Kumar Lingaya’s Vidyapeeth, Haryana, India Gopal Chaudhary Bharati Vidyapeeth’s College of Engineering, Delhi, India Global air transport operations have risen dramatically, which has led to new airport developments, requiring an in-depth effectiveness study of these investment projects, as is the case here. 6 Indian civil airports' operating efficiency between 2015 and 2018 are examined in this research. These sources were evaluated and assessed using an integrated Shannon's entropy MCDM technique. Using Shannon's entropy approach and the fuzzy WSM method, the weights of decision criteria are determined, and airports are prioritized. As a result, it is capable of dealing with the trepidation and uncertainty that accompany the subjective appraisal of input and outcome components. The findings also show that airports in touristic locations are more efficient than those in less popular places. The more convenient the airport is to the city Centre, the more passengers arrive, and the more money the airport makes. As a result, efficiency ratings are influenced by both of these elements. Airport operators and policymakers will benefit from the study's innovative efficiency analysis approach. 2021 72 85 1112 https://creativecommons.org/licenses/by/4.0/ 10.54216/FPA.040204 https://www.americaspg.com/journal/3/article/1112 https://www.americaspg.com/storage/7237.pdf
