Entropy-TOPSIS Method to Evaluate Vietnam Airlines’ Domestic Ground Handling Performance

Abstract
Ground handling is an important part of airline’s frequently outsourced services occurring in the airport. This study aims to introduce an entropy-Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) Method to evaluate Vietnam Airlines’ domestic ground handling system. The entropy will be used to calculate the weight of each criterion set by the airline company and the TOPSIS will be used to calculate the performance rankings of 17 ground handlers in 2017. As a result, “safety” is figured out to be the most important criterion and the rankings based on 7 criteria and related suggestion will also be given.
