| این مطالعه به منظور تجزیه و تحلیل آثار محیط‌زیستی کارخانۀ ایران خودرو دیزل واقع در شهرستان چهاردانگه صورت گرفته است. هدف از این تحقیق، شناسایی، طبقه‌بندی و بررسی آثار محیط‌زیستی کارخانۀ ایران خودرو دیزل به دو روش Entropy و LINMAP است. ابتدا با توجه به بازدیدهای میدانی، مصاحبه با بومیان منطقه و مطالعۀ اطلاعات پایه، آثاری که کارخانه بر سه محیط ایجاد می‌کند، شناسایی شد. آثار محیط‌زیستی مربوط به آن مشخص و در مرحلۀ بعدی برای تجزیه و تحلیل و اولویت‌بندی آثار محیط‌زیستی شناسایی‌شده، از روش تصمیم‌گیری چندشاخصه (MADM) استفاده شد. برای تجزیه و تحلیل و اولویت‌بندی سه محیط با استفاده از روش LINMAP، محیط فیزیکی و شیمیایی با وزن 6/. در اولویت اول و پس از آن محیط بیولوژیک با وزن 38/0 در رتبۀ دوم و محیط اجتماعی، اقتصادی و فرهنگی با وزن 1/0 در رتبۀ آخر قرار گرفت. در مهم‌ترین راهکار در زمینۀ کاهش آثار شناسایی‌شده، ایجاد یک سیستم مدیریت محیط‌زیستی مبتنی بر تولید پاک شامل کاربرد مستمر راهبرد محیط‌زیستی فراگیر پیشگیری در فرایندها، محصولات و خدمات به منظور افزایش کارایی و کاهش مخاطرات انسانی و محیط‌زیستی است. | ||

| Introduction The automotive industry is one of the largest industries in the world, which is also very important in our country.According to the World Bank, the automotive industry can be classified as the projects that have environmental impacts. Therefore, the review and analysis of the environmental impacts is conducted to identify the significant effects of pollution caused by the activities of the operation phase, propose reasonable solutions to minimize adverse impacts, and improve the quality of the environment with the aim of ensuring proper and correct implementation of activities in a factory. With its approximate area of 50 hectares including production, warehouse and building spaces, Iran Khodro Diesel Factory is located at 51 degrees, 81 minutes east and 35 degrees, 37 minutes north, 8 kilometers away from Savehroud, eastern north of Chahardongeh City, one of Islamshar City’s towns. We've placed the production of all kinds of trucks, buses, minibuses and vans with different uses on the agenda; and using the capabilities of more than 5000 efficient workforce in advanced production lines, paint lines, and the active departments of quality, education, engineering, etc, we expect to be able to make the name of Iran proud on the boundaries of domestic and foreign markets with high quality products. Materials and methods To analyze the impacts of the factory’s area, the Delphi method was used, in which the questionnaire of the first phase was prepared by the research team.After the questionnaire was developed and finally amended, a Delphi 14-member group was formed, which includes seven environmental specialists and five senior safety experts from the factory, and two environmental specialists of Islam Shahr’s Environmental Protection Agency. Then, the questionnaire of the first phase was distributed among them. The main parameters affecting water, air, noise and particulate matter were identified, and then the experts were asked to rank the impacts of all indicators on the whole environment, the biological environment and the health of individuals, and to express their opinions about its environmental impacts. As the intended indicators have large dispersion, Entropy method was used to weight the indicators. This method shows the amount of system information that is reflected by the criteria and the extent of uncertainty of the criteria.In other stages of the analysis, all 14 questionnaires were firstly combined together by using the geometric mean, and then a final matrix of 20 columns (indicators) and three rows (environments) was obtained, which is referred to as decision matrix (matrix D).The three environments were prioritized using the LINMAP method. Results Analysis and prioritization of indicatorsbased on Entropy method The studied indicators were analyzed and prioritized using Entropy method, according to which for indicators of water pollution, washing baths weighed 0.318 had the first priority and importance; and in the department of stain removal, it allocated to itself the last priority of water pollution with the weight of 0.044, due to less use of chemicals.The results of this method are given in Table (1). Table 1: Prioritization of indicators using Entropy method Parameter Firstpriority Weight Lastpriority Weight Water Washing bath 0.318 Stain removal 0.044 Air (skeleton and chassis assembly) -(PVC enclosure and insulation) 0.268 Welding point - Stain removal and welding 0.017 Particulate matter Iron washing 0.342 mould making 0.002 Noise Roll test 0.279 mould making 0.014 Prioritization and analysis of the studied environments based on LINMAP method Finally, as shown in Table (2), this result was obtained that the chemical and physical environment has the first priority with a weight of 0.6, and then the biological environment is in the second rank with a weight of 0.38; and social, economic, and cultural environment in the final ranking with a weight of 0.1. Table 2: The first to third priorities of environments determined by LINMAP method Options Weights Chemical and physical environment 0.6 Biological environment 0.38 Social and economic environment 0.10 Conclusion Chardange town is one of the regions which is affected by the population increase and changing the agricultural applications to other applications and sectors such as industry. The distribution and dispersion of the industrial organizations and complexes in different areas of this town and their locations inside the residential urban regions or around the populated and crowded regions, leads to many environmental effects and results and consequences, and one of these industrial complexes is Iran Khodro Diesel Company. When we use the evaluation methods, it is important that only one parameter is not taken into account, but the effects of all the parameters and their associated environmental impacts are considered simultaneously.In this study, considering the development of evaluation methods, especially the use of mathematical methods, two Entropy and LINMAP methods - as the latest methods employed used in environmental issues - were used for weighting and prioritization of the environmental parameters and the three affected environments.As each of the above indicators have a relative importance, the weights of the indicators were obtained using the Shannon's Entropy method, in order to show the results of the prioritization in more accurate manner; and to prioritize the options, the LINMAP method was used because of its ability to simultaneously weigh and prioritize indicators. Finally, this result was obtained that the most important solution to reduce the identified impacts is the creation of an environmental management system based on cleaner production, including the continuous use of a comprehensive environmental strategy for the prevention of pollution in processes, products and services, in order to increase efficiency and reduce risks to humans and the environment.There are three-month periods of monitoring, in which the trusted lab of the factory and the Environmental Protection Agency is responsible for control activities.Environment and HSE Department of the factory is responsible for monitoring and reporting. In Table (3) the most important environmental effects of the Factory and the plans and activities in order to decreases these bad effects are summarized. The period of these studies and evaluations is a 3-month period and they include the control activities of a reliable laboratory and the Environment Protection Organization. The responsible body for delivering the reports is the environmental sector and HSE of the factory. Table 3.
