A Risk Evaluation of Environmental Impact Assessment Using GRA Method

Abstract

Environmental Impact Assessment (EIA) is a proposed project in the environment or an assessment of the potential impact of the project, including natural, social and economic aspects. EIA in more than half of the world's countries required in some form. EIAs than their original proponents expected had very little influence. This paper institutionalizes this disparity and provides methodological reasons and for more effective use of EIA in the future recommends ways. Extensive experience in Environmental Impact Assessment (EIA), As a future environmental management tool Its objectives extent to which this is achieved has generated considerable debate. It is measured in terms of EIA 'Performance', In particular, the discussion moves away from practical implementation issues, moving towards the most important Objectives of EIA and Its place in broader decision-making contexts. Relatively weak in planning decisions implemented by EIA Empirical studies have demonstrated the influence. The objective of this thesis is for solving Scale weights are about interval-valued GRA numbers MCDM problems with unknown information are an extension of the Gray Relational Analysis (GRA) method. Of the traditional GRA method basic idea, Determination of scale weights, basically some optimization models are established. Delhi, Ladakh, Jammu and Kashmir, Andaman and Nicobar, Chandigarh, Lakshadweep taken this alternative in this method and evaluation parameters is Terrestrial, Aquatic, Economics, Society, Culture, Air pollution, waterpollution, Soil pollution, noise pollution, solid waste pollution. Traditional from this analysis Basic idea of GRA method Determines the long-range solution from the short-range and negative-best solution, but the comparison of these distances is not considered significant. As a result, Delhi has been ranked first; Similarly, Ladakh is ranked low. This paper showing, Delhi highest pollution in India.
