        Due to the central role of the city, Tehran has been associated with increasing population and density, and consequently in providing services and facilities in various fields, due to lack of and, in some cases, due to the lack of appropriate geographical distribution of applications, there are shortcomings Is. The fuel filling stations network is one of the components of the municipal services network that acts as a fuel supplier to the intercity transportation sector, which is important in terms of traffic considerations, urbanization, safety and the environment. One of the most important factors surrounding fuel supply stations (petrol stations) is their proper location. Multi-criteria decision-making models (MCDMs) are now becoming an expanding tool for addressing complex spatial decision-making problems. There are several methods in making multi-criteria decisions. Studies and evidence show that multi-criteria decision-making methods, especially the combined methods between them, provide accurate results for spatial decision-making. Due to the high population density and the density of internal and external passage overnight and the passage to the adjacent areas, Tehran's region 17 shows the need for fuel efficiency and optimal location. Therefore, the purpose of this study was to determine the appropriate location of pump-gas stations in the 17th district of Tehran and to investigate the position of the existing sites in this area, using the GIS and utilizing the fuzzy AHP combined method. Not. The research method has descriptive-analytical and applied nature in this evaluation. In order to achieve these goals, suitable criteria, consistent with the studied area and different methods have been used. Finally, by using paired comparisons and experts' opinion and calculations by the fuzzy AHP method, the final weight of the criteria has been determined. The results of the integration of information layers in ARCGIS software, while identifying suitable locations for building new stations, have analyzed the location of gas station positions, which shows that each of the 2 existing locations in the 17th district of Tehran in an appropriate and optimal position they are not.

        The purpose of this study was to design an optimal model for the development of risky investment in the Tehran Stock Exchange using the fuzzy AHP grand theory method and the research method was a combination of qualitative and quantitative.In the first stage,using the grand qualitative theory approach,the paradigm model of the research including causal conditions,intervening conditions,background conditions, strategies, consequences and the central category of risky investment are extracted and the data collection tool is in the qualitative part of the interview 20 experts have been selected for the interview.In the quantitative stage, each of the extractive categories was reviewed and verified using confirmatory factor analysis, and the data collection tool in this section was a researcher-made questionnaire that was designed based on the concepts extracted from the qualitative section. After determining the validity and reliability, this questionnaire was distributed among the members of the statistical sample and the statistical population of the quantitative section included the managers of listed companiesThe sample size was determined based on the recommendations of the confirmation models of 210 people.The results of the qualitative section show 67concepts in the form of 15subcategories and six main categories in order to develop risky investment.The results of the quantitative part also showed that each of the main and subcategories extracted from research experts can be generalized to the managers of listed companies.Paired comparison tables were performed and theweight of the components was obtainedby the modified methodof Sami et al(2009) and the categories were prioritized based on them Manuscript profile

        One of the most important opportunities in the world for facilitate trade and increase world competition is use the modern information technology and communication.Therefore, the company's approach of traditional business is changed to modern electronics. The electronic businesses are attractive because of special interests. Thus, in this situation other companies will be on framework with known keys about the active company's turnover . On the other hand, the companies are able to know superior companies in the logical situation and find the key success and also analysis their own company with superior company and find the solution to upgrade their own company by comparison and ranking of the active companies in the electronic business range. In this research we found the most important factors which are effectual on comparison and ranking that refers to expert person comments are recognized by profound reading and referring to some research sources and documents. Structural equation modeling are used because of Regarding to some measurement errors of observed variables and some difficulties between those variables. We used the fuzzy hierarchical analysis for the ranking and also doing sensitivity analysis Manuscript profile
