Site Selection for Rescue Center Using Analytic Network Process and GIS Fuzzy in Yazd City

Planning for crisis management, especially urban crisis must be analyzed and reviewed by qualified methods. This discussion is interested in some sciences such as urban planning, environmental science, and crisis management. This topic is very important, because it is related to life and property of people. Basically, researches can play important role in decrease of manmade and environmental hazards. A disaster is a perceived tragedy, being either a natural calamity or man-made catastrophe. It is a hazard which has come to fruition. A hazard, in turn, is a situation that poses a level of threat to life, health, property, or that may deleteriously affect society or the environment. Various disasters like earthquake are natural hazards that kill thousands of people and destroy billions of dollars of habitat and property each year. The rapid growth of the Yazd population and its increased concentration often in hazardous areas has escalated both the frequency and the severity of natural disasters. Therefore, in order to be prepared for crisis and emergency management, and the primary safety rescue executions during disasters, it is essential to locate properly the centers of rescue and crisis management such as fire stations. The type of this paper is applied and methods are descriptive- analytic. In this paper, using a documentary study, documents and papers related to crisis management concepts are performed. In the next step, the Delphi method has been used and the parameters effective in positioning of rescue centers have been identified. The questionnaire was distributed in the form of data entry method. The questionnaires have been prepared and distributed among experts to weight them according to the measures of pair wise comparisons of criteria. The final values from the pair wise comparisons have been made by the experts, and the results of the Super Decisions matrix and computing environment requirements have been imposed. Finally, layers are classified based on the values in GIS and then multiplied by the weight of the criteria. The proper sites for rescue centers have been identified on the final map. In this study, the effective criteria in site selection of rescue centers are identified. A comparison was performed between the criteria. For formation matrix, the weight of each criterion has been calculated. The matrix has been prepared for each criterion in the GIS environment. Finally, the weight of each criterion layer has been used with common fuzzy operators and fuzzy locations for community rescue centers in the city. This systematic review and application criteria in this research can be used to locate rescue centers in other cities. The model presented in this study due to its ability to execute and their integration with GIS and multi-criteria decision methods, and fuzzy logic can be for site selection in other urban areas. The results show that for site selection of rescue centers, some methods such as multi criteria desition making and geographic information system (GIS) must be mixed. Based on the pattern presented in this paper, it can be used for site selection of urban land uses, spatially for site selection of rescue centers. With centralization of old texture in center of Yazd city, this paper must be beneficiary for equal distribution of rescue centers.
