analysis hierarchy process

In today’s world, spatial duality, growth of poverty-stricken urban districts and urbanization of poverty are considered as key destabilizers of sustainable urban development. And spatial justice is of special importance among planners and geographers. As a result, recognition and discernment of such urban districts is a critical step for de-escalating poverty and inequality. The research methodology of the present study is descriptive-analytical. In the present study, spatial inequalities of districts of Tabriz metropolis is analyzed through utilization of analysis hierarchy process (AHP) with three main criteria of economy, urban physicality and population, which include 11 sub-criteria. According to the level of urban development, Tabriz metropolis is divided into five zones which are developed, relatively developed, medium developed, less developed and undeveloped. The findings of the study indicate the fact that there is a steep physical and class gap between undeveloped, less developed and other zones of the metropolis. Furthermore, quality and quantity of social, economic and physical criteria of undeveloped and less developed zones are lower than other zones. We believe that continuance of the present circumstances will exacerbate inequality and urban poverty, and endanger sustainable urban development. Therefore, it is necessary for urban management to take new steps in order to more desirable and better understand this phenomenon and to apply new and efficient solutions to reduce the effects and various aspects of poverty in the city and urban slums.

Restrictions and seasonal attractions of the area can lead to confusion and perhaps cut the tourists from the region, the season of the visit is inappropriate. Therefore, it is necessary, suitable tourism zone is specified for each season. In this study to determine the suitable zone for tourism in the four seasons, the two models have been used bioclimatic (TCI) and Analytical Hierarchy Process (AHP). bioclimatic model (TCI), 7 of climatic parameters for climatic conditions, is used.: Average monthly rainfall, average temperature, average relative humidity, Maximum temperature, minimum relative humidity, mean daily sunshine hours and wind speed While the hierarchical analysis, we tried to consider the impact of climate indicators Attractions in every season. Finally, by comparing model output with reality in the region, was determined Analysis of the hierarchical model, suggest that the actual zones more than bioclimatic model, for tourists.

Today, in urban planning, land suitability analysis for urban expansion and identifying suitable land for their physical expansion is important. Therefore, the aim of this research is to identify suitable lands for future expansion of Firoozabad city and to put an emphasis on capability of geographic information system (GIS) in presenting optimum physical expansion pattern of this city. The methodology of this research is descriptive – analytical and in order to identify suitable land for physical expansion of the city, the present status of the city and its physical typology has been studied. Then, after collecting required information and using Analysis Hierarchy Process (AHP) in GIS software and after various stages including entering variables and parameters, providing new information layers, classification and valuation of variables and information layers and composition of the layers, suitable places for future expansion were determined. Considered variables and information layers in determining suitable land for future urban expansion consist of the land capability, elevations, slope, communication networks, faults, slope direction, cemeteries, rivers, historical monuments and rural areas around the city layers. Results of the study show that expansion of Firoozabad city is linear and irregular, and there is an urgent need for locating suitable lands for future expansion of city. Therefore and according to the location, these lands are mainly located in the south, south east and east of the city and these lands have better position than other parts for future expansion of city and otherwise, with the natural and artificial limitations, are not applicable for future urban expansion.
