Fuzzy MCDM approach for addressing composite index of water and air pollution potential of industries

Urbanization and industrialization with minimal focus on environmental pollution has resulted in rapid degradation of natural environment. A fresh look at the pollution control strategies is, therefore, necessary. An attempt has been made to address the problem and a new formalism is proposed for ranking of industries based on their water and air pollution potential. Vagueness in the perception of environmental experts for ranking the technoscientific parameters in linguistic terms for the specific usage, coupled with imprecision in parametric data calls for the application of fuzzy modeling. The case study relates to the application of Fuzzy Multi Criteria Decision Making (FMCDM) for ranking different types of industries located in the State of Gujarat, India. The paper highlights the feasibility of approach for ranking the industries on basis of its pollution potential.
