Application of spatial model of office sites using GIS with integrated multi criteria decision model AHP-PROMETHEE Case study: administrative site of Bakhrez city(Khorasan Razavi province)

According to national laws, the need to organize office buildings in newly established cities as office sites is raised, and increasing the benefits of operating these complexes depends on choosing the appropriate location. Proper location is very complex process due to its multifaceted nature. Therefore, it is necessary to identify the variables and combine them in the form of a comprehensive application model and formulate an application instruction.In order to achieve the main purpose of the research, first, effective criteria in locating land uses have been formulated, and in particular, administrative sites, which facilitate and make optimal choices. Since in the process of optimal location due to the multiplicity of variables and effective indicators, we need to use multi criteria decision making techniques and models in this study preferred ranking method Promethee is used. The model has been widely used in the past few years due to the capabilities defined in it based on fuzzy mathematical methods and its simplicity, and according to the 6 functions with the ability to define complete preference, relative preference, with topics. Urban planning, and specifically the issue of location, is very relevant. Since the main and sub-variables of the research should be entered into the model in a weighted manner and with specific significance coefficients. Relevant coefficients were determined by selecting the experts and performing pairwise comparisons (part of the AHP model).In the process of conducting research and in order to identify the options with the basic requirements for the location of office sites in Bakhrez city, the technique of combining layers in GIS software has been used. The identified positions included eight positions in the city, which were ranked Promethee multi criteria decision making model, and the optimal positions for the establishment of an office site in the city were introduced.
