Spatial Analysis and Locating the Industrial Town of Jolfa Using AHP and ELECTRE Models

A suitable place for the establishment of industrial activities is one of the indispensable factors for industrial development, so addressing the issue of locating and assessing the location of industrial settlements is appropriate and the situation of these settlements in relation to each other and to the desirable location is important. The main purpose of this research is spatial and location analysis of Jolfa industrial town using combined AHP and ELECTRE methods. The type of research is applied and the research method is descriptive-analytical and documentary, library and Delphi studies have been used to collect the necessary data. After selecting the initial criteria, they were classified into four groups. Then questions and questionnaires were developed. In the Delphi method, 20 experts and specialists were polled. In this way, the data were collected and used. AHP model in Expert choice software environment was used to combine criteria and sub-criteria in order to identify and determine their weight. In the next stage, by applying the weights obtained from the AHP model in the GIS environment, the lands of Jolfa were identified. Then, completely suitable zones above 50 hectares were selected and evaluated and ranked using the ELECTRE model according to 16 important criteria involved in the optimal location of industrial settlements, and the most suitable sites were identified in order to evaluate the current location of Jolfa industrial town. The results of comparing the zones selected for the establishment of the industrial town with its current location showed that the current location of the industrial town in Jolfa does not correspond with the principles and criteria of a suitable location. One of the features of the proposed location for the construction of an industrial town in Jolfa is that the town with an area of ​​83 hectares is located at an altitude of 987 meters above the sea level and exists on lands with a slope of 2%. It should be noted that due to the presence of many micro-faults in Jolfa region, the proposed site is located at a distance of 1897.37 meters from the existing faults, away from agricultural lands, gardens and forests and in terms of lithology is located in resistant lands.
