Evaluating suitability of location User educational Using a combination of FDAHP models in GIS: Case Study, high schools in Area 2 and 4 of Ahwaz

In many large cities and dense spatial pattern of educational applications for various reasons، such as the placement of the annoying User Account industrial، military، hospitals، Oil Station، medical use… and the situation is not so good. Which cause undesirable physical and psychological impact on the quality of schools and students. Therefore، in this study high school in Ahwaz region 2 and 4، for example، has been studied. The Variables، office، residential، commercial، cultural، sports، landscape، military، religious، fire stations، Oil station، health - medical، industrial، Terminal and main street. In order to assess the effect of weighting the variables in the ultimate goal of FDAHP model is usedAfter determining the final weight of the item using Raster Calculator and multiplication، weight is applied in layers. In order to provide a final layer using the Raster Calculator and select the operand، the layers overlap with each other are combined. Final results of layer integration show that most of the schools in the district 2 are in a inappropriate state of adjacent and compatibility pattern with other adjacent uses. So spatial distribution pattern of high schools in district 2 is not eligible. spatial distribution pattern of high school in district 4 show that most schools of district 4 is in a proper state of placement and adjacent with compatible and incompatible uses. So spatial distribution pattern of high schools uses in district 4 is appropriate.
