Moreover, Iran has the second largest natural gas reserves in the world, thus the replacement of fuel CNG for gasoline can be one of the emergency solutions to deal with the overuse of gasoline and other fuel products. The appropriate location of natural gas stations can largely meet the fuel shortage and lack of access of citizens to it. in this study we examined a mathematical model developed to find suitable sites for construction of CNG stations. The purpose of this model is to minimize the costs and maximize the coverage of customers.we use Goal Programming to solve this problem. Finally, this model has been implemented in the form of a case study in Tehran. The results of the numerical analysis indicate that examples obtained from optimization of the proposed model reduce the total cost of the transportation in comparison with the present situation. Also, the sensitivity analysis performed indicates the accuracy of modeling in finding locations of the CNG stations in Tehran CP - IRAN IN - LG - eng PB - QEER PG - 179 PT - Thesis(M.A.) YR - 2015
