaz is more than the national average per person. According to the latest statistics, the amount of garbage collected in 24 hours is close to 800 tons, which has decreased despite the fact that garbage collectors and dry garbage collect by them.Material & MethodsAccording to the research topic, the research method is descriptive-analytical. In this regard, first, using GIS software, the situation of waste landfill in Ahvaz city has been studied, then the geographical distribution of suitable places for waste landfill in this city has been studied. For analytical work, maps that have been in the form of polygons have been turned into rasters, and maps that have been in the form of point and linear features have been determined using the Euclidean distance to determine their importance in relation to the landfill. In order to determine all the maps, the importance of classification has been applied to them. Finally, using the FAHP method, the weights obtained from this method are multiplied in the obtained layers, and the final map, which includes the current location of the Ahvaz landfill and the proposed locations, is obtained. In the next stage, using the opinions of experts living in Ahvaz, managerial, economic, environmental and social indicators have been studied. In order to analyze the data, statistical and graphical analyzes in GIS and SPSS were used.Results & DiscussionThe results of the study showed that in terms of location and environment, the ambassador landfill site is in a good condition and the problems of Ahvaz city in relation to waste disposal are due to its proper management . The studies of this study show that in the spatial survey of Safireh landfill, environmental criteria have been relatively observed. Among the landfills around the city of Ahvaz, from 5 very unsuitable to very suitable conditions, Safireh site is in a good condition, which can be said that the location of this site is suitable in terms of environmental characteristics.Conclusion According to the studies and using the opinions of experts, it can be stated that the waste problems of Ahvaz city originate from the same source, ie its production and lack of management. Also, the studies of this study showed that the economic criterion has been the most important factor in the view of experts in locating landfills. The results for the study of proper waste management at the source indicate that the component of proper waste management at the source is significant and will have a direct impact by reducing environmental effects, and the component of proper waste management at the source as one of the main factors And is decisive in reducing the environmental impact of Ahvaz. Finally, based on the research findings, suggestions were made to control the pollution of the waste site in the metropolis of Ahvaz and in the study areas.

Extended Abstract Introduction Marine tourism is one of the most attractive and most popular tourist branches that has flourished much in recent decades and has attracted a significant part of tourism economy. In the meantime, despite having extensive coastal borders in the north and south, Iran has not yet been able to provide tourists with desirable services in relation to marine tourism. The constructing of marine tourism sites in coastal areas is one of the measures that can be taken in this regard. In order to locate such sites, it is needed to take the following criteria into consideration: distance from the sea, view of the sea, exposing to the sun, land use, distance from natural hazards such as faults, floods, erosion, distance from the residential areas, distance from the rivers and lakes, distance from road networks, distance from protected areas and percentage of slope. In this regard, the present paper aims to determine the most appropriate places for the construction of marine tourism sites in the city of Tonekabon, considering the importance of quantitative and qualitative identification and assessment of the characteristics of the areas. It is hoped that managers and planners can provide the ground for developing marine tourism on the southern margin of the Caspian Sea in accordance with the available capacities, by assessing and analyzing this process in the coastal areas of this Sea. The present research seeks to answer the following question: Where are the most suitable places to build a marine tourism site in the city of Tonekabon? Materials & Methods The present research with descriptive-analytical method aims to identify the most desirable locations for the construction of marine tourism sites. The required information was collected by a library method. In order to weight the criteria under study, the opinions of 32 experts were surveyed and the AHP method was used. After determining the weight of each criterion, the information layers of each of the criteria were prepared in the GIS environment and finally, with overlaying of the information layers, the most suitable locations for the marine tourism sites were introduced. Results & Discussion According to the experts, the criteria of exposing to the sun, slope percentage, sea view, land use, severity of erosion in the area, and the criteria of distance from the sea, distance from the road networks, distance from the faults, distance from the protected areas, distance from the rivers, distance from the residential areas and distance from the areas subject to flood, were scored based on the distance (Table-1). Then, the information layers were created based on each of the criteria in the GIS environment and rated according to the weight of each criterion. Accordingly, four areas in the city of Tonekabon have been identified as more desirable compared to other points in order to locate the marine tourism sites. Conclusion The correct location of the various land uses by using tools, techniques, and scientific models and in accordance with the principles and rules of planning can be efficient in solving land use problems. Therefore, proper planning for the creation of marine tourism sites in the proposed places, in order of priority, will provide sustainable tourism development and mutually the economic development of the region. Accordingly, based on the analyses and the results of the research, the following suggestions are presented for the construction of a marine tourism site in general: - Accurate and complete identification of facilities and services available in neighboring settlements with the proposed location. - A detailed study of the proposed location for the construction of a marine tourism site - Investigation and feasibility of the deployment of activities related to the marine tourism in the proposed location. - Studying and identifying the facilities needed by tourists visiting the sea within the desired range. - Advertising and introducing the capabilities of marine tourism at national and regional levels. - Encouraging investors and local people to invest in the construction of tourism sites. - Allocating sufficient funds and credits to build the primary infrastructure. - Strengthening and improving roads and communication paths to the proposed location - Familiarizing people and authorities with the benefits of marine tourism and trying to attract their participation - Improving and enhancing the safety and security conditions within areas of interest.

Introduction
The problem of locating bank branches is classified asNP-Hard problem which can possibly be solved only in exponential time by the increase in the number of banks and the large number of customers, especially when the location model includes various datasets, several objectives and constraints. As a consequence, we need to use heuristic methods to solve these types of problems. Also, since majority of data and analyses applied in the locating problems are spatial; GIScience’s abilities should be employed besides optimization methods.
Nowadays, to perform particular financial tasks, bank customers often need to be present at their bank. For the sake of its customers, a bank should increase its branches in the city to attract more customers in the race with competing banks. However, establishing new branches is too expensive and banks prefer to carry out an optimal location finding procedure. Such procedures should consider many criteria and objectives including spatial data of customers, new and existing bank branches as well as the level of attraction of banks. Customers often select a bank that is closer to them, has better services or financial records and also consider other human or physical factors. Hence, planning to increase the number of customers for a new branch of a bank considering spatial criteria and various other objectives appears necessary.
Materials & Methods
This paper determines the location of bank branches. Finding an optimum site for branches depends on many factors and these problems are known as NP-hard problems. Despite being approximate methods, meta-heuristic algorithms seem suitable tools for solving NP-hard problems. In this paper, Grey Wolf Optimizer (GWO), Genetic Algorithms (GA), Particle Swarm Optimization (PSO), Cultural Algorithms (CA) and Invasive Weed Optimization (IWO) are applied for finding the best location for bank branches. From marketing point of view, the aim is to attract more customers while the number of attracted people to a new branch should be acceptable. The new methods have capability to find the optimum location for new branches. The location of a new branch should be as far away as possible from branches of the same bank. The other condition is that the total number of customers for the new branch should not be less than a specified number, while the new branch should not attract customers of old branches of the same bank. To fulfill this propose, a part of the city of Tabriz was selected for implementation.The assumptions for the defined problem can be expressed as the following statements:
a)We consider four different banks (Melli, Mellat, Sepah and Mehr) in our study area.
b)Population density (of people over 15 years of age) is available at the building block level.
c)Banks have infinite capacity for accepting customers.
d)Each customer refers to only one bank.
e)New bank branches should have maximum distance from the branches of the same bank, so that, it attracts minimum number of customers from branches of the same bank.
Conclusion
To evaluate the quality and accuracy of the algorithms, several iterations are performed. The results of statistical and final tests indicate that the accuracy and convergence speed of Invasive Weed Optimization are more than other Algorithms in finding optimal location of bank branches.

The present research was conducted with the aim of locating the susceptible military centers and determining the favorable areas for its construction in a part of dense forests in Golestan province-Ali Abad Katoulcity, using the Analytical Hierarchy Process (AHP) and Geographic Information System (GIS). For this purpose, using defense experts’ opinions, university professors, military experts and resources review, information layers, slope percentage, slope direction, elevation classes, distance from the canal network, distance from the road, distance from villages, lithology, density of vegetation and distance from urban areas as factors affecting the location of susceptible military centers in forest areas were identified and the aforementioned maps were prepared and digitized in the GIS environment.In the next step, standard AHP forms were prepared and assigned to different experts in order to weight and prioritize effective factors. Weighted forms were collected and each of them was analyzed separately in Expert Choice software and AHP module in Arc GIS 9.3 software. Finally, the weight of each of the criteria and sub-criteria related to the target was determined. The results of the evaluation showed that the three factors of distance from the city (0.321), distance from the road (0.217) and lithology (0.176) have had the most impacts on the location of the susceptible defense centers of the study area, while the density of the vegetation (0.023) and direction of slope (0.017) have had the least effects. Eventually, the final potential map of the susceptible defense centers was prepared using the AHP model in the GIS software environment, and was divided into four subcategories of low potential (9.07%), medium (41.8%), high (30.01%) and very high (19.13%).

Daily increase in the production of municipal waste is one of the most important factors threatening the health of the global environment. At present, burying the municipal waste is the most significant method of waste disposal in many countries, including Iran. The type of the research is developmental and applied, and the method of investigation is descriptive and analytical.In this research, SPSS, 10 and ARC / GIS software were used for spatial and statistical analysis. The information gathering in this research was a library collection consisting of: sources of books and note-taking and the use of Internet articles, seminars and theses.The purpose of this paper is to determine the suitable location for burying municipal waste materials in Tonekabon city. In the process of locating land suitable for landfill, 9 information layers including layers of distance from urban and rural areas, groundwater level, distance from the river, land use, soil type, rainfall, distance from communication routes, land use and classified slope , were used in location operation using the overlapping process and the hierarchical analysis process (AHP) by extracting effective weights.Based on the results obtained in this research, 12.34 hectares of the total area of Tonekabon city is of extremely strong importance, which possess 0.12% of the area. Also, 1827.90 hectares of the area is of very strong significance, which holds 6.95% of the area. This is despite the fact that. 9904.82 ha of the area has a low priority in terms of importance which holds 37.70% of the area with medium importance and 7233.63 hectares of about 27.53% of the area.The region with a strong significance with an area of 7267.37 and 27.66%, and the region with very strong significance with an area of 1827.99 and 6.9%, have been taken into consideration for proposing landfill for the municipal solid waste materials.

Places have fundamental differences in terms of scale and natural characteristics; in a complex way, they are overlapping and interdependent. Therefore, no map of the places in the world can be drawn to show definite boundaries. There are many examples of difference in places: Sand Book (1984), about changing the spatial distribution of the industry and moving it away from interconnected urban areas - which turned out as a motivation for a full research program with general title of "Localising Program "-, explains this matter through local fabric. Every place bounded by a border is a land whose characteristics can be clearly expressed; its boundaries can be defined - whether on the ground or on the map - these borders can be defended, and their qualities can be specified. Therefore, governments’ understanding of the locating process is important for understanding how contemporary society behaves; the economy associated with the place of the capitalist system is based on competition. The provision of the interests of every place’s inhabitants has to be largely based on opposition to the interests of the inhabitants of other places, which often require the spread of positive view of the fellow-citizens and negative opinions towards the strangers. For sustainable urban development, the characteristics of the place where the city is set or is intended to be set is of great and decisive importance. The development of urban location is one of the basic steps taken by the governments for the well-being of the people living in the city. Since humans are interdependent and not able to live, progress, and develop without communication, places of human life, whether rural or urban areas are interdependent and related to each other in a way that It is not possible for one to develop without the others; this mutual interaction of places will cause their development. The nature of places can be summarized as follows: 1. Places are created by society. 2. Places make their own counterparts. 3. People have control over places and can change them. 4. Locations are not separate and independent from each other. In this research, we tried to investigate the relationship between city location and sustainable urban development as well as city location’s role in urban places; the method of research is descriptive-analytic.

The present study describes and compares the spatial method and spatial statistics by a combination of different methods of science in different fields such as multiple criteria analysis of GIS. The ultimate goal of this method is to assess the appropriateness of the area in question in order to determine the optimal location for landfill. In this context, the first step is the formation of a hierarchical structure of multiple criteria. Next, it is using the spatial analysis process to establish evaluation criteria, these based on the laws of Greece and the European Union, and also on the basis of practical and feasible international guidelines. The relative importance of the assessment criteria is determined based on the hierarchical structure and, using simple weighing model, suitable sites for landfill in the study area are determined. as a result, suitable locations are ranked from 0 to 10, which is from the lowest to the best, respectively. The last stage is the process of spatial clusters, which are designed to represent the most appropriate area. The initial ranking permits the selection of suitable places for burial from among existing places. The application and implementation of the proposed method on the Lemnos island in the north of the Aegean Sea showed that 9.3% of the studied area was suitable for burials above the 9th level.
