Examining the Environmental Effects of the Bus Manufacturing Unit of Iran Khodro Diesel Company through Entropy and LINMAP Integrated Method

The aim of conducting this research is to classify and examine the environmental effects of Iran Khodro Diesel’s bus manufacturing unit through Entropy and LINMAP integrated method. The bus manufacturing unit is one of the four car- manufacturing halls and the largest bus- manufacturing unit in the Middle East. This unit is located in Iran Khodro Diesel Company in Chahardaange area. A list of activities which affect the environment is prepared in this research and was presented to the company’s experts and the environmental experts in the form of a questionnaire. As a results the sections and activities which affected each pollutant were identified and based on that, the iron cleaning section with a weight equal to 0.318 was identified as the first effective section on water pollutants (chassis structuring and assembling), (PVC container and insulation) with a weight equal to 0.525 was first in rank regarding affecting air pollutants, PVC container and insolation with a weight equal to 0.525 was first in rank regarding being the most important aerosols spreading section and the roll test section with a weight equal to 0.315 is first in rank regarding noise pollutant. The three environments affected by the hall were prioritized by the LINMAP method and based on that, the physical and chemical environment with 0.6 weight were first in rank and the biological environment with 0.38 weight was second, and the cultural, economic, and social environment with a weight equal to 0.1 was last in rank. The essential corrective measures in the field of each activity were suggested based on the prioritization results at the end in order to decrease the environmental effects.
