Abstract :

This study is based on substitution of old diesel minibuses with new ones. For this purpose 400 minibuses of Iran Khodro Diesel and Zamiyad companies productions, have been selected to be substituted with old ones. The operation and providing cost of new minibuses along with the differences between social, maintenance and fuel costs of old existing minibuses and new ones were calculated. The present value of these differences, were determined during the lifetime of the project separately and then compared with each other. According to the results, Reducing in social costs substitution the 400 old minibuses with new ones during the 30 years is 7,096,314,816 Rials and the present value of  fuel and maintenance costs differences are respectively 35,634,103,952 and 86,480,786,000 rial for 400 minibuses. The operation and providing cost of new minibuses are 239,411,200,000 for Iran Khodro Dissel and 282,163,200,000 Rials for zamiyad vehicles. The total cost of substitution the 400 old minibuses with new ones in Tehran is 110,199,995,232 Rial for Iran Khodro Diesel and 152,951,995,232 Rials for zamiyad minibuses. Totally, in spite of the considerable reduction of social, maintenance and fuel costs of this project but because of the high price of new diesel minibuses, it considers costly to be executed.
